[giobytes]

i have win xp pro - running on extreme speed cable internet - running mysql 4.0 - Downloaded the patch from sony eq on june 16 - i am running emu 5.7 DR6. I CAN LOG ON AND PLAY ON ANY SERVER ON EMU - I want to set my pc to be a server and also would like to use the same pc to play eq. I load world.exe, it runs beautiful , no errors , so does my boot5zones no errors... OK now i click on my eqgames.exe Patch with the eqhost.txt
[LoginServer]
Host=eqemulator.net:5995
I enter login name and pass word, i go to the server screen - I select my server , highlight it and click play, screen freezes for 20 secs or so, - NOW I'm BACK AT MY LOGIN SCREEN.. I try again enter my info, this time i select different server , i can login and play no problem, well try one more time -- i select my server and get kicked back to my login screen. question 1. anyone know why this happens? 2. can you use the same PC to act as a server and client ? 3. if no and i need a seperate pc for a server, does the server need to have a copy of everquest installed on it? thanks in advance..
