This is Windows 7 Ultimate 64 bit.
I use the command mstsc to establish a Remote Desktop connction to a remote server.
The login window shows up, and while I'm entering the password the system almost freezes.
Each character of the password takes 3 or 4 seconds to be accepted, and all other opened programs are not accessible.
This behavior tends to happen only the first time I use mstsc. If I used it again moments later, everything is normal.
Whar can be the cause of this problem?
