Cannot log on

[Antoniov.]

I have some VM server in AD forest. One of these had some trouble with password: often it did not accept legal password, apparently without reason.

I thought  extract it from AD and then insert into AD again. So I changed configuration from domain to workgroup and rebooted it.

Sigh! After this I cannot log on. I used last, previous and all old password without success. It is impossible to log on.

I think I have to install Win2K3 again and reinstall software.

Can somebody tell me:

1) Is it possibile log on in some other way?

2) Is it possible extract some folder in order to save some data?

VM are based on VMWare. OS is Windows 2003.

TIA
