VDP stop working after domain administrator password change.

We recently changed domain administrator password and stop the domain administrator permission to the vCentre. Looks like now the VDP machine stop working.

The symptoms are: cannot access VDP via web, only ssh.

I looked trough the vdr-server.log and there are a lot of these errors:
