SYMPTOMS
A Windows NT multi-homed computer registers with one of two Windows Internet Naming Service (WINS) servers that are replicating with each other. If you change the IP addresses of the Windows NT multi-homed computer and register with another WINS server, the previous records on the first WINS server are not updated. Therefore, the new registration corresponds to the previous IP addresses.



CAUSE
An active multi-homed unique replica does not replace an active multi- homed replica in a WINS database if the owner's identifications are different (the two records are owned by different WINS servers, neither of them being the WINS server that pulled the replica).



RESOLUTION
To correct this problem, upgrade to Windows NT 3.51 (if you have not already done so) and install the latest U.S. Service Pack for Windows NT version 3.51.

To work around this problem:


 * 1) Create a static entry for the multi-homed computer in the first WINS server.
 * 2) Enter the new IP addresses for the static entry.

Inserting a static record is acceptable, because MigrateOn is set by default on a WINS server. If the node registers again with a new address, assuming the old static address has become obsolete, the new registration or its replicas will overwrite the old static entry.
 * 1) Ensure that MigrateOn is set by selecting the WINS server Advanced Settings configuration.

After the records are replicated to the WINS servers, the previous registration records, that are not used, are overwritten.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5 and 3.51. This problem has been corrected in the latest U.S. Service Pack for Windows NT version 3.51.
