I have 2 load balanced servers running WTS 4.0 SP6 and MetaFrame 1.8. One has Citrix MF 1.8 SP 2 and the other has Citrix MF SP 3. These 2 servers are running an application which is FDA regulated, which means that there are very strict requirements as far as changes go. So, to make a long story short, I need to know if it is possible to uninstall SP3 and what are the ramifications? Will this cause problems? Anything to be aware of? Please advise ASAP. Thanks all!
