Console error:

Answer 1

Ok now I got this:
127
com.compagny.afprestart
Ligne 2 and ligne 4 of the script command not found thats mean:
serveradmin: command not found
will try to add the full path of the serveradmin command in the script:
#!/bin/bash
/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin stop afp
sleep 2
/Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin start afp
Any better idea ?
thanks !
