A few months ago we migrated all users and clients to a new domainb. All servers remain on domaina.
All users could access resources (email, file) in both domains with no issues.
Now I am experiencing some strange issues. Now intermittently domainb accounts cant access domaina.
I have tested with the same user account on 2 laptops, both authenticated by the same DC with total opposite results. On one every works as it should and on the other no access at all.
These issues are happening through out the domain.
I cant see anything in event logs in either domain, all servers have been restarted.
Can anyone give me a pointer on where I should be looking and what I should be looking for?
Here's a few things to try and look at.
Also, what's the reason for leaving the servers in DomainA?
Something is different, something has changed and it could be small. If you've got to machines that are the same and one works and one doesn't there may be something little you're missing.
