GPolicy not working correctly - causing issues

iamuser used Ask the Experts™
Group policy issue. So I am seeing a number of these messages from workstation machines within a specific OU. Security policies were propagated with warning. 0x534 : No mapping between account names and security IDs was done.

GPresults give me no errors but when I run RSOP on the workstation I see a number of red 'X' next to specific settings.

I also do not have a winlogon log that I can use. I don't know what is causing the problem, need some help

A  Red Circle White X  on a Computer or User configuration means the computer or user configuration is not applying this policy.

Have you right-clicked that node and selected “Properties"? It should come up with a detailed error message that tells you what's wrong.

Are you running the admin console with the right elevated permissions?

It could relate to a workstation not being trusted on the domain.

Could also be a corrupt policy.

You mention this is only happening on a specific OU.  If you apply this policy on a different OU, does it still happen?

If you move one of the offending workstations to a different OU, does it have any positive effect?
