SharePoint Extranet Solutions with ISA Server 2006 – Part 1: Teaser

Over the next few weeks, I plan to publish a series of posts describing how to publish a SharePoint Extranet solution using ISA Server 2006. The Objectives are:

Access and URLs:

• partners use https://extranet.sharepointnotes.local at all times
• internal users use http://extranet.sharepointnotes.local when sitting on the internal, trusted LAN 

Authentication

• Internal users authenticate the corporate AD
• External users authenticate using an AD in the DMZ
• The ISA Server is member of the corporate LAN

URLs 

• The public URL must always be http://extranet.sharepointnotes.local or https://extranet.sharepointnotes.local regardless of what web application / zone the user is redirected to internally

The ingredients include – but are not limited to – the following:

• ISA Server 2006
• Active Directory
• DNS
• Stand-alone Root CA
• Multiple ISA SharePoint Publishing rules
• At least one web application extended to use multiple zones
• Alternate Access Mappings

The inspiration for the series are the following articles:

• What every SharePoint administrator needs to know about Alternate Access Mappings (Part 1 of 3)
• How to use WSS v3 with ADAM for user authentication  

Tag along – it should be good fun

Update: Initially, I wanted to do this series using ADAM, and although ADAM works with MOSS – it doesn’t seem to be supported combined with ISA Server 2006. So we are using a stand-alone Active Directory instead.

ISA Server 2006 Enterprise – Quick Installation Guide

Quick guide to install ISA Server 2006 Enterprise Edition:

Prerequisites:

• Make sure your ISA Server has at least two NICs and that IP addresses, default gateway, DNS, WINS etc are configured correctly. Name one interface Internal and the other External
• Create a user account in Active Directory and grant it local administrative permissions on the ISA Server

1. Login as a domain user with local administrative rights
2. Start the installation
3. Select Install ISA Server 2006
4. On the Welcome Page click Next
5. Accept the terms in the license agreement and click Next
6. Enter User Name, Organization, and Product Serial Number and click Next
7. On the Setup Scenario page select Install both ISA Server and Configuration Storage server and click Next
8. On the Component Selection page keep the default selections and click Next
9. Select Create a new ISA Server enterprise on the Enterprise Installation options page and click Next
10. Click Next when faced with the New Enterprise Warning 
11. On the Internal Network page click Add
12. Click Add Adapter or Add Range to add the IP addresses that are included in the internal network 
13. Click OK and Next 
14. On the Firewall Client Connections page click Next
15. Click Next in the Services Warning page 
16. Finally, click Install. Since we are installing ADAM you might get asked for CD2 of Windows Server 2003 R2
17. Select Invoke ISA Server Management when the wizard closed and click Next

That’s it.  We are now ready to publish SharePoint sites – more on that later!
