Pinging domain name resolves to Domain controllers that are not accessible by clients
Posted on 2013-05-14
We have an Active directory with hub and spoke topology. We have two datacenters and several remote sites. Half of all remote sites are setup with site links to one of the datacenters. There is also a site link between the two datacenters. I then setup site link bridging incase one of the datacenters is lost.
This seems to be working, however on some of the clients in one remote site, when you ping the domain name (domain.com) it occasionally resolves to a domain controller at a remote site. We do not allow communication between these sites so the ping does not work. Why is this happening? I don't know if there are actually an issues because of this, but it seems weird that this would even happen.
