we have a 7206 with Distributed Director configured.
The Windows AD is pointing to the 7206 for certain servers that need to be redirected in the event of the primary failure.
Suddenly this has stopped working, the 7206 is not returning name requests.
Everything (servers, hosts) are showing up, but I do not see any hits accumulating on the "queries received"
I can telnet to the router on port 53 and establish a connection, but the DNS component does not seem to be working.
