Hi,

When I try to add or edit a protection group (on my seconadry DPM server) which points to my primary DPM server the MMC crashes with the following error:

__________________________

Description:

AppName: mmc AppVer: 4.2.1205.0 ModName: mmc.exe

ModVer: 6.3.9600.16384 StackHash: 37C84C07

Problem signature:

Problem Event Name: DPMException

Application Name: mmc

Application Version: 4.2.1205.0

Module Name: mmc.exe

Module Version: 6.3.9600.16384

Exception Name: System.NullReferenceException

Exception Point: Microsoft.Internal.EnterpriseStorage.Dls.UI.ObjectModel.FileSystem.FsDataSource.ToString

Other: 37C84C07

OS Version: 6.3.9600.2.0.0.272.7

But...going through any other route (ie - seconary DPM server, Filecluster, etc) is absolutley fine.  It only seems to be when I try to go through the primary DPM server that it crashes.

Any help would be very much appreciated.

Thanks in advance.

I have seen this type of issue before. Make sure both your DPM servers are on the same exact version. Also be sure to apply the latest UR6. You can find version here:
