I have 3 computers on a LAN each sharing the same internet connection. Computer 1 - Internet Connection+Printer Computer 2+3 - Sharing Internet from Computer 1 Computer 2 and 3 can see each others shared files, but cannot see Computer 1's. Computer 1 is unable to see Computer 2 and 3's files and also has nothing in "Network Places". Computer 2 and 3 can sucessfully share the internet connection from Computer 1, but are unable to share the printer and shared files. Computer 1 can connect to 2 and 3 through remote assistance + tightVNC and they can connect to computer 1 in the same way. All 3 computers are able to ping each other, too. I have disabled Windows Firewall, over the LAN too. Is there anything that may specifically be stopping Computer 1 from sharing the printer and files?

Is computer 1 in the same workgroup as computer 2 and computer 3?

yea it is
