Users cannot access email when VPN connection drops
Posted on 2008-11-17
I have two servers, both running Windows Server 2003 and Exchange Server 2003. ServerA is in SiteA and ServerB in SiteB. By SiteA and SiteB I am not only referring to two physical sites but also two AD sites. My two sites are connected by a VPN tunnel.
Both servers are domain controllers for the same domain and I recently enabled Global Catalog on ServerB.
Can anybody explain why, when the VPN connection drops, which it does occasionally, that none of the users in SiteB can access their mailboxes which are on ServerB?
Is this by design or is there a misconfiguration? Should the users in SiteB still be able to access their mailboxes on ServerB without the need for access to ServerA?
