One of our customers ran in to the problem that the DPM Console Kept on crashing when selecting the recovery Tab in the DPM console.

Check for duplicate servers in database
The error could be caused by duplicated names of Protected servers in Your DPM database.
Best way to check this is by running a query against the DPMDB.
The query: Select ServerName, Domainname from dbo.tbl_AM_Server
returns an overview of all protected servers in the database. It could be that servers are duplicate in the database with their NETBIOS and their FQDN.
If there are any duplicates you should stop protection for these servers and re-add them to DPM. This should resolve the issue with the crashing DPM console
