  Hello, 

  When VPN disconnects, there is no communication between central office and remote office locations. So, no communication between DC and client systems and users are not authenticated by DC, it leads a problem in accessing file server.

  I suggest you configure another DC/DNS/GC server in other 2 locations or configure network redundancy at 3 locations.

  Please go through below two articles while configuring DCs at remote site/locations.

  Hi,

  Thanks for posting here.

  Domain computers and users need to connect with domain controller to complete the authentication during the accessing process. So once the connectivity is no longer available then they will not be able to access with each other anymore.

  Please following what Ravikumar suggested to deploy a domain controller at remote site with setting “Active Directory Sites and Services” in domain system in case the issue you encountered reproduces in future .

  Hi,

  
  Thanks for update.

  I’m afraid there is no other way but consider to deploy an additional domain controller at branch site and configure it to replicate with DC at central site like what we suggested previously .

  We also have new read-only domain controllers feature in Windows Server 2008 which will help to secure our domain system at branch:
