Compare sharing permissions and NTFS for the relevant user.
“Check fees” should produce an observation that clearly confirms or rules out “share rights or NTFS insufficient”.
If the observation is normal, lower “share rights or NTFS insufficient” in the ranking and continue with the next distinct check.
If the observation is abnormal, keep the evidence and investigate “share rights or NTFS insufficient” first. Related action: adjust LCAs without giving excessive duty.
Repeat the same validation test after the correction and confirm the original symptom is gone. Validate stability before closing the incident.
Before changing configuration, record the current value and a way back.
Crack if multiple SMB servers become inaccessible at the same time or if errors indicate a Kerberos, DFS or domain problem.
