WINS could not start because the existent database must be converted to the Windows 2000 format. If this is the first invocation of WINS after an upgrade  From NT3.51, you need to run the convert utility (upg351db.exe in the %%SystemRoot%%\system32 directory) on the WINS database to convert it to the new  database format. Once you have done that, you should restart WINS.
