Running Server 2019. It's a Primary DC, DNS, and DHCP for my network.
I was trying to update and my update failed. In trying to resolve that, I now have this new error. When I go to the control panel and try to access the Disk Management snapin, it tells me:
C:\Windows\system32\mmc.exe
Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.
If I go to the path directly and run mmc it runs fine. It also does this for C:\Windows\system32\control.exe when trying to change adapter options.
I've run sfc \scannow and it reported no problems. I'm at a loss as to what to do next.
