Things to check: Citrix, in my limited expirience with it, seems to be extremely finiky with connections. If you have a faulty connection, Citrix will get all sorts of peaved. =20 I would check: 1.) Station's NIC 2.) Cabling (patch cables, structural, etc.) 3.) Port on Hub/switch/router 4.) Analyze what is occuring on the packet and hardware level when this problem occurs. Possible cause: 1.) "Chatty NIC" 2.) Wiring gone bad 3.) Port on Hub/Switch/Router going bad Or, this might not be the case. If not, the client might have some kind of conflicts with its internal settings. Check the client config file, set keyboard and mouse from 0 to 300 as this helps with connections. Also talk with Magnus and John K. They always have good ideas and have helped me out in the past. Hope this helps. Respectfully, Lucas W.

The immediate fix is for them to just hit refresh. The ICA Client then asks them to authenticate again and the applications work fine. =20 =20 Easy fix yes, but we are about to upgrade the rest of our corporation and want to prevent this problem. Does anyone know what may be causing the client to lose its authentication? I can not duplicate this problem on my workstation. =20 =20 =20 Michael White AIM Investments =20 ******************************************************** This weeks sponsor - RTOSoft TScale=20 Complaints about applications response time - DO SOMETHING ABOUT IT!
