Error 1017. Tried Everything

[myp99acct]

Everquest was working for 2 weeks.
Now all of a sudden error 1017 every time. Started a few days ago.

I have:
Followed install instructions perfectly
tried updating router firmware, linksys router
tried turning on/off router firewall
tried turning on/off router uPNP
tried turning on/off router DMZ
tried forwarding all ports
tried bypassing router and directly connecting to PC
antivirus and windows firewall are disabled
Reinstalled EQ
ipconfig /release, ipconfig /renew, ipconfig /flushdns
enabled windows services
turned off router for 5 minutes
disabled a core by going to start menu,run,msconfig,boot.ini,advanced options, /NUMPROC=1

Notes:
- If I take the internet connection wire out of my desktop and plug it into my laptop, I can play on my laptop.
- If I'm playing EQ on my laptop and try to join the server on my desktop, I get booted from EQ on my laptop even though I still get error 1017 on my desktop.
- EQ has always worked on my laptop.
- Both my laptop and desktop are intel dual core CPUs.
- Laptop:XP pro desktop: xp home
- I was also able to set up a windows server that shows up on the login server's account list by following eqemu site's guide, but also cannot connect to it now.
