peer to peer not working correctly

Hi,

My wireless ad hoc (peer to peer) network doesnt function as expected. Both
machines use Windows XP PRO SP1 and same barand Wireless NIC

I have set up the network between two computers to share USB ADSL modem. The
computer with modem can see and access files from the other computer without
problem. But when using the computer without the modem, it can connect to
the internet and use the shared modem without problem but cannot access any
shared files or data from the master PC. When using network browser (in
explorer) it shows both computers but when I try to access the main computer
it gives a warning dialogue say the computer is in accessible and that I may
not have permission to access it.

How can I correct this problem, I cannot find any settings that allow
changing of the permissions to computers on the network.

TIA
Birderman

Have you created identical user accounts on each PC?

1. Permanently disable XP's built-in Internet Connection Firewall on
local area network connections -- it's for use only on a direct modem
connection to the Internet. Disable and un-install all other
firewalls while troubleshooting. Details here:

Windows XP Internet Connection Firewall
http://www.practicallynetworked.com/...c_firewall.htm

2. Use only one protocol for File and Printer Sharing. If the network
needs more than one protocol, unbind File and Printer Sharing from all
but one of them. Details here:

Windows XP Network Protocols
http://www.practicallynetworked.com/..._protocols.htm

3. Make sure that NetBIOS over TCP/IP is enabled on all computers.
Details here:

Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/...hoot/netbt.htm

4. Run "ipconfig /all" on XP and look at the "Node Type" at the
beginning of the output. If it says "Peer-to-Peer" (which should
actually be "Point-to-Point") that's the problem. It means that the
computer only uses a WINS server, which isn't available on a
peer-to-peer network for NetBIOS name resolution.

If that's the case, run the registry editor, open this key:

HLM\System\CurrentControlSet\Services\Netbt\Parame ters

and delete these values if they're present:

NodeType
DhcpNodeType

Reboot, then try network access again.

If that doesn't fix it, open that registry key again, create a DWORD
value called "NodeType", and set it to 1 for "Broadcast" or 4 for
"Mixed".

For details, see these Microsoft Knowledge Base articles:

No, and I have nether had to do this on other peer 2 peer networks that I
have configured.

This problem seems beyond me as I have double and tiple checked all the
settings and cannot find anything amiss or that can be adjusted to limit
access from other users
