Hi all,
I'm completely lost with errors on a Server 2008 r2 AD.
Here's my symptoms:
- Computers are losing trust relationship - unable to rebind - Error "The following error occurred attempting to join the domain "domain.local": Cannot complete this function"
- Hundreds of errors every minute in System log saying Event 12292 "The SAM database was unable to lockout the account of Guest due to a resource error, such as a hard disk write failure (the specific error code is in the error data) . Accounts are locked after a certain number of bad passwords are provided so please consider resetting the password of the account mentioned above."
- Unable to make any changes in AD. I can't disable accounts, edit groups, add users, delete users, etc. Any attempt to make a change to an AD item results in:"Windows cannot ... because: An internal error occurred."
- AD is not replicating to the other DC. Attempts to replicate give the error"The target principal name is incorrect"
This seems to have started over the weekend or late Friday. I was told that one PC that lost trust relationship started on Sunday.
The only change I've made recently is resetting WSUS because that stopped working. That was early last week and after it's initial sync, it was running alright - except using tons of memory.
No idea where to go with this. I'm a novice at Win server.
