SBS backup Snapin error

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi Group, we get this error message when clicking on the Backup in the SBS
console.

"A problem has occurred with the Manage Small Business Server Backup snap
in. Close and re-open Server Management. If this problem continues, restart
the IIS Admin Service."

We have checked out the IIS 'Windows Authentication' thing

Any ideas greatly received!
