Able to connect to network, but unable to share the printer
Problem: On a peer-to-peer network connection, you are able to connect all the systems, but are unable to share the printer amongst all the systems. For example, you might be able to connect the printer only with the first, fifth and sixth system.
Cause: The File and Printer Sharing service is improperly installed. Solution: Right-click the Network Neighbourhood icon, select Properties, and make sure you have “File and Printer Sharing for Microsoft Networks” installed on the machine to which your printer is connected. Also make sure you enable “Print Sharing” in the “File and Printer Sharing” settings. Then, check that your client PCs have “Client for Microsoft Networks” installed, and are mapping their printer driver to the network port instead of a local port. Also, ensure that you set up the protocols for all the machines properly.
