LinuxQuestions.org - services-admin does not start :S

I don't know how exactly, but somehow my services-admin (System -> Administration -> Services) doesn't start anymore.. I turned a few services off, and suddenly the application crashed and now I can't start it anymore... it says: "You are not allowed to access the system configuration", even if i start it in a root console. The errorlog that i get is:

Code:

GnomeUI-WARNING **: While connecting to session manager:

Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed.



(services-admin:4822): Liboobs-WARNING **: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory

4822: arguments to dbus_connection_add_filter() were incorrect, assertion "connection != NULL" failed in file dbus-connection.c line 4379.

This is normally a bug in some application using the D-Bus library.

4822: arguments to dbus_connection_send_with_reply_and_block() were incorrect, assertion "connection != NULL" failed in file dbus-connection.c line 2873.

This is normally a bug in some application using the D-Bus library.

Who can help me solve this problem? It seems to me that i turned off a service that is required to run services-admin itself, but i don't know how to restart that service (and which service it is). Somehow I also get an HAL error when i startup gnome since this problem. Please help!
