I've found this on l2divine.com forums.. and I thought its time to pass on
TRYED ONLY WITH L2Walker IG ver. 1.96
WALKER - lineageII Home L2walker Towalker
I did it in this way of order and it works for me.
1.
Download it and do this...
1.1 Unrar every file in your main drive (c:/).
1.2 Find the host file attached and replace ‘yourserverip’ by your server IP.
1.3 Copy (replace or update) your host file adding the lines in ‘this’ host file to
yours located in %systemdir%\drivers\etc\
1.4 Locate and execute the startApache.bat file.
1.5 Delete your gameguard folder inside the system lineage II folder.
For some ppl only this move didn't worked so they did 1 more thing.
THIS PROCES WILL DELETE GG FOREVER
2. Download the files
2.1 Locate the system folder of your LineageII game. (usually C:\Program Files\lineageII\system)
2.2 Locate and make a backup of your engine.dll and core.dll files inside your system folder.
2.3 Copy and REPLACE the files with the ones included in the rar file.
2.4 You are done. Everything is now patched, say goodbye to GG.
Now you can delete the GameGuard folder and GameGuard.des file and they will not come back unless you do a full check in the lineageII.exe. Besides your lineage will run faster than ever. THIS IS TRUE LIKE A **********
PS. This is not my doing/work.. I just passed it foward from some geniuos
Just do this.. its 100% workable :O
