Multiple failed logon attempts from "Windows Manager\DWM-#"

Hello,
During a recent network audit, we noticed that Windows 8, and server2012 machines have multiple failed logon attempts from the users "Window Management\DWM-1" (-2 -3 etc). After a bit of research I have found multiple articles on the Desktop Windows Manager hogging resources, or failing to start, but I cannot seem to find anyone who has experienced (or noticed) that these service accounts are creating failed logon attempts. I was hoping someone might be able to shed some light on this.

If you are using McAfee Agent (MA) 4.8 P1 check this link for relevent information.

Because of Desktop Window Manager (DWM-X is the command), Agent-to-Server Connection (ASC) fails on Windows 2012 R2 servers and Windows 8 clients.
NOTE: The -X entry above is a random number for a user that Desktop Windows Manager creates.

Examples:
 window manager\dwm-1
 window manager\dwm-2
 window manager\dwm-3
 window manager\dwm-4

And this one for an update

Thank you for the reply Rob. Unfortunately, we are not using any mcafee products.

Check with Task Manager on one of the systems for Users logged on as dwm-1, dwm-2, dwm-3 etc..
Then do a Clean Boot re applying items until you find out what software is causing the dwm user sessions.

Also on a system with the problems run this command line and check the output

Type or copy/paste the below commands and then press the Enter key after each command.

wevtutil qe application "/q:*[System[(EventID=1000)]]" /rd:true /f:text /c:25 > "%userprofile%\Desktop"\EventID1000.txt

note: check for "Source: Application Error"

wevtutil qe application "/q:*[System[(EventID=1001)]]" /rd:true /f:text /c:25 > "%userprofile%\Desktop"\EventID1001.txt

note: check for "Event Name: AppHang"

Check the files for clues that may lead to a solution to your problem.

Also ensure that you have the latest device drivers installed.
