We are using System Center Endpoint Protection 2012 and recently we have had 2 Windows 2003 servers and 1 Windows 7 workstation start failing definition updates through WSUS. If I click on the update button in Endpoint Protection it comes back with a connection
failed and the following events show up in the application log:
EventType mptelemetry, P1 0x80508007, P2 mpupdateengine, P3 am delta, P4 11.1.4958.0, P5 mpsigstub.exe, P6 4.6.305.0, P7 system center endpoint protection, P8 NIL, P9 NIL, P10 NIL.
and
The description for Event ID ( 5000 ) in Source ( Microsoft Security Client ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the
/AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: mssecurityclient, msseces.exe, 4.6.305.0, 0x80070643, update, cmainwindow__onsignatureupdatestatus, 0, system center endpoint protection,
NIL, NIL, NIL.
The system log also gives me the following errors:

I can download the definition updates manually and they will install fine. WSUS updates will then start working for a few days and then they start failing again. I have uninstalled the System Center client and Endpoint Protection several times and then reinstalled
and still no good. We are not low on memory and there is nothing wrong with our connection.
Does anyone know what could be causing definition updates to fail through WSUS all of the sudden?
