New Powerful Server Chip by Intel

Intel Corp will start producing a new, more powerful version of its Xeon multiprocessor chip for servers in the second half, a spokesman said on Tuesday.

The new chip, code-named Nehalem EX, will go on sale in the first quarter of next year. No prices have been announced for the new chip, which will succeed the Xeon 7400, priced from $1,100 to $2,700.

The Nehalem EX will provide two improvements. First, it will increase the number of cores inside a single chip from six to eight. Second, each core will be able to handle two "threads" of software instead of just one.

Severs will be able to handle up to eight of the sockets for the powerful new chips, and third parties can expand beyond that, according to Intel's Nick Knupffer.

Further technical details are available here .

Intel produces several lines of central processing units. Its multiprocessors are its most expensive, sophisticated line, used for running large servers. It also has smaller, powerful chips to run desktop and laptop machines.

Basic information of Remote desktop

Remote Access Services lets you connect your computer from other location location, such as your home. We can access computer remotley home to office or office to home. when we take remote that time client site automatically lock the computer. choose will depend on many factors such as cost, connect and transfer speeds, reliability, availability, etc.remote access to SLAC Windows resources. The remote client, using dialup or cable modem or DSL with a public Internet Service Provider(ISP), connects to the Citrix/Windows Terminal Server farm within the SLAC internal network. The processing of applications for the remote client session is moved completely off a user's desktop and onto the centralized server farm. Only screen, mouse, and keyboard information is passed between the client and the server using thin-client technology. we take remote locally entire netork.

Remote Access service:
combination of hardware and software to enable the remote access to tools or information that typically reside on a network of IT devices. Microsoft when referring to their built-in NT remote access tools, RAS was a service provided by Windows NT which allows most of the services which would be available on a network to be accessed over a modem link. It is not necessary to run Windows NT on the client - there are client versions for other Windows operating systems.RAS works with several major network protocols, including TCP/IP, IPX, and NBF. vpn is also part of remote. but some diffrence.

Remote desktop:
This software package already installed but we want only configuration. server site and client portion of Remote Desktop on any of the following operating systems Windows 95, Windows 98 and 98 Second Edition, Windows Me, Windows NT 4.0, or Windows 2000, Windows XP Service. When we enable this option that time ask me you want access remotley your computer another people. we can not configure this option on remotley. this option should be we configure locally computer.remotely connect to a computer running Windows XP Professional with Remote Desktop enabled.With the Remote Desktop feature in Windows XP, you can remotely control a computer from another office, from home, or while traveling. This allows you to use the data, applications, and network resources that are on your office computer, without being in your office.

Remote installation service:
Remote Installation Services was introduced with Windows 2000 as an optional component when installed on Windows 2000 Server. Initially, it supported only the distribution of Windows 2000 Professional, but with Service Pack 3 allowed for the remote installation of Windows 2000 Server. RIS was updated twice; once to support Windows XP, and again to support Windows Server 2003. With the release of Service Pack 2 for Windows Server 2003, RIS was replaced with Windows Deployment Services.Windows 2003, two services are required to provide Remote Installation Services: DHCP and Remote Installation Service. without dhcp we can not install remotly.

Basic information of group policy, windows server 2003

Group policy:
............
Group Policy management solution allows administrators to define configurations servers and user machines. Local policy settings can be applied to all machines Group Policy to set policies that apply across a given site, domain, or range of organizational units, Support for Group Policy is available on machines Windows 2000 Server, Windows 2000 Professional, Windows XP Professional, and Windows Server 2003.Group Policy we used to define user-related policies as well as security, and other policies applied at the machine level. Group Policy enables management of domain controllers and member servers as well as desktop user machines.

Group Policy Management Console provides a unified, graphical user interface. managing Group Policy implementations and enables script-based management of Group Policy operations Server 2003 adds even greater administrative control to Group Policy, including more than 200 new policy settings for the operating system. administrators can be configure standard computing environments for groups of users and computers. Group Policy, administrators could be define the policies that determine how applications and operating systems are configured and keep users and systems secure.

Administrator can be configure registry based policies for applications, the operating system and its components administrators can configre security options for computers and users within the scope of a GPO. Local computer, domain, and network security. Administrators can be configure application installation, updates, and removal centrally with Group Policy. group policy is a more powerfull part of windows server 2003. user what to do administrator can be configure. user can't change his group policy without admin permition or take admin right.

Basic information of DHCP

Dhcp server: Dhcp server provide Ip address his client automatically. defined range of numbers Client computers configured to use DHCP for IP assignment do not need to have a statically assigned IP address.it define by default eight days. when 50% time over then client send send a request on server. next when 87.3% time over then again send a request client onserver. and when 100% time over then again client machin send a request. that time mostly release again ip Ip may be same or diffrent this is not fix. if any case server fail then five minute wait all client machine then provide apipa ip apipa available in registry client machine. apipa range = 169.254.0.0 -169.254.255.255

DHCP server never assign permanently IP address it provide by default eight days. administrator can be fix any ip on patricular machine base of mac address because mac accress always uniqe address never match another lancard word wide. If admin fix any ip paticular machine then never change ip. They generally do not need to have addresses configured for DNS servers or WINS servers, as these are also set by the DHCP server.A user turns on a computer with a DHCP The client computer sends a broadcast request looking for a DHCP server. server receives the DISCOVER packet. DHCP uses the same two IANA assigned ports as BOOTP: 67/udp for the server side,and 68/udp for the client side.

The server also configures the client's DNS servers, WINS servers, NTP servers, and other services as well. client sends a request packet. server sends an Acknowledgement packet, confirming that the client has a ip address. When a computer uses a static IP address, it means that the computer is manually configured to use a specific IP address.If you use DHCP servers to automatically configure the TCP/IP settings for workstations in your organization, a DHCP failure can lead to a major disruption in service.

Basic information about Terminal Server Support

Terminal server:Terminal Server product Microsoft software that service the Windows desktop and applications to terminals.a terminal server is feature inbuild with server operating systems. server that provides terminals with a common connection point to a local or wide area network.Terminal Services, is one of the components of Microsoft Windows that allows a user to access applications and data on a remote computer over a network.

Terminal Services was first introduced in Windows NT 4.0 Terminal Server Edition. It was significantly improved for Windows 2000 and Windows Server 2003 and windows server 2008. Windows includes two client applications which utilize terminal services: the first, Remote Assistance is available in all versions of Windows XP and allows one user to assist another user.

Terminal Services allows IT departments to configure this applications on a central server. For example, instead of deploying database or accounting software on all desktops, the applications can simply be installed on a server and remote users can log on and use them via the Internet. if we are working in locally network and then no need internet. windows 2000 server give only 90 days subscription after that expire. at a time only two user connect. if we want and the purchase license. and windows 2003 server provide 120 days subscriptions. in windows server 2008 five user connect at a time.

Remote desktop:Remote Desktop, allows a user to log in to a remote system and access the desktop, applications and data on the system as well as control it remotely. this is only available in certain Windows editions. These are Windows NT Terminal Server. subsequent Windows server editions. Windows XP Professional, and Windows Vista Business, Enterprise and Ultimate. In the client versions of Windows, Terminal Services supports only one logged in user at a time, where as in the server operating systems, concurrent remote sessions are allowed. is the client application for Terminal Services.

It allows a user to remotely log in to a networked computer running the terminal services server. RDC presents the desktop interface of the remote system, as if it were accessed locally. if we want configure remote desktop feture then go locally enable remote desktop feature. if we enable these feature then hibernation does not work. you can say this is disadvantage. when we take remote any computer that time client machine automatically lock.

Ways to Enable BranchCache?

You must also create the required firewall exceptions and ensure that the files you wish to be cacheable have a hash generated on them. The easiest way to configure BranchCache is via Group Policy.

First, you need to make the server hosting the data generate hash values. Open a Group Policy Object. Navigate to Computer Configuration, then Policies, Administrative Templates, Network, Lanman Server. Double-click Hash Publication for BranchCache. Set this to Enabled, then configure when the hash should be generated, as shown here. You can generate hashes if a folder is shared and enabled for cache (recommended), never generate a hash, or generate a hash for every shared folder. Make a choice and click OK. Click to expand.

If you configured the server to generate a hash only if a shared folder is set to use caching, you need to Right-click the shared folder in Explorer and select Properties. Select the Sharing tab. Click the Advanced Sharing button. Click the Caching button. Check the Enable BranchCache option, as shown here, and click OK to close all dialogs. Click to expand.

You can also use the hashgen command to force a hash generation for other files, such as web files served via HTTP.

If you're using hosted cache, you now need to enable the BranchCache feature on a Server 2008 R2 server. For this walkthrough, I'll configure distributed cache (peer to peer).

The next step is to enable BranchCache on the clients. Again, I'll use Group Policy. Navigate to Computer Configuration, then Policies, Administrative Templates, Network, BranchCache. Double-click Turn on BranchCache and set it to Enabled. Because you're using distributed BranchCache, double-click Set BranchCache Distributed Cache mode and set it to Enabled. You can also configure the latency required before caching is used.

You probably don't want to cache data if the connection is very fast, so you might only cache if the latency is over 70 ms. Double-click Configure BranchCache for network files, set it to Enabled and set the latency. In the example here, I set latency to 0, so everything is cached. Click to expand. Note that you can also set the amount of disk space to be used for the cache on clients. The default value is 5 percent. Use the Set percentage of disk space used for client computer cache option to set this value.

Now you need to enable two firewall rules. Navigate to Computer Configuration then Policies, Windows Settings, Windows Firewall with Advanced Security, Inbound Rules. Select New Rule from the right-click menu. Under HTTP, Port, TCP 80, create a rule to allow all profiles (or just a domain, depending on environment). Also create a rule under WS-Discovery, Port, UDP 3702 to allow all profiles (or, again, just a domain), as shown here. Click to expand. Close the GPO

At this point, you have a GPO with all the required settings. Make sure the GPO is linked to the client and the client refreshes its policy, either by rebooting or using the command gpupdate /force.

SharePoint 2010 will require 64-bit SQL Server

SharePoint 2010 will require a 64-bit version of SQL Server and it will not support Internet Explorer 6, according to Microsoft.

At the company’s annual TechEd conference, Microsoft also revealed that SharePoint 2010 will not be available with the Office 2010 beta that it plans to ship in July.

“That release will mostly focus on the client side,” said Tom Rizzo, director of Microsoft SharePoint Server, during his conference session.

Microsoft will release that beta to a select group of testers, but has said previously there will be a public beta.

Rizzo said during the session that it was a “painful decision” to drop support for IE 6, but that Microsoft would support an array of browsers including IE 7 and beyond, Firefox 3.x on Windows and non-Windows platforms, and Safari 3.x on non-Windows platforms.

As far as the 64-bit support, Rizzo said as gently as he could, “You have been warned.”

SharePoint 2010 will run on the 64-bit version of Windows Server 2008 and on SQL Server 2005 and 2008.

Rizzo also said SharePoint 2010 would feature Fast Search for SharePoint and Fast Search for Internet Business. Microsoft last year purchased Norway-based Fast Search & Transfer, which developed enterprise search software.

Buy Home Server in Less than $ 400

Unfortunately, Windows Home Server suffered early on from a serious data integrity problem. Personally, I believe that this flaw alone damaged the product’s initial foray into the nascent home server market. Now, with the release of Windows Home Server Power Pack 2, a whole slew of new devices based on the operating system are being released, including the HP LX195.

Priced at $390, the HP LX195 includes the following:

* A 640 GB 7200 RPM SATA hard drive - upgradable to a larger size.
* 1 GB RAM - also upgradable
* 1.6 GHz Atom processor
* A very attractive, 4 inch wide x 8 inch tall x 8 inch deep case
* 4 USB ports make it easy to add additional storage and to perform backups
* A gigabit Ethernet port
* 28 W power consumption when the hard drive is in use
* 3.5 W power consumption when the hard drive is asleep

At first glance, you might laugh at what appear to be ridiculously weak specifications for a server product, but it’s important to bear in mind that this product targets the consumer market - hence, Windows “Home” Server.

As is the case with HP’s original home servers, the EX470 and EX475, the LX195 boasts a ton of features that are bundled with Windows Home Server. Further, although the upgrade options with the LX195 are relatively limited, you can upgrade the RAM! With HP’s original EX470/475, upgrading the RAM (the base was a paltry 512MB) was extraordinarily difficult and not supported by HP.

Here are some of the features included in Windows Home Server:

* Client backup and restore. I’ve actually performed a bare metal restore of a client using my EX475 Windows Home Server’s backup and restore capability. The process simply couldn’t have been easier.
* Remote access. Windows Home Server includes complete remote access capability that lets you browse the file system and download files. Further, once logged in to your Windows Home Server remotely, you’re able to use Remote Desktop to connect to any computer on your home network.
* Media sharing. Windows Home Server supports any devices that uses Windows Media Extenders, including PCs running Windows Media and Xbox 360’s. I’ve personally mad heavy use of this capability to watch movies and listen to music via my Xbox 360 that is stored on my home server.
* Central file storage. My wife and I, between the two of us, use five computers - Four Windows machines and one Mac. Being able to access files from a central location is really nice!

Windows Server 2008 R2: Beta's Upgrade Functionality

The base release of Windows Server 2008 came with upgrade functionality. The feature was unavailable, yet the button was there, so we knew it was coming.

Among the Windows Server 2008 R2 beta's functionality improvements on Windows Server 2008 is that the upgrade functionality is now available.

For most upgrade scenarios, the process would occur in a currently running version of Windows. The upgrade option is shown in Figure A.

Windows Server 2008 R2

In-place upgrades of Windows server systems are very rare, but they do happen. This functionality is currently only applicable to systems running an x64 operating system; the upgrade will not function on x86 editions of Windows Server. This effectively means that the base release of Windows Server 2008 was the last server operating system with an x86 option.

The upgrade functionality option fits well in the IT landscape right now. For new Windows Server 2008 installations, be sure to select the x64 edition during your initial build, so the migration to R2 will be rather seamless when it comes out. Many general purpose servers that are on x86 editions are not offered a native upgrade option.
