I just discovered that I can't connect to my Synology NAS via SMB2/3 anymore when booting from the WinPE rescue media. Pretty sure this had worked in the past already.

Rescue media was created with:
- current Windows 11 Pro build 24H2 26100.3775 (German)
- Hasleo Backup Suite v5.2.2.1

When booting from the created WinPE I get the following error when trying to connect with "net use":
System error 1727, Remote procedure call failed



--

When I try to use the PE network manager, I get these errors instead:
An error occured while starting the TCP/IP Registry Compatibility service (2)! Program will exit now.



--

The program won't exit though and I can try to connect with the same settings I used with "net use". This exits with the following error unfortunately:
The remote procedure call failed and was not executed.

I then recreated the boot media with a more recent Windows 11 test build:
- Windows 11 Pro Canary build 27823.1000
- Hasleo Backup Suite v5.2.2.1

When booting from this test build, everything works as expected as shown in this screenshot:

Booting from a current Windows 11 image and trying to mount the path directly also works (after an initial "wpeinit"):
- Windows 11 image: de-de_windows_11_consumer_editions_version_24h2_updated_april_2025_x64_dvd_ea86301d.iso

So I'm not sure what the problem might be.

Is there a bug in the current Windows 11 version or is something wrong with my Windows 11 build?
Can anyone reproduce these problems?

Thanks!
