I have added a secondary domain controller at our branch office and created a site and replication setting for it, however the vpn connectivity between the two branches is intermittent, ie. we lose connectivity at least 4 to 5 times a day.
There is only one domain that is being used.
The problem I am having is when there is no vpn site connectivity, the users at our branch office are not able to access resources from the secondary domain controller, like the print server and file server (therefore they are unable to print or access any shared files) because the Secondary DC tries to authenticate the users by contacting the Primary DC. The Secondary DC is also a Global Catalog Server.
Is there a solution to this problem?
Is it possible for the Secondary DC to authenticate users without contacting the Primary DC?
