How much RAM can a Citrix Presentation server support? I know that with Windows Server 2003 Standard I am limited to 4GB, but with Enterprise I can go up to 64GB. However, I read this article from Brian Madden: http://www.brianmadden.com/content/article/The-4GB-Windows-Memory-Limit-What-does-it-really-mean- and it sounds like there is a 2GB kernel memory limit regardless of which version of Windows 2003 Server you run and with Terminal Services, all users are affected by this kernel memory limit. Is that a fair statement? Without virtualizing, how much RAM can I realistically put in a Citrix server and take advantage of? Thanks guys!
