I posted this as a reply on a different thread, but it seems to have not gotten any attention, so I am posting it now as an independent thread.
I am experiencing on multiple machines with Sophos Home installed, the following:
Quasi-random BSOD (tcpip.sys) when browsing certain web pages (using MS Edge).
I have figured out the contributing factors to be:
- Recent Windows (March 2024) "quality" updates.
- Sophos Home installed.
- Virtual Machines (network drivers are in the mix).
Additionally, I am running these virtual machines on ESXi7 and it affects both Windows 10 and Windows 11.
Before writing this post, I tried:
- Upgrading ESXi7 to the latest (March 2024) update: 7.0-U3p.
- Updating virtual NIC drivers.
- Changing type of virtual NICs (e.g., E1000e to VMXNET3).
- Removing the March 2024 Windows updates (only a temporary measure).
After reviewing the crash dumps, I obtained the following information that points to a conflict between Sophos and something else.
- PROCESS_NAME: SophosNtpServi
- FAILURE_BUCKET_ID: AV_vmxnet3!unknown_function
I confirmed that un-installing Sophos Home prevents the problem from occurring.
I further confirmed, immediately before making this new post, that the issue still exists after updating Sophos.
I am able to provide crash dumps if needed.
