All of our servers are 2003, the login script maps drives to the server.

Recently all of our users during the course of the day will drop thier mapped drives. and if you try to manually map user cannot connect.
So far the only thing that work is if the user reboots the computer, but some times it might take a couple of reboots before the drives will map again.

when I have done some searching the responses are pointing to the DNS server.

Two of our servers provide dns and all the clients point to both.
the domain we use here is not the same for our internet domain.

any ideas

I would suggest looking at the settings on your switches in your network. I would turn on Fast Link for the ports that workstations are plugged into. Also seen that referred to as Port Fast. Just depends on the vendor of the switch. I experienced what you described above when we switched over from the HP Procurves to the Dell PowerConnects. Turning on "fast link" resolved the issue.

That's an obscure solution. Have to keep in mind if I ever leave HP for switches.

I doubt DNS is your mapped drive disconnect issue. That is usually a malfunctioning nic on the server or your backbone switch is having problems. All it takes is a seconds worth of hiccup to drop the maps.

Do you have a managed switch(es)? If so look at the port logs and switch logs. Look at the server event viewer logs for clues.

Your not being able to reconnect without rebooting though indicates a larger issue.

It is OK if they use different dns servers if those servers match in providing information. Are they Ad intergrated or primary/secondary dns servers? Entrys between the two match?

Imagine the power of knowing how to internet search
