NAV 2010 - System Slow to Boot

I'm running NAV 2010 and my system now takes 5-6 minutes to boot-up.  What setting(s) in Nav2010 might be causing the system to be so slow at boot-up - I checked the Settings, looking for something that might say "scan at startup" but did not see anything.

 

I have a Dell Dim 8300, 4GB memory, WinXP SP3 and plenty of disk space.

 

Any thoughts/suggestions appreciated.
