I have done 1x64 server in the farm with no issue. I dropped v10 onto two Win2k3Sp2 x32 CPS 4.0 servers **Soon to be upgrade to Xenapp** and found the exact same issue on both server very similar to something that was referenced with Trend v7, the minute a domain user logons on the server hangs. http://esupport.trendmicro.com/2/Citrix-Terminal-Server-performance-slows-down-or-hangs.aspx I had to logon as a local admin and rip the client off. Has anyone come across this with v10 ?
