ID: 43 Details: internal code 0x8099090E agent comm error

[markm75]

I've been testing out replicating data from a file server.. same domain,
same room etc.. gigabit connection (2003 x86 server is the source, while the
DPM is 2003 x64 sp2)..

After about 1hr 4 minutes though.. the agent actually stopped responding for
some reason.. I received:

DPM failed to communicate with the protection agent on server.domain.local
because the agent is not responding (ID: 43 Details: internal code
0x8099090E)

I tried recreating the protection group.. when i went to expand the
networked server.. i get the hour glass.. on the target server's app log i
have :

EventID 85 DPMRA A DPM agent failed to communicate with the DPM service on
targetserver.domain.local.

Both machines are behind a firewall and local, same domain.

are you able to ping the dpm server from the production server?
can you check with the event viewer on the production server and check
whether you can see any error/warning events related to dpmra or net work
communications.

I tried uninstalling the agent, then re-installing.. but its still failing
(I didn't see anything of value on the backup server app logs).. I did see

replica is synchronized with consistency check. (ID: 3163)

I could ping pstdc (the production server with the replica we are trying to
"replicate") just fine from both ends..

That's about all I really see on either end.
I think I mentioned it before.. but this pstdc is also our GC/DC/DNS/DHCP

I'm at a loss as to why it keeps timing out.
Thanks

I'm now getting this error on the production server with the agent as
well:

I'm guessing it's a bit late as it has been several months since the last post, but I just created a blog on this and since the errors are the same, it may be what you are running into.

Bottom line is this same error is coming up when you try to do a restore to a share as opposed to a drive/folder on the target server.

http://blogs.technet.com/b/dpm/archive/2011/03/02/restoring-a-sharepoint-item-with-data-protection-manager-2010-lesson-learned.aspx

The blog is specific to restoring SharePoint, but the idea is the same and likely applies in your situation. You can even verify by checking the dpmra*.errlog on the machine you are restoring to (as noted in the blog).

Hope this helps.

Chris
