SYMPTOMS
When a multihomed computer tries to connect to another remote computer, not all of the adapters resolve the name to the IP address specified in lmhost file. Also, this occurs even if the remote computer name is in the lmhost file with #PRE. Name Query request might still be sent out on some interfaces, and if there is no response, connect requests may not be sent on all interfaces.



CAUSE
The behavior is due to a regression on an enhancement done to NetBT as explained in Q216471 - NetBT Improvements for Connections Between Multihomed Computers.
