We're having a rather interesting problem with one of our remote DPs. It was functional under a Secondray Site for almost a year and then about 3 weeks ago, the server name simply disappeared from the System Status in the Console. It remained listed under the Site Management object, and as a valid DP in the packages that had been distributed to it.
So, in troubleshooting this, we removed the DP role, waited 48 hours and re-installed the role. Didn't see anyting hinky in the logs, however this has not solved the issue. When looking at the Distribution Manager log we get the following for just about every package:
Thread Handle = 3868 SMS_DISTRIBUTION_MANAGER 6/10/2015 2:06:13 PM 8844 (0x228C)

This happens for just about every thread. I've checked the WMI permissions, folder permissions, permissions at the drive and permissions on the erver. The Site server name is in the local Admins group which has full control over both the drives and folders, as well as WMI. At this point I'm stumped. I've tried implementing a hotfix I found in a different thread, but when I ran it, it said it wasn't applicable to the server. Any help will be greatly appreciated.
