Lets say we have two servers, server1 and server2. Server1 is the server where this error is occurring. If you go on server one and type \\server2 in the run dialog box you get another dialog box that asks for credentials to connect to server2. Both these servers are on the same domain and it is normal to never have to type in those credentials. So I go to the network map on server1 that's connected to a shared folder on server2 and double click it which gives me the error in the title of this post (Microsoft Windows Network: The local device name is already in use). I disconnect the network map, type \\server2 in the run box, connect to the server using admin credentials, and now the problem is fixed and I can re-add the mapped drive on server1.
I'm trying to figure out why server1 seems to be losing its connection to server2. The same thing happened like two weeks ago, and I fixed it by doing the same thing I described here. I just want to know if this is an early warning sign to another larger failure or something.
