If it's all layer 2 bridge,maybe a second dhcp server running? Are you running dhcp?

Are you layer 2 throughout your backhauls and tower sites? I have seen OSPF flapping causing some weird issues on layer 3 networks. If you look at the routers in the tower site, do you see anything in the log as to what is going on? Experience says it is the first site that is having issues that is causing issues behind it.

The tower that was affected by last nights lightning restarted (locally) so that wasn't it. The outages were so extensive that at one time we had 17 devices down and five minutes later 65 devices down, 10 minutes later 33, so you see where this is coming from. I went to the head end and rebooted everything from the core router on out., changed passwords on the core in case it had been compromised but show run didn't reveal anything. Oh the other thing, every computer we have started to say IP address is in use on the network, no matter what we changed it to, even a subnet we don't yet use it said it was in use. I had to repair my connection often just to do work on the network and it would work for a while then again say duplicate IP. That's why I'm convinced it's traffic. I started turning Towers back on one at a time and for about 6 towers there were no drops, I drove to the next junction site to turn more on but by then the original 6 were dropping, I turned the rest of them on but by now it's 11PM so traffic was probably lower as it's Sat. Night. Honestly I don't know what to do, Our Backhauls are all Mikrotik to our 12 towers, WireShark isn't seeing anything unusual, I have icmp packet drop in the filters. My weekend is basically ruined, what's new in this business, but if anyone has ideas I've talked to two networking gurus in town and they both said "geez I don't know you wireless guys have way bigger networks than we do". sigh.
