Support Tip: DPM admin console fails to open and generates error ID 948

~ Dwayne Jackson | Senior Support Escalation Engineer

Hi everyone, Dwayne Jackson here with a quick tip in case you ever run into an issue where the console for System Center 2012 Data Protection Manager (DPM 2012 or DPM 2012 R2) fails to open. First, check to see if your symptoms match any of those listed below.

The first symptom is that you’ll see this error:

Unable to connect to DPM Server Name.Consoto.com (ID: 948)
Verify that the DPM service is running on this computer

You will also see an event logged similar to this one:

Log Name: Application
Source: MSDPM
Date: Date/Time
Event ID: 941
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: DPMServerName.Contoso.com
Description:
The description for Event ID 941 from source MSDPM cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Unable to connect to the DPM database. Make sure that SQL Server is running and that it is configured correctly.
Problem Details:
<FatalServiceError><__System><ID>19</ID><Seq>1</Seq><TimeCreated>1/28/2015 3:22:57 PM</TimeCreated><Source>DpmThreadPool.cs</Source><Line>163</Line><HasError>True</HasError></__System><ExceptionType>SqlException</ExceptionType><ExceptionMessage>Cannot open database "DPMDBNAME" requested by the login. The login failed.
Login failed for user 'NT AUTHORITY\SYSTEM'.</ExceptionMessage><ExceptionDetails>System.Data.SqlClient.SqlException (0x80131904): Cannot open database" DPMDBNAME " requested by the login. The login failed.

Also, if you examine DPMUI0Curr.log you’ll see entries similar to the ones in my example below.

If you encounter these symptoms then the most likely cause is that DPMDB is in SQL Server "Single User Mode".

To fix this, change the database to Multi User Mode by following the steps below.

1. From SQL Management Studio select the DPMDB

2. Right click the DPMDB select Properties

3. From Database properties select Options page

4. Scroll down to State for Restrict Access change from SINGLE_USER to MULTI_USER

5. Select OK

Once this is complete you should be able to open the console successfully.
