Part 1: Infrastructure essentials Blogcast - Getting started

  • Artikel

Part 1. Starting with the basics.... (it does get more complex, a lot more complex, I assure you). In this blogcast, you see an overview of the infrastructure and browse the "emulated" Internet using a client machine connected directly to the Internet. This client is move back to the corporate network and discover that Internet browsing no longer works. ISA Server monitoring is used to diagnose the cause, and find, at least in the first instance, that DNS queries to the Internet are failing. A new rule is created in ISA to allow these DNS queries to be made. Part 2 will solve Internet browsing....

Here's the network diagram as published in yesterday's post where you can also find out more about this blogcast series

If you're interested, here's the real quick and dirty ASP page I used for emulating microsoft.com

<%@ Language=VBScript %>
<HTML>
<BODY>
<p align="center">
Demonstration INTERNET Web Site.<BR>
<I>(In reality, it exists on the Virtual Machine, "INET")</I><BR>

<p align="center">
<B><font color=red size=4 face=arial>Welcome to Microsoft (www.microsoft.com)</B>
<% response.write "<BR>The time is " & now() & "<BR>" %>
</font><BR>
<font face=arial size=4>
<%
response.write "You requested this page from " & request.servervariables("REMOTE_ADDR") & "<BR>"
if request.servervariables("REMOTE_ADDR") <> "72.16.8.252" then
response.write "<BR>You are directly connected to the INTERNET"
else
response.write "<BR>You are connected to the Corporate LAN"
end if

    Hi John,
    Nice blogcast.

    where did the VMRC+ client come from?

    Cheers,

    Jeff

    Thanks Jeff. The tool is internal MSFT only unfortunately. The good thing about using it rather than VMRC is I get the tabs up the top to be able to switch between VMs. Unfortunately, as you'll see if you follow the series as I post them up, I have to stop using it as the load on my laptop with 6 VMs and Media Encoder all running together is too much - I have to switch to a second laptop and use VMRC itself to connect back to my laptop instead. Unfortunately, VMRCPlus doesn't allow me to provide alternate credentials when connecting, unlike VMRC.

    Regards,
    John
