I noticed this error in my Server Roles "File Server" log:
While transmitting or receiving data, the server encountered a network error. Occassional errors are expected, but large amounts of these indicate a possible error in your network configuration. The error status code is contained within the returned data (formatted as words) and may point you towards the problem.
0000: 000040000 002C001 00000000 800007DC
0008: 000000000 C000184 00000000 00000000
0010: 000000000 0000000 0000058F
Is this something to worry about?
