I've come across this before and it came up again today and I don't think I've blogged it. Sometimes vnc on a windows server can be particularly lethargic to the extent that it becomes painful to use. The solution I have found is to disable video hardware acceleration on the server end (Control Panel/Display/Settings/Advanced/Troubleshooting).
Slow VNC Server

Sun Dec 23 2007 18:13 about 1 year agoSorry man but I can't get to the "Control Panel", neither to the Diplay Settings. When I run VNC Server I can only get to the VNC Server Properties, in which I can't find the display settings, could u please tell me how to get to the display settings?? thanks man

This is for Windows XP, for other version of windows the names of the controls may be different but it's essentiall the same. Basicaly it is the windows display settings that need changing, not vnc.

Tue Mar 04 2008 23:19 about 1 year agoa better way to speed up the viewer is the following:
configure VNC service....
capture method.....
here change the default (use vnc hooks...) to poll for changes....
and thats it!!
enjoy a fast conection.

Thanks again Peter. Jeff
