LAN problem

I have my roomate networked with my computer through a switch through my PCI NIC (I have an onboard 10/100 for internet just to point that out). For some reason or another, I can't share a folder then he just leech it through my Network Places, I have to go through My Network Places into one of his shared folders, then drop whatever he wants to leech of me into his folder. I have both NetBIOS and IPX/SPX protocols installed on the NIC that he's going through. I don't know what to do at this point--any help with this? Thanks in advance.

Jam it back in, in the dark.

I give him read/write access so that I won't be troubled deleting the file after he's done transferring, at least that's how it used to be. =/

There's nowhere I can't reach.

Free.User - No, it's not a dell:

AMD Sempron 64 3000+
ASUS K8V VIA K8T chipset
WinXP Pro SP2 Corp. Ed

Yeah, File and Printer Sharing is enabled on the NIC he's accessing through. Windows' built-in firewall has never gave me problems before, so I won't turn that off. As far as CMD is concerned, I've never tried that, but I guess that's something to try out in a little bit. Any other suggestions?

This thing is sticky, and I don't like it. I don't appreciate it.

ok, I found the problem. I put up a folder to share on the network and tried to access through Network Places, and it says:

"\\BIGWORM\blah is not accessible. You might have permission to use this network resource. Contact the administrator of this server to fint out if you have access permissions.

The network path was not found."

Thing is, I've given permission dozens upon dozens of times, but to no avail. Anyone familiar with this? Thanks for any help.
