We are currently running Citrix Metaframe 1.8 for TSE on our NT4 network. We have recently purchased the upgrade to MetaFrame XP and plan to run it on a windows 2000 box. I need to know if installing this will in anyway affect the existing server. Our current web server is on the internal LAN and houses NFuse. The Web Interface for the MetaFrame XP server will be installed on our new DMZ Web server along with CSG. Can anyone tell me if this is ok? Also, when I tried to install TS on the Windows 2000 machine, it asked if i want it in TS for Windows 2000 or TS for NT 4.0 users and talks about legacy apps. What do I select? Thanks in advance.
