arcpy.Exists working in interactive window but not stand-alone script

I am having trouble with the arcpy.Exists() function in a script to check the existence of a table in a personal geodatabase.   When I test in the ArcToolbox Python window, I get the correct result, True, for a table that exists.   When I use the same commands in a stand-alone script, regardless of how I construct the path string, it always returns False for the table.    I also tested just the geodatabase, and it returns True, so it is not having trouble finding the geodatabase itself.  


Below is the code from the script.   When I run from the interactive window, I just remove the print statement.


import arcpy

print arcpy.Exists("Y:/projects/dnr_svmp2016/db/SVMP_2000_2015_DB.v52_20170803/SVMP_DB_v5.2_20170803_AB.mdb/site_samples")
print arcpy.Exists("Y:\projects\dnr_svmp2016\db\SVMP_2000_2015_DB.v52_20170803\SVMP_DB_v5.2_20170803_AB.mdb\site_samples")
print arcpy.Exists("Y:\\projects\\dnr_svmp2016\\db\\SVMP_2000_2015_DB.v52_20170803\\SVMP_DB_v5.2_20170803_AB.mdb\\site_samples")
print arcpy.Exists("Y:/projects/dnr_svmp2016/db/SVMP_2000_2015_DB.v52_20170803/SVMP_DB_v5.2_20170803_AB.mdb")


This script returns:

I'm hoping that the solution is something very obvious that I am just missing right now!   Thanks for any help.
