strURL = "
var intAnswer = Shell.Popup(strMsg,
POPUP_WAIT,
strTitle,
MB_ICONQUESTION | MB_ICONYESNO );
if (intAnswer == IDYES) {
Shell.Run(strURL);

just save that as xxxx.js and put it in the GP as a logon script for whomever you want to see it. Of course, there is more in there that you need, but just take out what you dont want and change as needed. I got this script from one of my MCSE books.
