Hi Roger,

I have to admit we're running out of options.

To recap, you have two computers - a desktop and a laptop, connected by
cross-over cable, using APIPA addresses, which are properly assigned to each.
Neither can successfully ping each other by ip address. They have other
connectivity problems, which are higher level. All problems are symmetrical,
and consistent.

You've tested the network adapters, and replaced the network cable (cross-over).
You've updated the drivers for the network adapters.

You've un installed the Norton Personal Firewall, using the intensive
(non-wizard based) Symantec un install procedure. You have Windows Firewall (XP
SP2) enabled on both computers, with the File and Printer Sharing exception
checked.

I presume that you updated CDiag to reflect the new ip address on Rowanlea, on
both computers?

Details to check:
1) Is the Norton firewall part of Norton Internet Security or do you have
Norton Antivirus also? I have had one other person tell me that removal of
Norton Antivirus was necessary in her case, when she had a problem similar to
yours.
2) Disable the Windows Firewall. Ensure that the Windows Firewall (Control
Panel - Administrative Tools - Services) service is Running / Started, with
Startup type Automatic. With SP2, the WF service must be running for network
connectivity.
3) Isolate the problem. Take Compaq to a friends LAN, and see if it will
connect. Get a friend to bring a laptop to Rowanlea, and try to connect.

There are other things we can check when file sharing does not work. But first,
you have to get basic connectivity, with successful pinging by ip address,
working.

Cheers,
Chuck
Paranoia comes from experience - and is not necessarily a bad thing.
