internet connection problem after installing windows vista service pack 1

I have windows vista ultimate x64 based os. After i download and instaled service pack 1 my network connections are dissaperd. Everything with hardware is ok, but when i try to create new internet connection it display the message: "the wizard cannot create connection". ps. I have cable modem and i used broadband (PPPoE) conection normaly before installing sp1 PLEASE HELP

hi xxxgamma,

installing new sp1 to vista x64 is kinda annoying. is your previous version of vista x64 an oem or a retail? because if it is an oem, and after installing sp1 somehow it affects the dhcp or the dns.

try this:
press windows logo+r>type cmd>press enter>in the command prompt window type ipconfig/release>enter>type ipconfig/renew

try to observe if the dhcp is available.

thank you very much for reply...
But seems to be problem with RasMan.dll and i dont know how to start this service...
