Managed SEP turned into unmanaged
Almost all of the SEP clients managed by my SEPM turned from managed to unmanaged, even when I issue "update policy".
While the SEPM Server was up and running (Ping and Telnet to SEPM ports was ok), I tried to connect to it via remote Desktop, but no response.
I logged on locally and I got an error Message ( " Reporting queued error: faulting application GFValidate.exe, version 11.0.6005.450, faulting module msvcr80.dll, version 8.0.50727.3053, fault address 0x000046b4." ), and some previous messages of ( " Secars Started!" ).
yet the SEPM clients were accessible from the SEPM Server, but seen as unmanaged.
Is there a known root cause for this issue ?
