Troubleshooting
Problem
During the IBM® Rational® Build Forge® installation, it fails with a Microsoft® Windows® authentication error, []Error code 1265[].
Symptom
Build Forge installation fails with the error code: 1265 - The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.
This symptom exhibited by the Build Forge installer is due to a Windows authentication error. The problem is specific to installations using the built-in IBM DB2, which attempts to create a new local user for database access.
Cause
This is caused by a failure of the Windows client to contact its domain controller to validate its group policy and certificate information for the user. This is needed in order for the installer, running as the current logged in user, to create a new local user to access DB2.
Diagnosing The Problem
The application log may show something like these messages:
Automatic certificate enrollment for DOMAIN\user failed to contact the active directory (0x8007054b). The specified domain either does not exist or could not be contacted.
OR
Windows cannot obtain the domain controller name for your computer network. (The specified domain either does not exist or could not be contacted. ). Group Policy processing aborted.
Note: These are is only examples, and the application log should be consulted for more specific details regarding the failure.
Resolving The Problem
Verify that the PDC can be contacted, and that the WINS settings for the host are correct.
WORKAROUNDS:
- Install while logged into a local user account, like Administrator or a local account that is a member of the local administrators group. This will remove the need for a PDC lookup.
- Use an already existing user to connect to DB2. This will also allow for the installation to proceed since no new user will need to be created.
