I have a conditional forwarder set up in Domain A to go to the DNS servers for Domain B. This works fine as standard conditional forwarders, but if I change them to AD integrated they stop working! I then have to remove the conditional forwarders and configure as standard again. If I just remove the check from the 'Store this conditional forwarder in Active Directory and replicate it as follows:' box it doesn't return to working, I need to completely remove the conditional forwarders and recreate from scratch.
Has anyone else seen this and know how to resolve?
