Win XP Pro & Win XP Home Do not communicate on home network

[Al]

Here is my basic config and the problem

LinkSys wireless router
2 WinXP Home Dell Computers on network (Workgroup =
My_Network)
1 Win98 SE Compaq Computer on network (Workgroup =
My_Network)
Had another Win98 SE IBM Laptop on network (Domain =
My_Network)

All computers had access to all others and the internet.
Was able to map to various shares on each computer.
Printers attached to one of the XPHome Dells and the
Win98 Compaq could be accessed from any other computer in
the network.

Problem:
Upgraded Laptop to Win XP Professional with Domain =
My_Network

The two XPHome Dells and the Win98 Compaq continue to be
accessable to each other.
ALL Computers have access to the internet.

BUT - the XP Pro Lap computer does not have access to any
other computer on the network nor the printers, and the
xp home and win 98 cannot see the xp pro laptop.

I do not have the option of changing the XP Pro computer
to work on a Workgroup rather than a Domain, since this
computer also attaches to my employers network both
within the proprietary network and via VPN.

Does anyone know of a way to get these computers to talk??

Thanks,

Al

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 firewall
programs while troubleshooting. When un-installing a firewall
program, use the un-install procedure provided by the manufacturer .
Don't use Control Panel | Add or Remove Programs, which might not
completely un-install it.

For more information, see:

Windows XP Internet Connection Firewall
http://www.practicallynetworked.com/sharing/xp/ic_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/sharing/xp/network_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/sharing/troubleshoot/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\Parameters

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".
