After you upgrade to Windows NT 4.0 Service Pack 4 (SP4) and view theOperators tab on an SMTP, IMAP, or POP3 virtual server, the virtual serveris no longer viewable through Microsoft Management Console (MMC), even bythe administrator.
A change in the Internet Information Server (IIS) ADSI provider for themetabase causes this problem. When the SMTP, IMAP, or POP3 snap-ins savethe metabase ACL for the Operators tab, a bad ACL (that does not includethe administrator on the local computer) is written to the metabase. Noerror is returned by the ADSI provider, therefore the snap-ins commit thechange to the metabase.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
