Index Query not returning the document properties on Windows server 2008

I have successfully created the catalog, set up the document directory and indexed the documents within my directory. I am having problems with the query not returning the document properties that I would like to see (such as DocTitle, DocAuthor, etc.) for PDF documents. For all other type of documents the query returns the values of the file properties successfully.
