Can not logon to a vista machine on a win 2003 network.

We are getting to error message when we try to logon to Vista machines on out win 2003 network. It was working fine fo rthe last month and suddenly this happened. There was one change on the GPO and that was to not allow the domain administartor to apply the GPO as we don't want the servers to apply the GPO.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

I can log on if I pull out the network cable and the logon, I can then plug the cable back in and work as normal. See Event Log extracts in attached file
