SEP problems on SBS 2003

An associate recommended that I use Symantec Endpoint Protection on by SBS 2003 box as local file anti-virus.  I have done this successfully on a couple servers.  On one particular network, I have an Windows Server 2003 R2 box that hosts the Management Console, and I tried installing the SEP on the SBS box.  I first tried it using the unmanaged version of SEP on the SBS box.  The SBS box froze every time I rebooted it, and I had to cold boot it.  I figured it was that it was the unmanaged part that was the problem.  So today I tried to install it using the managed version.  Same problem.  And unfortunately, I didn't document how I uninstalled SEP.

The server freezes during a standard boot, so that doesn't work.  You can't uninstall it in safe mode (you can get to safe mode via F8 during the bootup process just like any regular Windows machine) becuase the installer service isn't running.

In essence, I went into safe mode, went into msconfig and went into the service tab and removed the Symantec options and rebooted.  Then you can go in regular mode and uninstall SEP.  I presume that will work - what I actually did was go into safe mode and go to msconfig and go into diagnostic startup and then enable all Microsoft services.  This sounds easy and logical, but took several hours of troubleshooting.
