Hi!

I have spent quite a lot of time trying to install the 2010 RC agent on a 
2008 R2 DC, but without success. Here what I have tried:

1) Firewall down - installation from DPM server
2) Firewall down - installation locally - with DPM server as parameter
3) Firewall down - installation locally - no parameter - setdpmserver.exe 
with DPM server as parameter - connect agent on DPM server
4) Firewall up - the posted 3 netsh commands - installation from DPM server 
and locally - none worked

If I install the agent locally, I cannot start the DPMRA service (error = 
element not found). But the dpmra.exe is where it should be.

It cannot be a firewall issue because even if the fw is down, it doesn't work.

I have installed the agent on a 2008 R2 without DC (just a fileserver) 
without problems.

Has anyone a clue what to do?

Thanks for your help guys!

kr,
Andreas

Hello,

Did you check if the following has been applied:

Windows Server 2003 SP1 with Knowledge Base article 940349 
(http://go.microsoft.com/fwlink/?LinkId=99034)


I have a related problem where DPM agents were previously pushed out 
successfully from DPM 2010 RC console to destination machines (shown as 
"OK"). After the DPM server was rebooted (to add storage, patch, etc.), the 
DPM agents appear as "Unavailable" despite trying many times to reconnect.

Does anyone know how to resolve this, short of reinstalling the DPM agent 
and rebooting the destination machines in a productive environment?

Thanks!

Hi,

I suspect this is either a WMI repository corruption or some prerequisite 
installation problem.

Try the following:

a. Uninstall MSXML parser from Add/remove program and retry agent 
installation.

b. Repair WMI repository using the following:

1. Run command prompt as administrator
2. Stop the Windows Management service using "net stop winmgmt".
3. Using Windows Explorer, rename the folder
%windir%\System32\Wbem\Repository. (For example,
%windir%\System32\Wbem\Repository_bad). %windir% represents the path to the
Windows directory, which is typically C:\Windows.
4. Start the windows management service using "net start winmgmt".
5. Rebuild the repository using "winmgmt  /salvagerepository".
6. Run the agent installation again.

If none of the above work please send the agent installation logs present at 
%windir%\temp\msdpm%.log on prodution server to vborra [at] microsoft [dot] 
com. Also let us the error logged in event viewer when you try to start the 
DPMRA service.


Thanks

Hi Andreas,

In the step 3 below
Firewall down - installation locally - no parameter - setdpmserver.exe  with 
DPM server as parameter - connect agent on DPM server

was the agent install succeeded and the setdpmserver failed with unspecified 
error?
