During this week I faced an interesting problem. A company in Sweden used DPM to back up their SQL environment. One database that had a recovery model full couldn’t synchronize the log files content to DPM.
On the SQL server side I noticed an error in the event viewer with the event id 5, Active Server Pages. This error occurred at the same time as the backup. To solve this I had to re-register the asp.dll from an elevated command prompt.
Run Regsvr32 asp.dll from an elevated command prompt.
