After discovering errors with WSUS I have executed repair procedures stated for SBS 2008 via Repair DVD #2.
Whe the product tries to re-install it states the same error with SP1 version (on repair DVD) or with SP2 downloaded from Microsoft.
The error seems to be related to SQL.
After lots of search and no solution I have decided to remove WSUS 3 to re-install.
The error is the same.
Some help is really needed.
Kind regards and Thanks in advance
