Some of you may have noticed the UVNC SC working slow between windows 7 machines. To fix this, you simply need to recompile your HelpDesk.exe and download the latest version of UVNC client.
Rudi De Vos over in the UltraVNC forums posted a fix for this problem.
Also, here is the link for the newest version of UVNC.
I have tested Rudi’s fix in test environment and we are now using this in production environment within Windows 7 environment and it is working great. Thanks Rudi!
