Can't get mixed OS network to work now.

[Warpspasm]

Just upgraded from XP to 7 at home. We now have one with Vista, one with XP and one with Win7 all connected via wire to a router. When it was two with XP and one with Vista, the network ran fine. Now that I've installed Win7, I can't for the life of me get the Win7 machine on the network. What the heck am I doing wrong?

Are they all on the same workgroup? Right click "Computer" select "Properties" and see if the Workgroup is the same on all three computers.

I actually had the Vista PC show up after fooling around with it for a while. Then, last night I installed 7 on the XP machine and it shows up too. I changed everything over to a "home group" after that, then thought I'd lose the Vista machine because I read all had to be 7 for the "home group" to work. Nope, it's still there!
