Uninstall ISA Server 2004 from SBS 2003 R2 Premium and change to a single Nic setup

Click to discuss this tutorial in the forums Good old SBS 2003 R2 has to be migrated to a new Windows Server 2012 R2 Essentials with Office 365 as the email solution. Most people have used SBS 2003 R2 Premium with ISA Server 2004 installed.

Before we can continue this migration first step is to uninstall ISA server 2004 and move the SBS 2003 server to a ‘single Nic’ solution. Before you uninstall ISA Server 2004 you must uninstall the ISA Firewall Client software from any client connected to your SBS 2003 R2 server. If you fail to uninstall the Firewall client from your desktops or laptops before you uninstall ISA 2004 from the SBS 2003 R2 it will be very difficult to uninstall the client software. To uninstall the Firewall client run MsiExec.exe /X {199B7F78-69B7-47C5-8D4B-A3ED1391FB6B} /qn. See https://technet.microsoft.com/en-us/library/bb839065.aspx for more details on unattended setup of the ISA Firewall client software.
