Now having completed a full SBS 2008 deployment, I feel I can give some thoughts and a more proper review of the system.
Overall SBS 2008 is a very nice and slick system. There are some nice changes to it from SBS 2003, but there are also some things that you do need to watch out for.
First the positives about it. The install process is very smooth and simple. Really a base preconfigure took an hour of my time and a couple hours to download patches and updates. The help files in the actual SBS console are way better than the help in SBS 2003. They actually explain how to move files and folders such as the user folders to different drives, something you had to look up on the net with SBS 2003. They also have gotten rid of the licensing feature, so while you still need to purchase CALs, you don’t install them directly on the server. The also have one wizard for setting the server IP and Internet connectivity. Also it will try to discover any router/firewall and attempt to allow you to configure it ( I did not test this feature out). Also you can set it up to automatically redirect user folders (i.e. My Documents) to the server with just the check of a box.
Downside though are somewhat more annoyances than anything else. First off, you cannot run the Internet Connection Wizard if there is another DHCP server running on the network (say from a firewall/router). This can be a pain due to hunting down DHCP servers. Also the password policy wizard I found to be incomplete. Considering this was a new network, and I gave users a default password that they were going to change after everything was set up, I had to go through group policy to change the fact that passwords had to be active for more than 2 days before you can change them. This decision was not available in the password policy wizard and did make things a little more difficult until I found the policy and figured out that it had to be set to 0 days and this was after setting it to undefined did not produce the desired result. Finally, my last complaint is updates. Basically that you actually have to tell the update system to search for more than just OS updates. If you don’t it will not find the Exchange, SQL, or other items that are part of SBS 2008 and will need to be updated (not to mention Microsoft trying to force IE8 down our throat by making it a high priority update).
Even with these few minor issues, I think that SBS 2008 is a definite step up from SBS 2003 and one that will be good for many future uses.
