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

 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.

HTH,

Greg
