OD Replica not working

[Lisano]

We are running OD replica on an Xserve 10.4.10, of course when the network works all is great, but when the network is down we are dead in the water!!! Teachers are unable to login to their computers. I thought that the replica held all the info needed to let users login and work as usual. I am thinking that it is something with the DNS settings? When we were down, I looked at the crash log and received the “DNS cannot be resolved error”
But if any of you can steer me in a direction to start to resolve this problem I would greatly appreciate any help.
I am not the person who set up the ODM or any of the replicas, but I am the one that receives all of the back lash when things don’t work!!

Probably a dumb question.. but when the network is down can the clients even ping the server?

Not a dumb question, no we can’t ping because we are running a T1, so when the network goes down that’s it.
The replica has a separate ip then the master of course, but the way the DNS is setup ,using another server in the building, not the replica,it seems like the machines are trying to connect to the master which is across town. When I ran OD in my own building last year, I used the XServe as the DNS and set it up on the System Prefs to first resolve to this server and then down to the others. I never had a problem and so this is why I think that it could be a DNS issue. Thanks for any help.
