When SQL Server 2000 sp3 ( on Windows 2000 Server ) starts, the Server error log reports the following:
SQL Server listening on nn.n.n.n:1433
SQL Server listening on nnn.nn.nn.nnn:1433
SQL Server listening on nn.nn.nn.nn:1433
The last entry is the IP address of the actual server. What do the other "listenings" mean?
