I am troubleshooting something that sounds very similar.
I am guessing that your DMM and DMP's are on different subnets. Put a lp
top on teh same subnet as the DMP and try pinging it and/or entering it's web interface.
I am finding that many of mine are up and running then just "disappear", and the issue seems to be them losing their default gateway setting. Inmost cases, they do come back online after a half day/day, but not always. A reboot of the DMP usually seems to help as well.
Again, not sure if this is the same, but it sounds very similar.
