No Internet Access. error 1747. and dependency service or group failed to start

Have a dell inspiron 1545 laptop with vista (build 6002: service pack 2).  Have a wireless network at home.  laptop stopped connecting to the network 2 weeks ago.  when i try i get a message "dependency service or group failed to start".  when i go to manage networks, there are no networks found.  Wired internet access also not working with this laptop. both wireless card (dell wirelss mini card 1397) and ethernet controller say thet are working properly.  2 other laptops in the house are working normally on the network.  Have looked at WLAN AutoConfig and Wired AutoConfig and when i try to start  both get ths message....."Error 1747 Authentication Service is unknown".  One other small thing i noted ...isatap.home not working - message says to download drivers -but not on net so cant)..dont know if this is related.

can you help????  Thanks, Aodhanm.


Just wanted to post that I used the

netsh winsock reset

command to fix this same 1747 Error experienced when trying to manually start WLAN
on a Windows 7 Pro machine.

After a reboot it worked fine.
