I found my own answer.
For others with this isue the setting is at
\\HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Access\Security\Level
This is a DWORD value set to 1 for low, 2 for medium, and 3 for high.
You can do the same thng for all users on the computer by creating a value
with the same path but in HKEY_LOCAL_MACHINE instead of HKEY_CURRENT_USER.
