DHCP Client Not Starting

am having an issue with what i beleive is the DHCP CLIENT service on my
laptop.

None of my network adapters be it wired or wireless are getting DHCP info
from the router automatically. I know its not the router because other
machines using the same router are getting assigned IPS and DHCP info
automatically. If i input settings manually into the adapters then i am able
to access the router and the internet.

I am getting the following error message from Windows Wireless Service:

The dependancy service or group failed to start.

i am unable to view any of the adapters in the network connections area.

Any help would be greatly appreciated.

MS VISTA BUSINESS 32 BIt
3GB RAM
INTEL CORE 2 CPU T7600 2.33 GHZ

I went into services and into the properties of the DHCP client and found
the following:

In the top pane i see 4 items. 3 of them are drivers which dont appear on
the services list when i look for them to make sure they are on.

the 4th one os the nsi service. it appears as off on the services list with
a description of "Failed to read description, error code 998 and when i try
to turn it on it says windows cannot start it on the local computer and gives
this error message:

Error 193: 0xc1

Thanks
