Okay, first question- is the first "xxx.xxx.xxx.xxx" address the same as the second "xxx.xxx.xxx.xxx", or are they actually different addresses? Second, if we're talking two IPs, which one is the DC's IP? Basically, I can't get enough from your genericized [I made that word up] error to figure out which machine is which, where this error came from, what machine(s) is/are identified by the IPs in the error, and therefore, why I should care about the Nbstat entries. :-) Laura
