One way connection
 

Recently a friend and I have tried using LW direct connection feature. Here is the problem:

He can view and download my files, but I can only view his files. When I try to download files from him, I get "waiting on busy hosts". Both of us have a cable internet connection running on Windows XP. Any help would be greatly apprciated. Thanks

Sounds like your friends end, His firewall is not configured correctly
to allow LimeWire full access.

Ps. Whats his setup

He has his firewall off. He uses Mcafee firewall and anti-virus.

Do you mean he has his windows firewall Off, and is using Mcafee firewall
at the moment.
Or Both off

Ps.Your friend may have his uploads set to high all so.
Dose ither of you see a brick wall in front of the globe at the bottom left corner of L/W

Do either of you see a brick wall in front of the blue world icon at the bottom of LW's interface? Sample image

And can you both see your own ip address listed above the direct connect search box? Whoever can't see it has a firewall problem.

We have tried it with McAfee on and off. Windows firewall is off. Also have tried it with no firewall or anti-virus apps running. I see the brick wall. I run Norton anti-virus with Black Ice.

Black Ice ?
You must give full access to LimeWire in norton, Opions/Norton Anti Virus/
Internet Worm Protection/Program Control, Give LimeWire Full access
Just shout if that dont fix it.
Peace.

I don't know what black ice is. :D Then it may be your connection device. What brand & model of modem/router do you have?

Black Ice is by Internet Security Systems. I checked Norton and changed it to allow 2-way traffic from LW. Thanks for the info, we will try it later.

P.S. I have no problem downloading files from a search or browsing and downloading from a host that is downloading from me.

Ok
Good Luck, Shout if it did'nt work.
Peace.
