NIS 2010 and home networking

Hi,

 

I have problems with my NIS 2010 and home networking. After battling with the program trying to set firewall exceptions and finally resorting to system clean up and reinstallation, I have finally managed to get workgroup / printer and file sharing between Vista and Seven working, but I still cannot see the computers in Network menu of either of the PCs. I was able to see them when I didn't have any Norton products installed, but now they went missing again. This is rather annoying, as I have the PCs on different floors and need to be able to use printer sharing and scanning effectively, as one is a workstation and media PC and the other is a browsing PC (which is connected to the printer). I'm able to access both PCs from the other by IP or the \\pcname command, but I cannot see them on the network menu (of Windows). I have located and confirmed the problem to be NIS2010 (which is installed on both PCs). I did a clean reinstall after there was a workgroup and network established, and it worked before the install just the way I wanted it to.

 

I'd like to know which exceptions I need to add into the NIS2010 (firewall?) to allow the Network menu and detection tool of Windows to find the computers. I also have a third PC (XP) that I'll be wanting to run in the same network and be able to share files and printers with the two aforementioned (which'll also be running NIS2010).

 

Both PCs are in the same work group, Norton finds eachother, they are trusted on Norton, file and printer sharing is on, protocols are installed. Everything apart from Norton is fine, as they see eachother in Windows without Norton.

 

Thanks for the help in advance,

Raist
