iTunes can not find server
I have iTunes match to share my songs to my iPad and iPhone, that works fine.
I have all my songs on a external hard drive connected to my MacBook over wifi at home.
When I take my MacBook to work I can't play music with it, it cannot find the server, but the iPad and iPhone can play all my songs.
How can I play my songs with the computer when I'm not at home. Yes, I can have all my songs on the computer but I do not have the space, therefor I started using iTunes Match to make all my songs reachable everywhere.
Can anyone solve the problem?
THanks
