It keeps on saying \\computername is not accessible. you may not have access to this network resource. This is my first time setting up a network, and I am having a really really hard time. The desktop has XP and Norton 360 and the printer is connected to it. The laptop which has Vista and McAfee. I have done everything. I tried typing in the IP address and it gave me the same message. I tried typing \\computername and it gave me the same message. I did a network map and the desktop was not clickable. I installed the LLTD on the desktop. I did the regedit and changed the value. I tried adding a printer and I typed \\computername\printername and it asked for a username and password. The user account on my desktop has no password. Both computers are in the WORKGROUP workgroup. I have searched endlessly for any answers and they've led me nowhere. Does it have something to do with the firewall or something? I don't know what else to do.

Check the firewall settings on both machines. Ensure that they are set to allow traffic to/from the other PCs MAC address.

How do I do that?

Make sure that Norton 360 is also configured properly for the home network. You can do so by performing the following steps. http://service1.symantec.com/support/norton360.nsf/docid/2006041713504975?OpenDocument&lg=en&ct=aa&seg=hho&src=ap_hot -- Eric Cross Microsoft MVP (Windows Desktop Experience) http://mvp.support.microsoft.com

I tried that already.

Hi, Can the computers ping each other? This kind of issues is usually firewall related. I suggest that you temporarily turn off (uninstall would be better) the firewall/antivirus on both machines and check the result.
