Well these are just remote possibilities here.. I only mention these because you say that you could connect TO the same VNC server, FROM a workstation that was not a domain member. This suggests to me that you have an issue executing/opening a connection/resolving from the client, not an issue receiving the connections on the VNC server.
There are a couple possibilities; If the application doesn't run at all, perhaps there is a software restriction policy in place. (perhaps the domain admin(s) don't want people running VNC viewers?) Or, there could be a GPO enforced windows firewall setting. There are a host of possibilities, not knowing your environment it's hard to say - if you're not the admin, that would be a good place to start anyway! If it runs, but disappears indefinately when you hit the 'OK' button after entering the host name, perhaps it is hanging up resolving the hostname. Maybe there is something wrong the DNS in the domain? The non-domain client could have different DNS settings, or could be using WINS, etc etc. If you know the actual IP of the server, test this by trying to connect to the server from the 'non-working' system, but use the IP address instead of the hostname. If it works, then your admins have some work to do fixing their internal DNS. -----Original Message----- From: Chris Keitel [mailto:[EMAIL PROTECTED] Sent: Thursday, July 27, 2006 12:30 AM To: [EMAIL PROTECTED] Cc: [email protected] Subject: Re: VNC Viewer 4.2.5 disappears But I can connect to many other remote servers that are configured in seemingly the same way with no problem. What specifically am I looking for in terms of Group Policy settings? It can't be anything that would cause a complete block to the VNC program because this problem only occurs between our corporate domain and this sepcific server. Is there anyway to find out what VNC viewer is doing when it disappears? Does it log what it is attempting and what is is failing at?
