Connection to target machine could not be made in a timely fashion

Problem

Actually the error is (note spelling mistake on fashion):

“Connection to target machine could not be made in a timely fasion”

Scenario

One of our DBAs was testing the SQL cluster failover. After he failed over from Node 1 to Node 2, he can no longer bring up SQL Server Configuration Manager (SSCM). Whenever he tried, he will wait for about 30-40 seconds before he gets an error message : Connection to target machine could not be made in a timely fasion

Resolution

This could have been caused by a whole host of things.

In our case, all we had to do was to restart WMI service:

  1. Start > Run > type services.msc and press Enter
  2. Scroll down to Windows Management Instrumentation, right click, restart
