Peter,

Not hard to read - I've been reading these CDiag logs for a few months, and I've
memorised the output. Yours was simple. There were no problems at all except
Peter still has ip problems - it can't ping itself, by name, by ip address, or
by local loop (127.0.0.1). But it can "net view" itself. This points to a
firewall problem, or maybe an LSP / Winsock problem.

But how then can Peter "net view" itself. Better yet, how can the other two
ping and "net view" Peter with no problems?? Frequently this sort of problem
might be caused by extra protocols - some folks install IPX/SPX or NetBEUI,
neither of which is routable, and neither is subject to problems caused by
firewalls, though adding protocols just causes more problems. Your protocol
stacks, shown by browstat, are clean on all 3 computers.

Since both AGNES and D7285M1J can ping Peter with no problem, I would bet that
Peter has a problem in its outgoing IP stack.

We will solve this by patience and persistence. And you will need both.

Let's look for an LSP / Winsock problem first. This won't be easy.

http://support.microsoft.com/?id=811259

If XP RTM or Service Pack 1:
1. Backup and delete the following registry keys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
2. Reboot.
3. Open the network connections folder, right click your network connection, and
click Properties.
4. Click Install | Protocol | Add.
5. Click "Have Disk...", type "\windows\inf" in the box, and click OK.
6. Click "Internet Protocol (TCP/IP)", then click OK.
7. Reboot.

If XP SP2:
1. Start - Run - "cmd".
2. Type "netsh winsock reset catalog" into the command window.

Give LSP-Fix <http://www.cexx.org/lspfix.htm>, WinsockFix
<http://www.tacktech.com/display.cfm?ttid=257>, or WinsockXPFix
<http://www.spychecker.com/program/winsockxpfix.html> a shot.

If no help yet, reset TCP/IP.
http://support.microsoft.com/?id=299357

Start - Run - "cmd". Type "netsh int ip reset c:\netsh.txt" into the command
window.

The problem with repairing LSP / Winsock is that it will frequently reset and
remove all non-Microsoft components. You may end up re installing the firewall
software. Maybe you should un install it first. Fortunately, Peter is behind
Agnes (Agnes is running ICF / ICS IIRC, and effectively Agnes is a software
based NAT router. So Peter is safe.
