I've found a useful bat file that will help you auto restart you logonserver and you world server. Make 2 new notepad files and copy these codes. Save them both as a ".bat" heres the codes

Logonserver
Code:
@ECHO OFF 
CLS 
ECHO WoW Server Started %time:~0,5% %date:~1% 
:SERVERLOOP 
arcemu-logonserver.exe
ECHO Ascent Restarted %time:~0,5% %date:~1% 
ECHO. 
GOTO SERVERLOOP 
:END
World
Code:
@ECHO OFF 
CLS 
ECHO ArcEmu WoW Server Started %time:~0,5% %date:~1% 
:SERVERLOOP 
arcemu-world.exe
ECHO ArcEmu Restarted %time:~0,5% %date:~1% 
ECHO. 
GOTO SERVERLOOP 
:END
