Another good idea is to backup the server before applying any updates or service packs, or take a Virtual Machine Snapshot, if you are using a VM. We will discuss the process of applying updates or service packs later in this chapter. Preparing your server Before starting the installation, some tasks need to be completed to prepare the server. First, make sure you have installed the Network Cards and configured their settings. Even if your network has a DHCP server, it is imperative that the server is assigned a static IP address manually.

The reason for this is that during setup, the TMG Firewall may block your connectivity either temporarily or permanently. When you install UAG remotely, a special access rule is created to allow access to the computer you installed from, but when installing locally, this does not happen. In this case, after the TMG service starts, you will not be able to connect to your UAG server using remote desktop. To allow your computer access at this point and going forward, you need to add your computer to the list of Remote Management Computers on TMG.
