Windows Internal Database broken

[Tone-man 123]

Hi:
I recently had to change the domain and server name of a server that was
hosting WSUS.
WSUS broke, and I tried re-installing it, but the install always failed, and
the log always indicated database issues.

I tried uninstalling and re-installing Windows Internal Database, with still
no luck.

Does anyone know how to repair Windows internal Database, or to completely
wipe it out and start again?

Thanks,

Tony
