You try to enable FILESTREAM settings by using SQL Server Configuration Manager in Microsoft SQL Server 2008 or in SQL Server 2008 R2. When you do this, you may receive the following error message:

There was an unknown error applying the FILESTREAM settings. Check the parameters are valid

This problem occurs after you upgrade to SQL Server 2008.


This problem occurs because the Filestream file share resource expects the following Microsoft Windows NT path:

\\?\GlobalRoot\Device\RsFx0102\MSSQLSERVER However, the Cluster service does not accept a Windows NT path.


To resolve this problem, install hotfix 937444.
