Hi Everyone,
I upgraded our Sophos server to Endpoint 10 and Enterprise Console 5.1 a few weeks ago. I was using the recommended software subscription which automatically switched to 10 with the upgrade. We only use anti-virus and do not install any other components.
Shortly after the upgrade, many of our Windows 7 users (all SP1, x64) began complaining that when they started their computers and logged in, they were shown a Windows error stating "Windows has encountered a critical error and must restart". It gives a 1 minute countdown and then restarts the computer. This sometimes doesn't happen, other times it happens 5 times in a row.
We narrowed the cause down to Sophos. We uninstalled Sophos which stopped the messages. Has anyone seen this occur? The Windows event log shows errors for services.exe related to ntdll.dll which causes the forced reboot.
When trying to re-deploy Sophos to the computers, we receive an error in the EC that the supplied username/password for installing aren't valid (even though they are and work fine for new installs). For now I've switched the software subscription back to 9 which has downgraded everyone and stopped the reboots. I was also able to re-deploy to the computers I previously could not.
Any ideas here? I've emailed Sophos support without any response. Hoping we can figure something out and switch back to 10.
Thanks!
