I'm slow but think that it has been figured out.
The following didn't work because the 010003 timestamp was wrong
restore db MyDB from c:\db2_primarybackup taken at 20070201010003
The following worked because I only has one file backed up for the day in question.
restore db MyDB from c:\db2_primarybackup taken at 20070201
However, looking at the file itself provided me with the correct timestamp so the following also works.
restore db MyDB from c:\db2_primarybackup taken at 20070201231503
Thank you very much for the help!!!
