Plain Old NTLM Authentication to a Sharepoint Serv (General questions)

Hi,

I'm trying to find some examples of redirecting a user from one site to a sharepoint site somewhere completely different, but passing credentials so they don't have to login again. I've tried the following code (yes, I know I haven't gotten too far) and I'm getting a 401.2 error message.

[code]
<
dim Http1
set Http1 = Server.CreateObject( WeOnlyDo.wodHttpDLXCom.1 )
with Http1

.Blocking = 1
.AutoRedirect = 1
.MyHostname=
.Authentication = AuthNTLM
.Login = mysiteadministrator
.Password = password
.URL = http://sharepoint.mysite.com
.Get
End With
>
[/code]

Any help would be appreciated, thanks in advance.
