I am trying to set up a peer to peer network on 2
workstations, both running XP pro. I thought that this
should be easy. When running the setup wizzard I chose
the option for no internet connection. (For now each
machine connects on its own using a modem).

The problem is that the first machine can access the
second, but the second cannot access the first.

On both machines I have deactivated DHCP and ENABLED
NETBIOS over TCP/IP. Net user guest shows the guest
accounts to be active. The XP firewall is off, as is
zonealarm when I am troubleshooting. Antivirus software
is up to date.

As far as I can tell, both were set up identically. They
have the same workgroup name and unique computer names
and the same users and passwords. From number 1 I can
access folders and print on number 2.

When I ping from computer 2 I can use the name of
computer 1: it finds the IP address but the pings time
out. When I look in "My network places" I sometimes can
see the name of the other computer, sometimes not. Even
when I can see the name of the computer, when I try to
click on it I am told that the workgroup in not
accessible, you might not have permission to use this
resource AND network path not found.

Don't just disable ZoneAlarm while troubleshooting. Un-install it,
too. Then go to Start | Run | Msconfig | Startup and remove any
remnants of it.

Run "ipconfig /all" and look at the "Node Type" at the beginning of
the output. If it says "Peer-to-Peer" (which should be
"Point-to-Point, but Microsoft got it wrong) that's the problem. It
means that the computer only uses a WINS server, which isn't available
on a true 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".

For details, see the section on "NodeType" in this Microsoft Knowledge

When I run ipconfig /all I get Node Type Unknown.

Is that my problem. What to do?

"Unknown" is OK. "Peer-to-Peer" is the one that indicates trouble.
