urgent help, VNC connection dropped, Reconnect to it.

[monday8848]

Hi: I deployed ultravnc10962 to win7 32bit computer with no mirror drive installed. I found a strange issue today. Connection have been dropped many times(about 3 -5) in one minute. I test it in several win7 32bit computers, All of them have the same issue. Connection dropped, When connection dropped, VNC viewer attempt reconnect to it. And VNC server show acception window(I enable the display query window), I use MS logon I authentication. And encrypt the session with SecureVNCPlugin. And use a domain account for connection authenticate. This never happen when I test deploy VNC in win7 32bit test computers. Does someone know the reason? BTW, I want know, Is there need frequently authentication during the connection session? I mean If viewer want connect to Server, There just happen one authentication, or many authentication during the whole connection session? thanks.

I already fix this problem, I use MSlogon I to authentication seesion, I already set group 1 to allow access VNC server. It should have a domain group in group2, But I forget set group value, Meantime I check the domain box in group2 line. This is the reason. After I fill a domain group in group2, It's running well, And connection never get break. Maybe this is a VNC bug, Because I deploy VNC server to 10 Win7 computers through GPO policy, Both these win7 computers have the same problem--connection break. Hope deloper can research this.
