Windows Server 2012 R2 Essentials Slow During/After OS Updates

Question

We have a Dell server with the Windows Server 2012 R2 Essentials operating system. The server has worked very well for several years. However, now, when the monthly Windows operating system updates are installed, the server becomes extremely slow. This is true both with the OS update process (takes forever, which was not the case in the past) and with the server speed after the update reboot has been done. Server speed does improve over time after this slowdown. Is this a known problem? Could the cause be the loss of cached memory contents when the server is reset? Or is it possibly a temporary disk drive problem (RAID-1 on server)? It has gotten to the point where we are afraid to install monthly OS updates, due to the marked slowdown.

Sounds like some general problems with the hardware. Might want to run the Dell diagnostic tools to see what shows up.

Answer 3

Thanks, I will try running the Dell diagnostics and see what it indicates.

Answer 4

Do you happen to know how to obtain the Dell online diagnostics? We don't seem to have it, but hopefully it can be downloaded or run directly from the Dell website.

Thanks again.
