dbus-daemon: Rejected send message...

Each time after boot, I have to wait for proximately 2 minutes before Firefox starts showing any web pages. I believe the delay is caused by the following issue:

Apr  7 21:03:18 linux-kr6c nm-dispatcher.action: Script '/etc/NetworkManager/dispatcher.d/netcontrol_global_hooks' exited with error status 1.
Apr  7 21:03:18 linux-kr6c nm-dispatcher.action: Script '/etc/NetworkManager/dispatcher.d/nfs' exited with error status 2.

Apr  7 21:05:39 linux-kr6c ntpd[3501]: precision = 1.000 usec

I have no idea what my machine is doing, but it seems as nothing is happening between 21:03:18 and 21:05:39. Complete startup log](http://home.tiscali.nl/chaos_and_order.com/openSuSE/network_startup.log) can be found here.

Can someone help me to remove this delay from my startup process?

Thanks,
Boris
