Thank you in advance for your help. I installed a linksys router between two computers. One desktop one laptop both run XP Pro(Tablet PC) on laptop. The desktop is LAN the laptop is WLAN. NO INTERNET. They both ping the router. Here is the problem. The desktop will not ping the laptop. The laptop will ping the desktop. When I try to go to the desktop from the laptop I get a username and password login. Where did this come from? (I have never seen this before I have this exact setup at home with the exception of internet, it works great. Just ran the wizard and both computers see each other, share etc.) When I try to go from desktop to laptop I get an error don't have permission to do this. Any Ideas thanks.
