My MOSS environment is a basic farm with one MOSS server & one SQL 2005 server.

The WSS upgrade installed ok.
The Office upgrade installed ok.

I ran the configuration wizard which ran through each step without any problem until step 9 where it failed with the error message below.

Central Administration is still running ok.
My Portal is still running ok.

The upgrade appears to have worked however; the version number against the server in Central Administration is equal to 12.0.0.6219.

This is worrying though - this is an OOB uncustomised MOSS environment in pretty much its most simple form.

Update... (10/01/2008)

Spoke to Microsoft who said - ignore the error message (!!)
