Our network is kind of a mess and slowly cleaning it up...here is what we have
We have an internal router (2811)...
Off of one interface FA0/0 we have our corp network which lives Active Directory and our corp servers
Off of another...FA0/1/0 we have our Wireless network (This will eventually be put on the above network but we have not had a chance to VLAN it out yet....)
Another interface we have a dev network that is fully vlaned to 4 vlans.
We're using DHCP relay (ip helper) on the router. I set the DNS on the DHCP server as our Corp AD server. We wanted our people on the corp network and on the dev network to be able to use DNS to resolve the IPs.
Some reason the computers on the dev networks are not registering with our DNS server. I do not see any errors in the logs...now sure whats going on.
My thought is for it to be in the zone I want it in they have to be a member of AD?
One additional thing is that our wireless is vlan'd and using the same DNS servers and working just great
