We have one Citrix Server Metaframe 1.8 SP3 on Win2K single 1 gig Intel processor, 1 gig RAM. Serving 2 published apps, MS Outlook 2000 and Siebel Call Center 2000 Client accessing a SQL 7.0 database on seperate server. Problem is with remote clients maintaining a connection to the Citrix Server. Connectivity for remotes are combination of ISDN lines (2 64K channels) with no more than 3 clients per ISDN line and DSL with max of 6 users. Individual clients will lose connection to the Citrix server receiving message on their end stating that "The Citrix Server is unavailable....". They have no trouble establishing the connection, only maintaining it. I have removed Idle Timeout settings (was 180 minutes). I can shadow these sessions and will see screens that are not complete and or entire application screen, but does not respond to mouse clicks or keyboard commands. Clients are running latest version of Citrix Client. Any thoughts would be appreciated.

Did you set the connection timeouts to Zero? Are the users on the ISDN getting disconnected or the DSL or both? Could be a timeout setup in your router that is causing this. Could also be a priority setting in the router.

Connection timeouts are not currently being used. I do not disconnect the sessions based on idle time. ISDN and DSL users experiencing same problems. Timeouts on the routers have been set to maximum length 9999 seconds (166.65 minutes). Keeping in mind the disconnect will affect maybe just one of the ISDN users at a particular location. I have no more than three per ISDN. Two of the three users will still have active sessions, the third user will drop. Additional info not mentioned: I dohave ports 1494 and 1604 both TCP and UDP open on my router.
