How to use FLTMC.exe to load and unload the evfilter mini-filter driver for Enterprise Vault (EV) for File System Archiving (FSA).

Solution

The FLTMC.exe command is run from a cmd prompt on the Windows file server.  The syntax is as follows:
 
  • To unload the EvFilter driver:

    Fltmc unload EvFilter
     
  • To load the EvFilter driver:

    Fltmc load EvFilter
     
  • To view all instances of loaded drivers: 

    Fltmc instances
     
  • To attach the driver to a specific volume:

    Fltmc attach EvFilter C:
     
  • To detach the driver from a specific volume:

    Fltmc detach EvFilter C:  
     

Note:   The Enterprise Vault services on the file server should be restarted after unloading and reloading the filter driver. 

For troubleshooting purposes the results can be saved to a text file. The syntax would be the same as above but adding > [File name and path]

i.e.: Fltmc instances > C:\FilterInstance.log
