Just seen a wierd error building a clean MOSS VM, running the config wizard afetr install resulting in a config DB being created but errors being logged.
The error refers to the setup routine not being able to set properties within SQL...
After a few minutes googling I found the following post from an MVP: http://hinsua.blogspot.com/2008/03/error-5586-sql-exception-15123.html
This inludes a SQL script to run (which errored due to slightly incorrect syntax), the updating and working script is shown below:
exec
sp_configure
'show advanced options', 1;
GO
RECONFIGURE
WITH
OVERRIDE;
GO
sp_configure
'allow updates', 0;
GO
RECONFIGURE
WITH
OVERRIDE;
GO
Thanks Hector!
