Wierd one. User gets error when opening files from a share: access denied. User can browse etc.
Why wierd: I have verifed effective permissions for this user at every level and it is FULL. FULL on the file and on all directories above the file except for the share root, which is expected.
User access worked fine until today when we delete and recreated his profile due to GPO issues. Those issues are resolved, but now share access is a problem.
