2 of the same machines Home Group

I have 2 of the same Machines, compaq machines running Windows 7 64 bit

I set up a Homegroup and Computer A sees and can access all of Computer B files and documents...but Computer A does not even show up on the Homegroup for Computer B any suggestions would be great


Please help.

I think I got it. there was a 3rd party software installed on one of the systems (Girlfriend) uninstalled it and rebooted and it seemed to work so far.

thanks to those who at least glanced at this topic
