I got this file (layo-west.bat) on my desktop:
@echo off
SET NWN_PATH="D

NeverwinterNights"
SET GLR_PATH="C

Program Files\Gnomish Log Rotator"
cd %NWN_PATH%
start /w nwmain.exe +connect 64.127.106.68:5121 +password PASSWORD_GOES_HERE
cd %GLR_PATH%
glr.exe
You might want to change the paths if you have installed NWN and the gnomish log rotator somewhere else.
And change PASSWORD_GOES_HERE to the layo password
For layo-central.bat and layo-east.bat you just have to change the IP (64.127.106.68:5121) to
64.127.106.69:5121 (central) and 64.127.106.70:5121 (east)
