Hello,
There are 2 main causes for showing groups with SID:
- For Built-in groups: Different language on OS vs the default language of the deployment: If the image has a different language than the deployment settings, will be a discrepancy between the Built-In groups (such as Users, Administrator, etc...), to resolve the discrepancy the system only shows the SIDs
- For Domain groups, I'd check the domain controller and problem member both have the static ip address of DC listed for DNS and no others such as router or public DNS. In case this is correct, I will recommend to run the next commands, in order to determine the details about the configuration and domain health.
-On each DC:
Dcdiag /v /c /d /e /s:%computername% >c:\dcdiag.log
repadmin /showrepl >C:\repl.txt
ipconfig /all > C:\dc1.txt
(DC2.txt DC3.txt... etc. if other DC's exist)
-On the problematic machine:
ipconfig /all > C:\problemmember.txt
