I am running an instance of SQL Server 2000. The Net_Address in sysprocesses is different when I am not connected to a network. However, when I am connected to any network, Net_Address matches the Physical Address of the computer on which I am running the SQL Server instance. Can anyone provide an explanation of why SQL Server would identify an address that does not match the physical address of the computer running the instance. Also, can this be avoided? I have a program that checks the address that SQL Server provides.
