DNS Server thinks Forwarder is non-recursive

Hello,
I am having a problem with one of our DNS servers. It is one of four forward-only DNS servers in our company. We have two servers acting as forwarders.
I am getting an error in this particular forward-only server's event logs (Event ID 7063), saying that one of the forwarder servers is not configured to process recursive queries, and listing the solutions - either remove the forwarder or enable recursion.
The problem is that both of our forwarders are configured with recursion enabled, i.e. the Disable Recursion box is unchecked.

Something that may be related is that in the Event Logs of the forwarder in question, I am seeing repeated occurences of Event ID 5504 - invalid domain name in packet x.x.x.x  - with one event logged for every root hint IP address. The addresses are correct. This forwarder has been set to "Secure cache against pollution".

This problem has been occuring for around two weeks now, and a reboot of all the servers in question has not changed anything. The good thing is that so far performance has not been affected, but I am keen to see all servers operating at the same levels.

Any thoughts would be appreciated.

I acutally figured out that the forward-only server was not getting what it needed from the forwarder so it was going to the internet root servers, which wont accept recursive queries. That was causing my forward-only server to report its forwarder as non-recursive.

It still doesnt solve the problem on the forwarder, but I'll accept the only answer I got.....
