NET SEND <MyComputer> Command May Not Work if Using a Hardware Profile with a Network Adapter Disabled

When you have a computer with two network interface cards in it, and you use a hardware profile to boot the computer with one of the interfaces disabled, you may not be able to run a NET SEND command to the local computername.

This problem occurs because the Netbt.sys driver maintains an internal name table, visible using the nbtstat -n command. When you run a NET SEND command to the local computername, Service Pack 4's Netbt.sys file used the first name/address mapping in the local name table, without validating it to make sure it was a legitimate address.

NetBT has been fixed to check for a valid (non-zero) IP address when looking up an IP address in the local name table.

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
