Using Filemon and Regmon to
find security problems with IRM 

Added 8/24/2004 - Article ID: KI0053

For the IRM to successfully fetch data from the data server, a number of security authentications must occur both on the IRM bridge workstation and the RDP Data server.  Depending on which authentication fails a variety of different errors will occur, such as Pervasive Stat 94 or a given IRM web page will not display or the IRM will simply "Hang" (span without showing anything).   

At present Microsoft does not have any utilities or tools to identify where the security failure occurs. This makes troubleshooting security problems from Internet Information Services (IIS) very difficult.  There are some freeware utilities available from www.sysinternals.com which may help.   The Regmon and Filemon utilities are explained here.

Download IRMUtils Folder 

RDP has a variety of Utilities available for download as follows:

  1. Login to the IRM Bridge computer as administrator
  2. Right click the Start button and then left click "Explore" to start Windows Explorer
  3. In the Address bar, enter "FTP.Resortdata.com"
  4. In the right hand panel, right click the "IRMUtils" folder from and select "copy"
  5. In the left hand panel, right click the "C" drive on the IRM server and select "Paste".  This should copy the entire IRMUtils folder from the RDP FTP server to your IRM "C" drive.

Use IRMTOOLS.HTM to test IRM

When troubleshooting the IRM, always use the IRMTOOLS.HTM test program provided by RDP.  See "Using IRMTOOLS.HTM".  Use IRMTools to reproduce the error.

Using REGMON to Determine which Files Cannot be Opened

To use the Regmon utility from www.sysinternals.com to determine which registry entries cannot be opened, proceed as follows;

  1. Login to the IRM Bridge computer as administrator.
  2. Download the IRMUtils folder as described above.
  3. Select | Start | Run | Browse and go to C:\IRMUtils\Regmon.exe. Right click this file and select open. Regmon should start, as follows:

     

  4. Reproduce the error using IRMTOOLS.HTM.  See "Using IRMTOOLS.HTM". Note, for performance reasons it is best to start IRMTools first and get to the point of failure before starting Filemon.
  5. Stop RegMon by clicking the magnifying class Icon.  Then save the file by selecting | File | Save as. Make sure to save the file in the C:\IRMUtils folder as file name "Regmon1.LOG.
  6. Use Notepad to open the file C:\IRMUTILS\FILEMON1.LOG.  Then search for the text "Denied", which should show the security problem:

Note:  If REGMON does not show and "Denied" files, try "FILMON" as described above to test for denied files.  If there are also not any "denied" files this usually means one of two things:

Using FILEMON to Determine which Files Cannot be Opened

To use the Filemon utility from www.sysinternals.com to determine which files cannot be opened, proceed as follows;

  1. Login to the IRM Bridge computer as administrator.
  2. Download the IRMUtils folder as described above.
  3. Select | Start | Run | Browse and go to C:\IRMUtils\Filemon.exe.  Right click this file and select open. Filemon should start, as follows:

     

  4. Reproduce the error using IRMTOOLS.HTM.  See "Using IRMTOOLS.HTM". Note, for performance reasons it is best to start IRMTools first and get to the point of failure before start Filemon.
  5. Stop FileMon by clicking the magnifying class icon.  Then save the file by selecting File | Save as   Make sure to save the file in the C:\IRMTOOLS folder as file name "FILEMON1.LOG as displayed below.

     

     

  6. Use Notepad to open the file C:\IRMUTILS\FILEMON1.LOG.  Then search for the text "Denied", which should show the security problem.

Note:  If FILMON does not show and "Denied" files, try "REGMON" as described above to test the Registry for denied access.  If there are also not any "denied" entries with REGMON, this usually means one of two things:
