We have a simple network with 2 windows 2008 r2 servers that are both DNS and Domain controllers. There is a 3rd server that is for hosting remote desktop for the bulk of our users. We recently decommissioned a Windows 2003 server that was doing very little and was not  a DC. The network shares seem to drop randomly and cause interruptions in the applications that need to communicate from the workstations to the servers. We've thoroughly checked DNS on Both machines and all looks well, no errors, and no best practice errors show.

No best practice errors show? What best practice analyser are you running?

You should NOT be running file shares on a DC. It is a security risk, puts a load on a DC that is expected to be available for other things and is generally considered the worst of bad practices.

If you are running Windows 2008 servers with less than 50 users - there really is no problem sharing files on a separate data harddrive. If MS thought that it was going to cause major problems - they wouldn't put "file sharing" as one of the available features.  Real world - 90% of small business clients have a single server and they don't have a problem. I have dozens of Client running 2008 server and the best practices scan have never said not to have file shares.

Now getting back to the real problem - This normally happens when the person who installed the server and or workstations did not change the little check box on the network adapter configuration that says - Allow windows to turn off this device to save power.  This is always set to checked and it never should be except on a laptop - and NEVER on a server or a workstation that has network shares.  You may as well turn off your switches and routers if they don't have any traffic going through them.  Once that connection breaks you get a disconnected network drive. Most apps will not connect to a disconnect network drive - until you go to the Computer and double click on the network drive to re-establish the connection

Ok looks like I had the primary and alternate DNS settings swapped between the two DC's. IE 192.168.1.223 on the .223 machine and .227 as its alternate; and the reverse on the .227 machine. Thus replication was failing and everything else went south,
