DPM–Deploying DPM Agent to Untrusted or Workgroup Computers

In today’s session I would like to share how you can deploy a DPM agent to a computer that is not part of your domain. 

Computer Name : SC-UNTRUST

DPM Server Name : SC-DPM2010.systemcenter.com

Firstly switch to the computer that is not part of your domain.  Then map to the DPM server using Net Use command.

Next open up the Explorer and browse to the directory of the of the mapping.

Double click on the DPMRA.msi to begin the installation.

Once it’s done, it will displayed as below. Press Enter to close the window.

Open up the command prompt in Administrator mode.  Change the directory to where the DPM agent is installed e.g.

C:\Program Files\Microsoft Data Protection Manager\DPM\bin

Then execute the command to have the computer to have the computer to pre-attach to the designated DPM server with the command :

SetDpmServer.exe –dpmservername SC-DPM2010 –isnondomainserver –username UNTRUST1

The changes will only be in pink colour according to your environment.  As shown above the SC-DPM2010 is where this untrusted computer will be attach to for the DPM backup.  As for the UNTRUST1 is a unique username.  It must be a unique username for each of the untrusted computer that will be supported by the DPM server.  You can use the unique username ONCE in the DPM server.

Once the command is executed, key in the password.  This password is needed when you attach the untrusted server in the DPM.

The end result will be as follow.

Now switch to the DPM server.  Launch the console to begin the installation of the DPM agent.

Select the Computer in a workgroup or untrusted domain and click Next.

Key in the Computer name, the unique username and the password (the same unique username and password that was created in untrusted computer earlier).  Click the Add button, then click Next.

In the Summary screen, click Attach.

Once it’s completed, click Close.

Lastly, remember to check the Password never expires in the local users in both the untrusted computer and also the DPM server.

Thank you and hope this guide is useful.
