Two XP computers won't talk to each other

[Peter Gil]

I have two PCs with a Linksys 5 port switch (not
wireless). I was running Win 2K Pro and had no trouble
what-so-ever configuring them to share files, printers
and internet (One was set up as a host using
192.168.0.1,
the other using dynamic IP). I did not change anything
in
the hardware but since I upgraded to Win XP Pro (both
machines) I cannot get either PC to see the other. I
have
run the wizard on both machines numerous times. I have
disabled "Client for Microsoft Networks" and "File and
Printer Sharing" on the Internet connection and
enabled "Netbios over TCP/IP" on the local network
connection
and made sure the firewall is disabled.

When I run IPCONFIG /ALL on the host machine, I get the
following:
C:\Documents and Settings\Peter Gil>ipconfig /all

ipconfig /all on the other computer shows DHCP enabled
with an IP address of 169.254.7.122. The properties
dialog box of the TCP/IP protocol for the network
connection has the "Obtain IP address automatically"
radio button selected. The IP address shown in ipconfig
must be the default address of the NIC. If I select
the "Use the following IP address" radio button and enter
an address in the range 192.169.0.2 to 254 with subnet
mask of 255.255.255.0, I get the following error message
when I try to "View Workgroup Computers": "MSHOME is not
accessible. You may not have permission to use this
network resource. Contact the administrator of the server
to find out if you have access permissions." I have
created several shares that are wide open to anyone on
the network and both computers have the same
administrator account and password.

Please help!
Thanks!

Peter,

the 169.254.... address is an APIPA address that the computer
gives itself when set to obtain the IP address automatically,
but no DHCP server can be reached. This means that the two
computers are not even communicating at a rather low level, as
the ICS host at 102.168.0.1 is a DHCP server.

Please recheck that the firewall is disabled on the other
computer as well. If that's not it, check all connections and
cables, check the lights on the router, and have a look at

I wil check the cables again but, I did not change them,
move them or disconnect them since all was working under
Win2k. The firewall is definitely disabled on both
machines. The lights on both NICs are on steady. The
lights at the switch are all on; including the one
labelled Ful/Col - does this mean collision?

Thanks,
Peter

Peter,

usually collisions are indicated by the light flickering. A
steady light means full duplex, which is good.

The next step is to go through
