GSEC Windows Services and MS Cloud Practice Question
Exhibit
Refer to the exhibit: {"Error": "Service did not start due to logon failure", "ErrorCode": "0x8007052e", "LogonAccount": "DOMAIN\svc_app", "Machine": "SRV-WEB-01"}You are troubleshooting a service startup failure on a web server. Based on the error code in the exhibit, what is the most likely cause?
⚠ Common exam trap
Candidates often misinterpret authentication error codes as network timeouts or registry corruption, ignoring the explicit logon failure indication provided by the code.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The service account credentials are invalid or locked.
The error code 0x8007052e corresponds to 'Logon failure: unknown user name or bad password'. In the context of Windows services, this indicates that the credentials provided for the service account are either incorrect or the account is locked out in Active Directory. Resolving this requires verifying the account password or checking for account lockouts in the domain controller logs to ensure the service can successfully authenticate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The service account lacks the 'Log on as a service' right.
Why it's wrong here
If the account lacked the specific user right, the error code would typically reflect a privilege issue rather than an authentication failure. Error 0x8007052e specifically points to an incorrect credential or account status, which is a distinct problem from missing local security policy assignments on the host machine.
- ✓
The service account credentials are invalid or locked.
Why this is correct
Error 0x8007052e is the Windows system code for 'Logon failure: unknown user name or bad password'. This confirms that the service manager attempted to authenticate the service account with Active Directory, but the credentials were rejected, likely due to a password mismatch, expired password, or account lockout.
- ✗
The network path to the domain controller is unreachable.
Why it's wrong here
Connectivity issues to the domain controller would typically result in different network-related error codes or timeout errors. Since the system is reporting a specific logon failure, it indicates that the authentication request reached the domain controller but was rejected, rather than failing to reach the authentication service entirely.
- ✗
The service binary is corrupted or missing.
Why it's wrong here
A corrupted binary would typically result in a 'Service failed to start' error unrelated to logon credentials. The presence of a specific logon error code confirms that the service manager successfully located and attempted to execute the service, but failed during the authentication phase with the specified domain account.
