Firstly, sorry if this is the wrong area for this question/discussion, I am happy to move it to a more appropriate area.
We have recently replaced our Windows 2008 R2 Management Server with a Windows 2012 Server. This server is used by support staff as a central place to run various management consoles, administer various services and to administer shares and file permissions etc.
It is often used to manage share permissions and local group membership on many of our Netapp vFilers, via "Computer Management". We have now discovered that trying to manage vFiler local groups from Computer Management on Server 2012, returns the error:
"The following error occurred while attemptiong to read group properties: The tag is invalid."
We have also found that trying to enumerate effective permissions from a UNC path to a folder in a Share on a vFiler (eg. \\vfiler01\someshare\somefolder) returns the error:
"Code: 0x80070057 The parameter is incorrect."
Neither of the above problems occur when using Server 2003 or 2008.
Is anyone aware of a fix for these issues, or of a Netapp document that outlines any known combatibility issues with Windows Server 2012?
Any advice would be greatly appreciated.
Go into your filer(s), run: options cifs.tcp_window_size
If it is 17520 change it to 64240: options cifs.tcp_window_size 64240
Restart CIFS on your filer(s)
