Users and sessions cannot be seen in the TS Mgr or the CMC on occasion. Servers are Win2k/SP3, Citrix MF 1/FR2. When I open TS Mgr, occasionally it fails to connect to one of my MetaFrame servers. If I look in the CMC, the user and session info is not listed, but all other tabs are populated. The ZDC is okay, it will report load on the affected server, and user sessions run normally. Administrators cannot manage the sessions through TS Mgr, CMC, or shadowing. A reboot will clear the problem for an unspecified period, sometimes less than a week. It can occur on any farm server. I'd be interested to see if anybody else has experienced this anomaly and solved it without SP4.
