thanks Lycan and smlunatick
I know items one and two are fine.
Can see all pc under mshome group, So thats fine.
Pc2 and 3 can print to the printer that is conneted to pc1, so thats fine.
pc1 can send files to pc 2 and 3 ok so thats fine.
I did uninstall antivius from pc1 and it didnt change but it may not have fully uninstalled
We run all the same antivirus on all three pcs but im not sure how to change for configuration to permit NetBIOS Name Resolution. This can also be known as Internet Worm Protection.
I only run a AntiVirus plus AntiSpyware program.
