symptom:
install ubuntu 7.04 by wubi
when login, a pop-out window said "internal error, failed to initialize HAL". You will also found "no network connection" on the network icon at the systemtray. In addition, you can't open "power management" and "hardware information" in "preference".

solution:
search "hal" in synaptic, you will find the below packages
hal
hal-device-manager
libhal-storage1
libhal1

check the properties of them, you can notice they have 2 versions. !!! force them to the old version. Everything will be OK.

(BTW, I also do a little other changes. I am not sure whether they also have effects but you can try if something goes wrong.
force kdebase-kio-plugins to old version
install hal-cups-utils libopenexr2c2a initscripts)

conclusion
This problem is due to the upgrade of HAL related packages. It seems that this problem just occurs in the systems installed by wubi but not in standard systems. I also encountered other problems (slow system) when upgraded, I am not sure what caused them, ubuntu itself or wubi? So my experience is if your system run well, do not upgrade.
This worked for me Thanks xiang
