For clarification.
My reason for the question is I would like to use Linux to replace the MS 2003 servers I have that running terminal services on. Our situation is we have centrally located files that need to be accessed by remote locations across T-1 lines. The time it takes to open assembly files across the WAN can be 40-90 minutes easy. To eliminate that wasted time I have set up servers running Ironcad that the users access remotely. The same files now open in 5 minutes or less. However, the overhead and cost to support the MS servers in a Novell network environment is prohibitive not to mention the video refresh lag (minimal but noticeable) a terminal service window has when rotating graphics. I envision using X services on a clustered Linux server setup to solve or at least improve my issues.
