have a communication issue. When they both traceroute, they go external of my network through the isp just to come back and find one another.
This makes little or no sense to me. When you traceroute what exactly?
If the two machines are having issues communicating then they cannot "go external of my network through the isp just to come back and find one another
If they're clients within the same network, communication between them should never leave that network and if you're doing traceroute from one of them to the other, I can't see how it could go external of your network and return.
In response #1 Guapo clearly asks you to run ipconfig and post the results here. Instead of guessing at the answer, do as you've been asked and let us help you figure it out.
I would highly recommend doing the ipconfig /all command on both computers that are having issues, and again on a third box that isn't. Lable the output appropriately to which computer it's coming from.
