Limewire is the hardest network to connect to!
 

faster than kazza that may be true, but limewire is harder to connect to, i connect once every 10-15 tries

nothing is running in the background. yes i have win xp sp 2, but i had this problem before sp2

Any firewalls?

everything is off, i use msconfig 2-4 a week and turn startups off, i defrag alot, i keep my pc in topshape

Clarification: Limewire is not a Network. Gnutella is the network that LW connnects to.
Anyway, have you turned "Connect on start-up" on? That will make LW try and connect when it is launched.
If it doesn't work, try disabling it and manually connecting every time you launch LW.
