DCOM 10028 errors every night

DCOM 10028 errors every night

I have recently migrated PMP from a Windows Server 2003 server to a Windows 2012 R2 Server.

I am getting countless DCOM errors every night. The errors are:
  <System>
    <Provider Name="Microsoft-Windows-DistributedCOM" Guid="{1B562E86-B7AA-4131-BADC-B6F3A001407E}" EventSourceName="DCOM" />

    <Computer>pmpserver.domain.com</Computer>
    <Security UserID="S-1-5-18" />
  </System>
  <EventData>
    <Data Name="param1">N</Data>
    <Data Name="param2">     e90</Data>
    <Data Name="param3">C:\windows\SysWOW64\cscript.exe</Data>

The message in the error is:
DCOM was unable to communicate with the computer N using any of the configured protocols; requested by PID      e90 (C:\windows\SysWOW64\cscript.exe).

The letter N is variable. It can be a IP Address or a host-name. It looks like it's trying to communicate with every host that is in PMP.

This error happens on both my PMP servers.

I have been looking in the General Settings but I can't seem to find a setting that could be the cause of these errors.

Any help would be much appreciated.

Kind regards,
