Chewy, I had the exact same problem and have been racking my brains for
months on this. At first, I thought is was just the "Group Policy - greyed
out Firewall" issue causing my grief. I fixed that (thanks to another
discussion thread); But, it didn't help me in this issue. So, tonight, I
finally found this Discussion Group and I am so very happy! I followed the
steps precisely and IT WORKED!. How cool is that? I really appreciate all
the assistance here. Not sure what caused this to happen in the first
place...as I once had everything working just fine (files being shared
between my desktop and laptops, etc.)....must have been some malware or
something. I run XoftSpy, MS Anti-Spy, and Spybot S&D...I figure between the
three of them, it pretty much catches the culprits. But, I guess there's
sometimes "remnants of distruction" hanging around even after you clean 'em
up. Anyway, just wanted to pass along the message...THANKS a BUNCH!
