We are experiencing a strange problem with AD.
In our network, with 5 sites, one HQ, 4 other offices connected using VPN tunnels we use AD. At the HQ we have a primary DC/DNS Windows 2008 R2 server, at the sites we have Domain controllers aswell. DNS Sites and Services is setup with subnets connected to the remote office DCs and subnets.
Problem: when a computer tries to ping our domain.local from lets say Remote Office A sometimes a DC from Remote Office C for ex is resolved as the DC to respond - and as the sites are not all connected there is no response.
Is this possible to resolve in DNS, seems like a DNS problem?
