Internal Server Error

[Stephen]

Hi,
I am using only windows authentication for webpage access (anonymous access
removed) to read a page. I am using this code to read a page and then use
the StreamReader to convert the Page to PDF.

Private Function GetHTML(ByVal sUrl As String) As StreamReader
Dim oReq As HttpWebRequest
Dim oResp As HttpWebResponse = Nothing
Dim lTime As Long = Now.Ticks

oReq = HttpWebRequest.Create(sUrl)
oReq.Credentials = CredentialCache.DefaultCredentials ........ <- I
wonder whether it takes Domain Credentials here
oResp = oReq.GetResponse ........ here <-System.Net.WebException:
The remote server returned an error: (500) Internal Server Error

Dim sr As New StreamReader(oResp.GetResponseStream)
Return sr
End Function

why does this happens? what settings i need to have?
I guess I have all the right permissions set, I even have <identity
impersonate = "true"> if i set it to "false", I get insufficient permissions
message.

Please Advice,
Stephen

you need to switch to Kerberos security and enable credentials forwarding.
