Cause
MTU size on the Port of NAS Server Interface is different than the MTU size on the Domain Controller.
Resolution
The difference in MTU size on the Port on which NAS Server Interface is created and that of the Domain Controller does not allow Domain Controller to read the frame sent from NAS Server resulting in failing of the Domain join operation.
To resolve the issue adjust the MTU size on the Port on which NAS Server Interface is created , or on the Domain Controller. Make sure they have same MTU size.
