Have a belkin router
1 destop HP m1160n media center windows xp pro
2 laptops IBM G41, T23 windows xp pro


had my network running without security encryption (only mac addreess filtering) and everything was fine. I enabled the security fearure through the router (WPA-PSK). Now I cannot access my desktop from my laptops, message said I don't have permission. I can access accross the laptops but cannot access the desktop. Can anyone help me figure this out.

I already removed the security center and windows firewall is disabled on all computers, the router has it's own firewall.

You might want to check your administrator settings on all computers to see if something has been changed there. You could also try a system restore to get you back to when everything was working properly without the security feature enabled. I am not the best when it comes to networking but, it is just a thought.
