Hi,
- Are you able to share the files on the Windows 7 computer with the other computers on the network?
- How have you connected all the computers on the network?
If computers running on different versions of Windows are part of your network, it’s important to use the same workgroup name for all of the computers on your network. This makes it possible for computers running different versions of Windows to detect and
access each other. Remember that the default workgroup name is not the same in all versions of Windows.
To change the workgroup name on a computer running Windows Vista or Windows 7
a. Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.
b. Under Computer name, domain, and workgroup settings, click Change settings.
c. In System Properties, on the Computer Name tab, click Change.
d. In Computer Name/Domain Changes, in Workgroup, type the name of the workgroup you want to use, and then click OK. You will be prompted to restart your computer.
Make sure your firewall allows file and printer sharing; follow the link given to check the settings for the printer to be shared on the network.
