On a new server installation, we have found a problem with System.Net.WebResponse. Basically, this same setup has worked ok on other servers. So, I guess one specific component is missing.

This is the code:

   ' Get the XML
   ' expC1 Url
   Public Shared Function GetXML(ByVal tcUrl As String) As String
      Dim loReq As System.Net.WebRequest
      Dim lcHtml As String
      loReq = System.Net.WebRequest.Create(tcUrl)
      Dim loResponse As System.Net.WebResponse = loReq.GetResponse()
      Dim loStream As Stream = loResponse.GetResponseStream()
      Dim loStreamReader As StreamReader = New StreamReader(loStream)
      lcHtml = loStreamReader.ReadToEnd()
      Return lcHtml
   End Function

The line:

      Dim loResponse As System.Net.WebResponse = loReq.GetResponse()

causes the problem. Basically, this is within a Web Service. So, once that line is reached, a timeout will occur on the Web Service.
