Trouble setting up wireless network between my two computers

I have a desktop running Windows XP Home SP3 and a laptop running Vista Home Premium SP2 and have been trying to get them to network and share files/printer, etc… to no avail.

I have followed the directions on this MS KB File and Printer Sharing in Windows Vista | Microsoft Learn including installing the LLTD Responder on the XP computer but still they are not seeing each other. I suspect this is due to my settings in CIS… but I can’t find the setting. I am running the latest version of CIS v. 5.0.1x

I have a Linksys wireless router.

Any suggestions?

You need to make your local network a trusted zone.

First look up your IP address and subnet mask. In Windows go to Start → Run → cmd → enter → ipconfig → enter → now lookup your IP address and subnet mask.

Second create a zone in My Network Zones (Firewall → Common Tasks). Choose Add → A New Network Zone → fill in a name like My local network → Apply. Now select My Local Network Zone → Add → A new address → choose An IP Address Mask → fill in your local IP something like 192.168.1.x usually and your subnet mask; usually → Apply. Now check and see the new network defined. Exit using Apply.

Now we are going to use the Stealth Ports Wizard to make your local network a trusted network (Firewall → Common Tasks):
Choose “Define a new trusted network and stealth my ports to EVERYONE else” → Next → choose “I would like to trust an existing My Network Zone” → choose your local network zone from the drop down box at the bottom → Finish.

Now check your Global Rules and see your network added.
