They are in &quot;WORKGROUP&quot; or are the workgroup names different? &nbsp;Make them the same name if they aren't.<br />
<br />
Can you ping the XP machine's IP Address?<br />
No router? &nbsp;Just a switch, or is the TWC equipment a router as well?<br />
<br />
Can you do an ipconfig /all on each machine? &nbsp;Verify the gateway is the same on all the machines, and they are part of the same subnet. &nbsp;Post the ipconfig /all responses here.

They are in "WORKGROUP" or are the workgroup names different?  Make them the same name if they aren't.

Can you ping the XP machine's IP Address?
No router?  Just a switch, or is the TWC equipment a router as well?

Can you do an ipconfig /all on each machine?  Verify the gateway is the same on all the machines, and they are part of the same subnet.  Post the ipconfig /all responses here.

A small business near me has Internet supplied by Time Warner Cable business class. That modem feeds a 16 port ethernet switch.<br />
<br />
Four PCs are connected by cable to the switch. Three of them (the 7's) see each other no problem, whether as part of a home group or not. None of them can see the XP machine. They have all been set up as part of a Workgroup (that's what it shows when I go to the computer name dialog). I've turned off firewalls. <br />
<br />
I really just want to access a printer installed via USB on the XP machine. It is shared and works on the XP machine but I can't see the XP machine or its shares no matter what I try.<br />
<br />
Advice?
