I bought a Time Capsule awhile ago but I still haven't been able to fix this issue. In my household, I'm running a PC desktop and a MB Air. The MB Air and Time Capsule work great, but the PC and TC aren't very happy together. The PC is running XP with all the service packs and has two separate logins. I was able to set up one of the logins to view the Hard Drive of the TC, but the other login is having a more difficult time. When trying to map the TC as a Network Drive it asks for a usernam and password which, as far as I can tell, I don't have set up. Has anyone else had this issue and know what username and password I should use? Thanks.
