Windows 7 & XP Networking Problem

I have two PCs in my room connected to a Linksys router, both had Windows 7 on them and had file sharing enabled through the Homegroup feature. Now I have XP on one PC, and still Windows 7 on the other. I setup the network on my XP PC and had the Windows 7 PC setup properly so that they could network together.

In 'My Network Places' I can see both PC's listed, I can double click the Windows 7 PC from my Windows XP PC and see the folders that I have set to share, but when I double click any of the folders I get an error message saying "\\PC-2\MP3 is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Access is denied.

However, on my Windows 7 PC, I can go to network and browse all of the files I have set to share on the XP PC. So what do I need to do so that I can access the files on my Windows 7 PC on my Windows XP PC?

 

My own PC in "network" sometimes does not show

ok so i did some steps, i did what they said here:

Restarted, PC didn't show, so i had an idea, i stopped this service:





then started it again and immediately my PC appears in the list now. any clues?

why it's on "tigger start"? in the screencap of that article is just on Automatic.

thanks

I only have this as they suggested in that MS post now:

 

Help needed with simple wired network

Step one- Connect all PC's to router, and then the router to the modem. PC's go to router by the ports labeled "1-4" on the back of the router. WAN port goes to router. Power up all network equipment, and then systems.
Step two- Power on the computer connected to port one. Go into router settings at 192.168.0.1 and configure internet, dyndns, firewall, etc.
Step three- Go to "network set up wizard" in windows. (Network places- network set up wizard). The rest is self explanatory.
Step four- right click on each drive and printer you want to share, and then configure sharing preferences. Should be easy enough.
Step five- right click my computer, and the select "map network drive". Using the network address for each piece of hardware you shared, assign network drive letters.

Congratulations, you have a fully operational network. Happy Gaming! *Toast :toast:
