Hello Andrew Mabuza,
Thank you for posting in Q&A forum.
1.Please check if the problem occurs on one machine or on one user account.
2.Please check if you sign in one problematic machine using one local user account on this machine, then check if there is the same problem.
3.Please check if one test machine is disjoined/removed from the domain, whether there is the same problem.
It sounds like the user is experiencing a login loop issue. Here are some steps that might help troubleshoot it:
1.Check for Typo: Ensure the password being entered is correct and not being mistyped.
2.Safe Mode: Try booting into Safe Mode to see if the issue persists. Safe Mode loads a minimal set of drivers and can help identify if a third-party application or driver is causing the issue.
3.Check Disk Space: Ensure there is enough free space on the system drive. A full disk can cause login issues.
4.Corrupt Profile: The user profile might be corrupt. You can create a new user profile to see if the new profile can log in without issues.
5.Check for Updates: Sometimes system updates can resolve such issues.
6.Check for Malware: Malware can sometimes cause login issues. Run a malware scan using a trusted antivirus program.
7.Check System Files: Corrupt system files can cause this issue.
Run system file checker tools: open Command Prompt as an administrator, and use the following command: sfc /scannow
8.Reset Password: Sometimes resetting the password can resolve login issues.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
