Hi all,
I have a strange issue with a few user's machines (5 or 6 out of 120) IE11 opens but closes almost instantly. One of the iexplore.exe processes stays running even after the window has closed / crashed out.
We are running Windows 7 Pro (x64). All domain joined and fully patched (via WinUpdate)
This iexplore.exe process cannot be stopped (via Task Manager or forced via CMD). It also prevents the machine from responding to shutdown or restart commands. The only way to turn off the machine once IE11 have been run is to hard reset (ie. hold down the power button or pull the plug).
Interestingly, the iexplore.exe properties box in Task Manager shows the process location as:
C:\Windows\winsxs\wow64_microsoft-windows-i..etexplorer-optional_31bf3856ad364e35_11.2.9600.18738_none_8542ae0bf74c22ed
This lead me to believe it was a broken Windows Update or something (since the lingering process is in the WinSXS folder).
We have Symantec Endpoint Protection 14 installed with no alerts being raised and full scans have found nothing untoward.
When I uninstall Symantec Endpoint Protection 14, IE works fine. This issue only seems to appear when with SEP14 installed.
I found a similar issue was reported on v12.1 in 2015: https://www.symantec.com/connect/forums/ie11-crash...
The resolution in that case was to update the latest definitions but ours are all up to date and IE 11 is still not working.
Any ideas why this is happening and how to resolve the issue?
