For one of our customers the scenario was:
Windows 11 client with a fresh Install
WIndows Server 2016 as a Domain controller
The client did join the domain but could not update gpo's because coult not access the share under \domain.local\SYSVOL
a "gpupdate /force" from client resulted in a "could not read policy object 'XXXX-YYYY-ecc' "
surfing the network path at \domain.local\SYSVOL resulted in a "denied access" with credential request
Apparently, the solution was to check under the Server side if smb v1 support was still active and then disabling it
first step was to remove the smb1 feature from "Server Manager":
- open server manager app \ Manage \ remove roles and Features \ Features : uncheck SMB 1.0/CIFS File sharing Support
- Reboot the domain controller
second step check with powershell the status of smb v1 protocol
- Get-SmbServerConfiguration | Select EnableSMB1Protocol if the output is True, disable it by the command:
Set-SmbServerConfiguration -EnableSMB1Protocol $false
issuing again the get command shoul result in a False state
Typing againg the "gpupdate /force" on the client side resulted in a positive output with no errors and the SYSVOL was now available to the client operating system.
No action was needed on the client
hope this helps
Cheers
