Unable to share network, unable to start ICS

Hi,

I have win7 on my laptop. I am using wireless connection. When I

tried to share wireless connection with virtual network adapter it gives

me an error as unable to start ICS because of dependencies. I tried to

start those dependend serivces.

I was able to start following dependend services :

Application Layer Gateway Service

Network Connections

Network Location Awareness (NLA)

Plug And Play

Remote Procedure Call (RPC)

Telephony

But I could not start the following services :

Remote Access Auto Connection Manager

Remote Access Connection Manager.

Also pls tell me how exactly this sharing works?

Thanks in advance.
