Update - A few days ago I "closed" my Homegroup, (by 'leaving' homegroup on both PC's). I then started a Workgroup. I was a happy camper until this AM. I got the following when I tried to connect to my wife's PC.
Could this be happening because of a "bad" network adapter? I have checked on Realtek site and they say I have the most current driver.
Thanks for any help.
