After you remove File and Print Services for NetWare (FPNW) an error is
posted in the Windows NT 4.0 Event Log:
Event ID 12291: SAM failed to start the TCP/IP or SPX/IPX listening
thread.
The error is benign and causes no loss in functionality.
NOTE: FPNW may have been removed when running Windows NT 3.51 as required
by the upgrade to Windows NT 4.0, this will also cause error 12291.
CAUSE
This may be due to a failure by the FPNW uninstall process to remove two
registry values under the LSA Control key.
WORKAROUND
If the following two values exist in the registry, remove them to prevent
further occurrences of this error.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA\
NetwareClientSupport
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA\
