Time Machine can't back up new MacBookPro

I've used a Time Capsule for network and Time Machine backups for a long time with my iMac, but have just added a MacBook pro, and it connects to the network fine, but I can't get it to work with the Time machine for backups. Keep getting an error " Time Machine could not complete the backup. The backup disk image "/Volumes/Data/My MacBookPro.sparsebundle" could not be accessed (error-1).

The old iMac that used to back up fine also gets an error.

Thanks for any help.

MacBook Pro, Mac OS X (10.7.4)

That is fun Lion bug.. maybe linked to issue with latest firmware in TC as well.

Solution is easy... but annoying.. you need to reboot the TC..

The more sophisticated but in the end just as annoying way is login via airport utility.. use v5 if you still have SL running on the imac.. or download 5.6 if you have only lion now.

The required setting is missing from v6 utility.

Go to manual setup, disk page, disconnect all users.

It will then work.. what seems to be happening is that after a backup one of the computers is holding the TC disk open and not allowing further backups.

See also pondini as there are some other rather unusual causes.

Look at C17.. I refer you to his FAQ and troubleshooting as a whole, as worthwhile skim read and resource.
