Hello! As my Windows troubleshooting routine did not solve anything, I start to suspect the interaction with the Domain Controller (UCS 5.0-4) as the cause for the following issue on serveral virtualized systems:
- Starting Windows system components (cmd.exe, services.msc…) “as administrator” via a shortcut (start menu, search, taskbar) is not possible: I get two different errors (see below) when the UAC prompt should appear.
- Starting the same tools not “as administrator” works fine.
- Starting the same tools directly (e.g. right click on ‘C:\Windows\System32\cmd.exe’ → “Run as Administrator”) works, too.
- In Windows “safe mode”, the links work fine when run “as administrator”.
- The above is true for users with and without administrative privileges.
- when [Ctrl]+[Shift]-clicking an a shortcut pinned to the task bar: “This File Does Not Have an App Associated With It.”
- when running from the start menu (with [Ctrl]+[Shift]-clicking as well as with rightclick → “Run as Administrator”): “Error code: 0x800704b3 / The specified network path was not accepted by any network service provider.”
- no entries in the Windows “Event Viewer”
- Windows 10 VM with latest patches (with and without optional KB5028244 / OS Build 19045.3271)
- virtualized with VirtualBox 6.1 on Ubuntu 20.04 hosts.
- Windows has not been activated by the customer, although the systems are virtualized on their original hardware
- domain managed by UCS Version 5.0-4 errata771
So far I did, without any success:
- ‘sfc /scannow’ (some errors found and fixed, but not the one described above)
- ‘dism’ Cleanup-Image procedure (no errors found)
- restore older Snapshot of VM
- setup of a new Windows 10 VM within a new disk image / container
- latest UCS patches (5.0-4 errata753 → 5.0-4 errata771)
Thanks in advance for any hints!
