We thought we made some progress because we were error free for a couple of days after performing the following:

1) Updated the driver on our NICs to the latest version.

2) Created exceptions on port 8080 for TCP and UDP in the Microsoft firewall (we allow exceptions)

3) Took the items of the connection property down to Client for Microsoft Networks and Internet Protocol.

Went to check in two items to TFS and got the connection error again.
