A friend asked me for help setting up a shared printer on his laptop. The printer is connected to his desktop and shared on the network. The laptop cannot connect to the desktop. I narrowed it down to this, the desktop can ping the laptop, but the laptop cannot ping the desktop. I have been out of IT too long to remember all the steps I could take. The laptop is winxp home connecting on wifi and the desktop is wired. They can both connect to the internet and are on the same network with the same workgroup. I tried disabling the firewall and antivirus, but no luck. Any suggestions?
