Hi, R2 will not add extra Terminal Services functionality... But when you're building / deploying new servers why won't you use the latest software build?. Terminal Servers with Windows Server 2003 R2 works fine for our customers , and R2 has some licensing advantages when using in a Virtualization environment. You can buy one Windows Server 2003 R2 Enterprise License en use 4 Virtual Machines with this one license!. With regards, Ruben Spruijt ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Matthew Shrewsbury Sent: Tuesday, September 05, 2006 7:44 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] PS4 with Windows 2003 R2 or not? I'm about to deploy new servers into our Citrix PS4 farm. Should I use R2 or just standard Windows 2003? If so then why? Thanks, Matthew Shrewsbury, MCSE+Internet MCSE 2000 CCA Server+ Network Manager
