Windows Vista PC Backup Error Message

When I try to initiate a full backup of my computer, I received this error message:

the backup application could not start due to an internal error. server execution failed (0x80080005)

Now I know there have been several posts on this, but I have yet to read a solution to the problem. Previously, I had McAfee security suite installed on my computer and have subsequently removed it using their clean uninstall program. I am now running OneCare in its place.

I really need to do a full backup of this computer to ensure I can restore everything back to its original state when (not if) something goes wrong, which within six months it will certainly do.

I'm hoping that someone (Microsoft) will have a solution to this problem.

Start>>Search>>eventvwr.msc

Check error messages in Application and System sections

It can cause by some non-system firewall,antivirus,antimalware...

Okay, but I don't know what I'm looking for.
