You need to prevent the problem from reoccurring if the WAN link fails

Your network contains an Active Directory domain. The domain contains two sites named Site1 and Site2. Site1 contains four domain controllers. Site2 contains a read-only domain controller (RODC). You add a user named User1 to the Allowed RODC Password Replication Group.

The WAN link between Site1 and Site2 fails.

User1 restarts his computer and reports that he is unable to log on to the domain. The WAN link is restored and User1 reports that he is able to log on to the domain. You need to prevent the problem from reoccurring if the WAN link fails.
