Help needed with DNS conditional forwarders
Posted on 2011-09-21
I have two domains in which I am going to migrate some users across from source to target domain.
The trust doesnt work two-way because of a DNS issue with the target being able to resolve to the source domain.
From the source, I can ping all servers on the forwarded domain via server name. But I cant do the same from the target to the source.
Source domain is windows 2008 environment, domain and functional level both 2003 (cant upgrade)
Target domain is windows 2008 R2, domain and functional level bothh 2008 R2.
Target can ping source via IP. No problem with connectivity.
I add the domain.local to the conditional forwarder, enter the address 192.168.0.3 (and yes that server can ping that IP) but it cant resolve it, wont validate. Dont know how to fix this!
If I enter a host file, works perfect.
Can someone please steer me in the right direction? Doesn't make sense to me why the conditional forwarder can not validate the domain controller in the source domain.
