Hopefully, some one knows what this is. I've opened a case with Microsoft 4 months ago, and they still have yet = to figure out that it is.=20 Problem: At anytime during the day, a terminal server, running Citrix, = will report the following error in the event log: The session setup to the Windows NT or Windows 2000 Domain Controller \\PRCPDC for the domain PRCWF is not responsive. The current RPC call = from Netlogon on \\PRC-MF5 to \\PRCPDC has been cancelled. This server has about 30-40 users on it and when this happens, everyone get's completely locked up. I cannot log into the server in console = mode. I have to power it off and reboot. =20 I have a PDC and BDC. If I leave the console logged in and this = happens, I can ping both PDC/BDC by IP, by name and I can NBTSTAT -A IP. I ran a sniffer for a while and sent them in to Microsoft for examination. This = was 3 weeks ago. I've been handed around to 3 techs and they claim = everything looks fine in my DNS/WINS. I even edited a lmhosts. File to point = directly to the PDC....I need heklp on this. It happens to 4 of my servers all running: Compaq Proliant DL series (380 & 360) Windows 2000 w/ SP3 Citrix MF 1.8 w/ FR-1 sp2+ Connected to a Cisco 4003 switch. Need help on this.
