No, there is almost no traffic through the port. I was thinking something more along the lines of creating a forward lookup zone, to accomodate the routers IP but wasn't sure how to do it correctly.

Question
How to integrate Cisco 1841 WAN router into windows domain.
I have a Cisco 1841 WAN router that connects my company to a japanese network for a few users. Their pc's were configured from the mother company before they arrived here to use the 1841 IP as their primary gateway, my DC as DNS. I don't have a secondary DNS at this time. The problem is that every time I plug the 1841 into my switches after about 10-15 min the network drops all the other users. This router was already here when I inherited this position, and hasn't been an issue until a server that was the secondary DNS had a meltdown. I don't know Cisco very well, but had the WAN circuit provider checked the 1841 out and they didn't detect any malfunction. I'm suspecting that there are some DNS changes that need to be made to the DC to accomodate this device. Any help would be appreciated.

First I apologize for leaving this question hang for so long. Anyway, i temporarily fixed the disconnection problem by setting my users IP's to 10.1.1.x instead of 10.1.x.x, which I shouldn't have had to do because my mask is 255.255.0.0. The device is not the gateway to the outside, only for the few users who need to connect to Japan. Its mask is 255.255.255.0 to comply with the Japan network I assume. I still don't understand why this seems to radically affect the rest of the network.

Sounds like a security "feature" some kit can shut down ports if it's getting packets from lot of MAC addresses in the same port. The switch thinks it's being DOSed or something similar so shut's the port down. Sorry I don't know a whole lot about this but it might be a direction to start googling!
