I got a refurb 500gig Time Capsule for Christmas, and was able to set it up fine with my iMac, but when I tried to set it up with my Macbook Pro that I use through school it wouldn't show up/mount via wifi or USB. When I tried with my moms Macbook just to see, hers sees it fine. I have a feeling its something to do with the image the school uses on the machines, but when I emailed IT, they said "Typically the images that are set up for each program are just a collaboration of programs required for you to complete course work in your specific program. There are no specific permissions turned on or off that would not allow you to connect to this device." I had my dad play with the router, but its not the issue because the other two machines can access the Time Capsule with no issues. I can give the Time Capsule its own IP in Airport, and it shows it as connected but still won't show it when it scans to set it up with Time Machine. I can ping the Time Capsule from both the iMac and Macbook Pro. The software has been installed on both machines as well. Any ideas?
