Windows Update - Server 2016 - Problem DeepGuard and Real-Time-Scanning
In the course of the Windows Server 2016 - changeover I increasingly notice that the monthly cumulative updates fail, mostly with this error code 0x800705b4. The error code seems to be a TIMEOUT from Windows Update according to internet research.
There are many workarounds on the internet for troubleshooting.
After some testing I noticed that if I switch off the real-time scanning and the DeepGuard, the update process is completed much faster and successfully.
With activated DeepGuard and real-time scanning the installation usually fails and takes 2-3 hours.
With DeepGuard deactivated and real-time scanning - installation successful and takes 30min.
I have tested this variant with servers that get their Windows updates via the internal WSUS and install the updates normally via the menu function.
However, I have also tried other methods, where I also managed a successful installation of the updates with activated F-Secure.
Starting the Windows tool "sconfig" via an administrative cmd and installing Windows updates via it also led to success, but takes over 5h.
Furthermore, I downloaded the monthly update as a .msu file directly from Microsoft and then installed it manually, which also led to success. This took more than 4 hours and is of course not very effective.
In summary, you can say that F-Secure slows down the Microsoft update process on servers enormously or the update fails because of the timeout.
F-Secure Server Security Premium 12.11 is installed on the servers.
Can you trace or reproduce the above processes and do you have a solution?
Thank you very much for your help.
