Services for Macintosh (SFM) is not supported when it is installed on a shared cluster array. In Microsoft Windows NT 4.0, this is because of architectural restraints imposed by AppleTalk. In the versions of Microsoft Windows 2000 and the versions of Microsoft Windows Server 2003 that are listed in the "Applies to" section of this article, SFM is not supported because SFM maintains state information in memory. Specifically, the Macintosh volume index is located in paged pool memory. Using SFM in clustered mode is not supported and may result in data loss.
You may be able to use a Macintosh if you use a third-party Server Message Block (SMB) client for Macintosh.For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
