i recently installed windows media connection software so i can connect my pc
to my ps3.  i am running media center xp.

now when i try to connect to my pc from our laptop i get the following:

microsoft windows network :  Multiple connections to a server or shared
resource by the same user, using more than one user name, are not allowed.  
disconnect all previous connections to the server or shared resouce and try
again

sounds like it is telling me that the ps3 is connected so i cant with the
laptop until i disconnect that.  i close the wmc, that didnt work, i turned
off ps3, and still dosent work.  can't i make it so all computers and devices
connected can access the main pc at once?

i would not consider myself expert with networking, thought i have been able
to make them without "outside" help, i always seem to have to relearn the
process.
any suggestions?
