Hello, I have a network of 13 workstation clients (WinXP SP-2 PRO) and a server with the following specs: Intel Pentium 4 640 (Prescott Hyper-Threading) 3.2GHZ FSB800MHZ 2MB L2 Cache (Not multi-core CPU!!) DDR 2GB 400MHZ Dual Channel (PC3200 200MHZ) 300GB HD ATI Radeon X330/X550/X1050 I want to setup a Domain and so I have to choose from the following two operating systems to install in this server: Windows 2003 Standard R2 DSP License Windows 2008 Standard Sngl OLP NL GOVT (Government License) From my previous experiences, I know that Windows 2003 will work perfectly on the above setup: Windows 2003 Requirements http://technet.microsoft.com/en-us/windows...r/bb430827.aspx But the Windows 2008 government license is far better than the Windows 2003 DSP which can only be used for one PC/Server. (It gets tied to the motherboard & CPU, where as government license can be carried to the next server in case I buy a new one in the future) I checked the Windows 2008 system requirements and it should work fine on my server: Windows 2008 Requirements http://msdn.microsoft.com/en-us/windowsserver/cc196364.aspx But I know that these requirements by Microsoft are never accurate and since I have never actually seen it in action I can’t judge how well it would work on my specific server. (My CPU is not Multi-core) The services I’m interested in installing are: Active Directory / Domain Controller (With 13 Domain users), DNS service, DHCP service (The Server will give Internet to the Domain PCs via the DSL/Router) & File Sharing service. (Possibly even setting up a VPN tunnel via the DSL / Router in the future to connect to another workgroup via the Internet) So based on my setup and needs, how well would I expect Windows 2008 Standard to work on my server? I would rather avoid upgrading the hardware at the moment, but I don’t want a slow/jerky server & Domain either! Should I get Windows 2003 Standard R2 instead? Any suggestions will be highly appreciated. Thanks in advance.
