I am networking only two computers at a time. I have one this before using XP. Now I have Windows 7 on the main computer and XP on the other. I have the LLTD update installed on XP machine. I have enabled file and printer sharing on Windows 7 machine. When I connect the two together and ping one machine from the other, no reply is received. I do not even see the other computer on the Workgroup which is the same on both. Where can the problem be and how to fix it?

Are you connecting both machines directly? If so, are you using a crossover cable?
Are both of the computers on the same subnet?
Have you made sure windows firewall is set up correctly/disabled on them?

Yes, I needed to pull out the clip on one end and insert all wires the other way. It used to work on both XP machines.

Yes.

File and Printer Sharing is enabled in both firewalls. Still I cannot ping the other machine.

Is it necessary to have a password for the user accounts in both PCs?

ALso, Machine 1 is Windows 7, Machine 2 is XP. LLTD update installed on XP.

Why not just purchase a Router? Seems like a lot of additional work/troubleshooting to connect two stand alones together.

Same subnet with firewall configured and FPS enabled should be able to see each other.

Do you allow ICMP requests to go through your firewalls?
For XP: Control Panel > Windows Firewall > Advanced Tab > Under ICMP click Settings.
For Win7: control Panel > System and Security > Windows Firewall > Advanced Settings link (left hand side) >

** Then verify your inbound and outbound rules. Just look for Echo Request or ICMPv4 in your rules. I believe its labeled as File and Print Sharing(Echo Request ICMPv4).

If you have enabled File and Print Sharing (FPS) this should check the needed boxes but to make sure something wasnt bugged.

Thanks!

Tweaking the firewall in WIn 7 did it.

Few issues:

I can see 7 machine from the XP one but only the Users folder (whch is shared by default). I have shared other folders and given them read/write permissions from other users but still when I try to access 7 shares from XP, it says I do not hae permissio to access the folder. I am bound to using the Users folder.It did work however and I transferred around 30 GBs.

I can ping XP machine from the 7 as well. But when I try to access its shares, it asks for username/password. I enter my credentials but it still says wrong username/password. I tried modifying settings in Win 7 to use 40 - 56 bit encryption instead of 128 bit but that did not help.

Still thanks for making the network function.
