DNN 04.06.02, DMX 04.00.03

We have found today a problem with any File-Types in DMX but we think this problem is located and not by DMX.

We have many uploaded *.exe and also *.zip files in DMX The files is displayed in the Structure btu not displayed by searches as results. We have look any location to locate the Problem and see when we change the OriginalFileName in the Table dbo.DMX.Entries to .msi instead of .exe then lucene have this in the Index. and is also returned in the Search-Results in DMX.

We have also see that the same Effect is by Zip-Archives.

We must make additional Tests to locate the Problem in Detail!

When we found more details about this we post this here for others.

We have make now different  Tests and see the Problem is 100% by Lucene and not by DMX.

We have installed on our System a free Zip-iFilter from Citeknet and make a iisreset then we make a Re-Indexing and the Zip-Archives is now found and Lucene see also the Content of the Files.

We have testet the same with CHM Windows Help Files and here is the same effect and Solution.

Is the needed iFilter for a specified Application not Installed on the Server-System then Lucene return nothing to DMX and you have a empty Search-Result without this specified Files.

We have testet followed free iFilters from citeknet successfull on our System

• Zip-iFilter x64
• CHM-iFilter x64

You can download the free iFilters here (http://www.citeknet.com/)

Information about the Test-System:

• Microsoft Windows 2003 Server EN SP2 x64 Web-System
• Microsoft Windows 2003 Server EN SP2 x64 DB-System
• Microsoft SQL 2005 x64
• DNN 04.06.02
• DMX 04.00.03

Important Information:

We can test only iFilters on x64 System because we use currently only x64 Server-Systems in our Networks, the installation from a 32-Bit System is not a Problem but we must every install all 30 Days a Trial-Version from DMX for the Tests because we need our both licenses for the Test and Production System and the Installation all 30Days for the Trial is to many work for us.

I Hope this Informations helps others.
