Hi,

Auto-update was so kind to install Windows XP SP2 on my notebook (HP
NX9110). After the update my WiFi settings are totally screwed up.

In Windows XP Pro SP1a I had a preferred connection that was always
connected and worked instantly after powering on. No with SP2 I sometime
have a connection, can not reconnect to my WLAN because Windows can not find
the network (nothing changed, hidden SSID, MAC security, no WEP encryption,
speed forced at 54MBps). Sometimes Windows connects to a WLAN in the
neighbourhood (when my WLAN is not found). When rescanning for networks my
WLAN is not shown or all links are very weak.

I upgraded the NIC driver (built-in Broadcom WiFi adapter). And searched
many possiblities. One thing is that the WZC service is not started.
Whatever I tell to the settings, the service does not start automatically.
When I start the service manually from the MMC or DOS prompt, all of a
sudden most thing work correct (some settings are gone however, but that's a
SP2 issue).

Why does the WZC not start automatically at startup? How to sove this
problem. I restored a backup (image) and reran the update manually with the
same results.
