Please be nice with my english because I am french.
I am using a W2k3 server. After being athenticated with ultraVNc (the password is accepted and the Microsoft authencation window appears) the logon "username & password" are grey an locked. I can't access to those fields.

The only way to unlock those fields is to reboot the computer.
Can anyone help me please?? have you any peace of information to solve this problem?
Thank's for all.
