Swapping Macs, can't change the image file used for TM to a Time Capsule

Hello ~

I have ten Macs connected to one TimeCapsule (TC) and nine of them work flawlessly performing a TimeMachine (TM) backup. On the one that doesn't work properly, it is a PBP with Leopard 10.5.8, and latest updates. The other Macs are mixed 10.5.x and 10.6.x.

I had a user on the PBP that I had been backing up in the past. I erased the HD and reinstalled the OS, and then created a new account. I wanted to start backing up the new account and have the name of the backup be the new name I put under Sharing Preference (I assume that's where TM gets the name of the backup).

Well, apparently not, the name of the backup is still the old user name from Sharing, and on the old account before the computer was erased.

I have repaired permissions, I have thrown out the TM prefs in Mac HD\Library\Preferences\, I have restarted the computer. So far I can not get the name to change on the sparse image that it copies to, even though TM says the backup completed without error.

So, as it appears the backup is using the same old image file that this Mac had been using, the backup are separate when you go into TimeMachine, they do not seem to access each other's data, and inspecting the contents of the image, the date of the backup file is there for the new user in the old image file.

I really would just like the PBP to stop using the old image file and create it's own image.

Any ideas welcome!

Thanks all
