As the subject line suggests, when I enter the list of Forwarders under the domain controller "properties" the list stays there for about 20 minutes and then disappears. The list of Forwarders on my secondary DNS server (secondary as that as how it is assigned to domain PCs via DHCP) remain in tact.
This is causing lookup requests that run through the PDC emulator to timeout. I'm looking for hints on if this is a common issue and there's a handy blog post about it or if there's a way to troubleshoot what's going on.
