XP Peer to Peer woes.

create a user account on the notebook with the same username and password as you use on the desktop. that should do it. you could also try running the network setup wizard...

Don't forget that the accounts must have a password. A NUL password will not work.

Plz check the Guest account is disabled or enabled..and NULL password could be a problem too..

Are theese connected in a local network (at home) or behind a server?

Try these two since the other one didn't help:

1) You have a firewall that is not letting you see the other machine. Try diabling the firewall and seeing if that solves your problem. Then you know you have to configure the firewall.

2) Right click my computer, select manage, services and application, services, and check to see if the services for computer Browser is started

Go to start, run, type in the ip address of the share you want to see ie( \\192.168.1.1 ) and see if the share comes up.

Let's go through a checklist.

1.At a command prompt on both systems,we need to check the ip addresses.Type in ipconfig /all and note the ip addresses.
2.Then try to ping each computer using each others ip addresses (computer A trys to ping computer B address and vice versa).
3.If that works then at the run icon in the start menu type in the ip address of the computer share you want to connect to using this format

(example) \\192.168.1.1 and hit enter

This should bring up the share.If not ,there is a more fundemental problem.

Watch out for xtra spaces in the url

As for what a hosts file is ,if netbios has problems in resolving names of ip addresses ,what you can do is create an ip to name resoltion mechanism similar to DNS called a host file.

ie (mycomputer1 192.168.1.3)

On windows it's called lmhosts

I have had this problem after every MS patch download. Even though it's p2p you need to have one computer designated as host on XP. First, find out your IP address and all settings for your host connection, make sure everything is functional for the host. Write down all protocols. Then go to the client, mostly your laptop and make sure all the protocols are the same for your connection. Make sure the ICF is off on the client. Make sure you can ping both machines. Make sure the names of your pc's are correct in the Network. You can also tell the client computer to FIND the host and establish a connection that way. They are not communicating and it may very well have to do with your connection protocols. Are you sharing an Internet Connection? Can they both share? Or is this just can't network? If it's the latter, then you probably have protocol issues.
