No network connections available after enter in a domain

Hi.
I'm using the Windows Vista RC1 at home and at work, to give experience in
this two environment. At home, I'm using the 64 bits, with no problems. At
work, I'm using the 32 bits. Until I put my computer in the domain, the
network was working normally. After this, when I restarted the computer, the
network (all: wired, wireless, by modem...) does not work and the tray bar
icon shows the message "Connection Status: unknown - The dependency service
or group failed to start". When I look in the "Services", the service
"Diagnostic Police Service" was not started and when I try to start it, the
follow message is showed: "Windows could not start the Diagnostic Police
Service on Local Computer - Error 5: Access is denied". I had retired my
computer from the domain, but the network connection is still unavailable.

What should I do?

Thanks for all.
