Guest AndiK Posted June 9, 2008 Posted June 9, 2008 Each time a node joins (after reboot or new node) our nlb cluster, some (about 10 or twenty out of 200-300 in total) active rdp sessions to other cluster members are disconnected. The nlb cluster consists of 8 servers serving 300 rdp clients, most of them wyse thin clients. Balanced traffic is only TCP 3389. All servers are Windows Server 2003 Entrise Edition with SP2. Session redirection is achieved via windows session directory. Did anyone else notice this effect or is there a known solution? Best regards Andi
Guest Munindra Das [MSFT] Posted June 12, 2008 Posted June 12, 2008 Re: RDP sessions disconnected after server rejoins nlb cluster Can you check if there is any error recorded in the event log on the client that got disconnect and/or the server from which session was disconnected? In the mean time I will try to investigate if I can find the cause for it and will reply back if I find anything. You can also try posting this to one of the Clusterning/NLB newsgroup since this seems to be related to NLB registering the new node with DNS - microsoft.public.windows.server.clustering, microsoft.public.windows.server.dns.

Guest AndiK Posted June 13, 2008 Posted June 13, 2008 Re: RDP sessions disconnected after server rejoins nlb cluster There are no related log entries on the servers as far as i remember. Nearly all clients are Wyse ThinOS based Thin Clients, and i missed to check the log of one of these machines last time. I will try to reproduce the error to check again for log entries on both sides. Thank you for the hint with the clustering newsgroup. I will do this immediately.

Guest AndiK Posted June 19, 2008 Posted June 19, 2008 Re: RDP sessions disconnected after server rejoins nlb cluster I have check the logs on our clients (Wyse Thin OS based) and on the affected servers after the last incedent (server 12 rejoins cluster, rdp sessions on server 11 and others are lost), no relevant information to find.

Guest Bertus Matthee Posted October 24, 2008 Posted October 24, 2008 RDP sessions disconnected after server rejoins nlbcluster RDP sessions disconnected after server rejoins nlbcluster We are experiencing the same issue. We have a Wyse thin OS install base connecting to Windows2003Enterprise SP2 Terminal Servers in a NLB cluster with Session Directory. When the problem occurs the users are also unable to log off from their session , because they autoatically get re-logged on their session when they try to log off. The other symptom is that their session intermittently and they need to switch off the wyse term and reconnect to the existing session.
Guest Ramasamy Pullappan [MSFT] Posted October 29, 2008 Posted October 29, 2008 Re: RDP sessions disconnected after server rejoins nlb cluster Not sure if I understand your scenario right. Your mail seems to be a continuation of a previous conversation but I have no context. If the problem is that logging off results in automatic logging back in, then it might be because of ForceAutoLogon being set. Check for the autologon related keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon Ram. -- This posting is provided "AS IS" with no warranties, and confers no rights.
