VNC, GoToAssist, TeamViewer all extremely slow. RDP OK
Posted on 2011-09-07
A few months ago, whenever I started a session using GoToAssist to connect to a Windows Server 2003 Std. server, it becomes so unresponsive as not to be usable. However, straight RDP sessions work fine.
I've tried GoToAssist, VNC and now Team Viewer. All with the same behavior.
The session connects at normal speeds, and I'll see the console login screen, but after the initial screen appears, controls are unresponsive.
- I've tried removing each service & re-installing, only having one installed at-a-time.
- I've removed & re-installed the latest video drivers rebooting in between.
- I've added all three's program directories to the exclusion list in Kaspersky AV and had it ignore all program activity & network traffic for these programs.
There's no other software on the server that would have any effect on these program's network behaviour (ie. windows firewall is off.) GTA & Teamveiwer both can transverse NAT, and work flawlessly on my other servers/workstations I've used them on.
I've tried running these services under the domain admin account, but this doesn't work.
It seems to start working for half a second (I'll see the curson blink or CTRL-ALT-DEL brings up the login screen) but after this it freezes.
What in the world is going on here?
