Windows cannot access (insert computer name)__Please check spelling or there may be a problem with your network.

I am networking some new windows 7 machines to a pre-existing network with both Vista and XP computers already on it. I have set it up as a work network and opened the ports in our McAfee firewall that windows recommends. However while the older OS machines can access the windows 7 computers and  the win 7 computers can access the older OS, the windows 7 machines cannot access each other.

The computers show up on the network but when they try to gain access an error message pops up. I've even tried to uninstall McAfee but the problem persists. What is the problem?

hey Jessi9,

dont know if you figured it out yet. i just installed windows 7 ultimate 64-bit 2 days ago and have been pulling my hair out over the same issue. everything seems to be configured correctly, right? i ended up staring at my network adapter setting for some time and realized the rest of my computers are not using TCP/IPv6, everything else is using v4.


So go to your network card settings, scroll down the items and UNCHECK "Internet Protocol Version 6 (TCP/IPv6). Then click on Version 4 -> properties -> advanced -> WINS -> Make sure that the following is enabled, "Enable NetBIOS over TCP/IP.

your computers show up now??


*also, sorry for proposing the previous post as an answer, i clicked it in error, and there is no way to undue it.
