For the second time in 4 weeks we are getting errors when people try to log on to the Domain.
We have two servers, one 2003, that used to be the AD operations master and a 2008 newer one that currently is the operations master.
One error is coming up on the DC
Group policy management: "the domain.local forest could not be loaded and will be removed. The error message was: group policy management could not contact any domain controller in the domain that contain your user account. This may be either because of a network problem or because your account is not in active directory and a trust detection is enabled.
When i try to go to AD sites and services i get this: the directory schema is not accessible because: an invalid directory path name was passed. the menu may be inaccurate.
only noticeable errors in event log are 1053 group policy error could not resolve user name.
And 14550 DFS: namesapce service could not initialize cross forest trust information on this domain controller.
not sure where to start looking for the problem.
