What should be done if a computer account reset does not resolve domain sign-in issues?

If a computer account reset does not resolve domain sign-in issues, having the computer leave and then rejoin the domain is often an effective solution. This process essentially refreshes the relationship between the computer and the domain controller. When a computer is removed from the domain and then added back, it requests a new security identifier (SID) and updates its trust relationship with the domain.

This step is particularly useful when issues arise that are beyond just simple credential discrepancies, as it can clear out corrupt or outdated configurations. It allows for a fresh start in terms of domain permissions and settings, which could be the underlying cause of the sign-in issues.

While resetting the password may seem like a logical step, it may not address deeper issues with the domain relationship. Reinstalling the operating system is usually a more drastic and time-consuming measure that should be reserved for more severe problems. Contacting technical support can provide assistance, but it may not be necessary if the issue can be resolved with the computer's rejoining the domain, making this option the most efficient first step.
