Win 7 64-bit not seeing WinXP Pro 32-bit

Hi guys,

I'm still having problems getting Win7 64-bit to see my laptop WinXP Pro 32-bit. I've done everything you guys have said but to no avail. On the XP if I go to "View workgroup computers" I can see the Win7. But I haven't been able to get Win7 to go the other way. Help please. I have a Linksys router between them n had no problems before I went to Win7(it was Vista). I've followed the instruction in How-to-Geek on setting it up, so u know. But still nothing.
