Windows 7: One-way file sharing problem between two networked computers

Dear Josh,
Sorry. I mis-spoke...or did not select the correct wording. Both A and B are still on the home network, and both WERE in the HomeGroup. But since I thought the problem might be with B's membership in the HomeGroup, I disconnected it from the HomeGroup and tried to rejoin it. For some reason, B is not being allowed to rejoin the HomeGroup. But, both A and B are of course still on the Home Network. But still, from A, I cannot promptly see folders and transfer files to and from B's C-drive from A. But, everything is possible to and from B's C-drive into A's. I think you are probably correct from a couple of messages ago: something in B...maybe a firewall or the like, is preventing A from ready access to B's folders and files. But, other than A is a Dell and B is an HP, the two devices are virtually identical.
How do I contact chev65?
Thank you for your patience and help, Josh.

I think we can fix the Homegroup problem although the blocked sharing is most likely a problem caused by the anti virus software and may not be fixable without uninstalling the A/V software. The link below describes a special process to uninstall this software from a Windows 7 machine.

Leaving the old Homegroup should be tried first from both machines then create a new one and rejoin if possible.

If leaving or rejoining isn't working then click on the link below and follow directions to remove all files from the Peer Networking folder.
