    MDAC Error - Error #91 - Cannot open SWDiscovery.cfg

      Hi there,

       

      can someone tell me why this file refuses to open?  I have been getting the following error when trying to call up the IP Network Browser:

       Error #91
      Cannot open SWDiscovery.cfg

      This file must exists in order for this program to operate.

      Object variable or With block variable not set

       I have since installed MDAC 2.6 from the MS website with no change.

       Any idea's on what I can do to cure this?

       

      Thanks,

           Oqtoe - either the file is missing or corrupted.  If the file is missing, you can run a re-install / replair to replace it, otherwise, you will need to find the file (usually in %Program files%\SolarWinds\Engineer's Toolset), delete it, then run a re-install / repair of the Toolset.
