The English version of this fix should have the following file attributes or later:

   Date         Time   Version        Size     File name
   --------------------------------------------------------
   27-Feb-2002  10:19  5.0.2195.4985  135,952  Dnsapi.dll
   27-Feb-2002  10:19  5.0.2195.4985   95,504  Dnsrslvr.dll

WORKAROUND

Because the records are not directly useable by the client, the records should not be queried from a remote computer. WINSR records are designed for internal DNS server usage, to make reverse lookup of WINS-only clients possible for DNS-only-based clients.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 3.
