No connection could be made because the target machine actively refused it

Question

Good day,

I am trying to reset my Index because I am getting the "Unable to retrieve topology component health states. This may be because the admin component is not up and running." I've tried resetting from both my App server and web server. I also tried using powershell I get this error "Reset" with "2" argument(s): "Failed to connect to system"

Thanks in Advance!

Answer 1

When topology health start to look bad, and restarting servers doesn't help, I usually end up building a clone of the active failing one. You should try it in your acceptance test environment before making changes to production. Read the script from top to bottom, before you start working your way through it line by line.

Caution! This script shouldn't be run all at once. Edit in your parameters, and use it wisely.
