Upgraded Computer and Lost Netwotk onnection

[Jane]

I upgraded one of three computers on my peer-to-peer network and now nothing
is connected. When I did the upgrade I did a complete reinstall od XP Pro,
renamed the computer and also put in a new username where none had been
before. I didn't change any other configurations.

I know this is not much to go on and will provide any other info needed.
Please tell me how to start to get my network connected again. Thanks!

Ensure that all firewalls are disabled or removed. Make
sure the XP built-in firewall is disabled. It is only for
direct connections to the Internet and must be disabled
on local area networks.

Make sure each machine are on the same subnet mask. If
the subnet mask is different, the computer is effectively
located on a different network. Click Start, Run and
type "cmd" (without quotes) and press ENTER. Type
ipconfig or ipconfig/all. Make sure it is something like
255.255.255.0.

If the subnet mask is different, type ipconfig/release
then type ipconfig/renew if DHCP is present. Otherwise,
you'll need to configure the subnet mask manually.

Also, make sure NetBIOS over TCP/IP are enabled on all
machines. Details here.

Hi Eric,

The subnet mask is OK. I tried to click on the first link you provided and
arrived at this address:
http://www.practicallynetworked.com/sharing/troubleshoot/n which had a 404
error. Next I'll check the NetBIOS over TCP/IP. Thanks for helping.

 

[Jane]

The XP firewall is unchecked and NetBIOS over TCP/IP are enabled on all

machines. Could the name change of the upgraded machine and/or adding a

username be the problem?

Hi Jane,

The last part of the URL went to the next line. Make sure
you copy it all. Here it is again with a shorter URL if
you still are interested.

Hi Jane,

Can you describe the symptoms? If you have the above
mentioned setup correctly and this isn't a hardware
problem, use the same ID and password of the accessed
computer to logon, or try to enable the Guest account in
the XP Pro machine (enable guest account is risky) or
even enable simple file sharing on XP.

I think the network drives are not mapped correctly. Everything else that
I've checked is OK. How can I connect all three network drives? Can we start
with one and then test?
(I did get to the shorter link). Thanks.

 

[Eric]

How did you map the drives? Is this a home or corporate
or school network?

 

[Jane]

I just unmapped them because they weren't connecting. This is a home
network.

 

[Eric]

Are you still having problems? Do you have shared
folders? What happens when you try to access the
computers through My Network Places?
