A Client has had a Time Capsule. It backs up 3 macs for the last 18 months.
One of the macs was upgraded to Snow Leopard. This had to be done using an external drive as the DVD had failed. After this the mac failed to connect to the Time Capsule to run Time Machine backup.
After resetting the Time Capsule and putting the same details into the Time Capsule. The mac then worked.
Unfortunately the other two computers fail to run their time machine backup. They are rejected -"not the correct username or password.
Any help will be much appreciated.
