When you select a connection profile, but cannot connect to the MySQL server, a window specifying the error will appear (see figure).
Normally, this means that either the credentials you have specified are wrong (wrong username, wrong password), or that you do not have privileges to connect to the MySQL server from the machine where MySQL Administrator runs. You can find more information about that error in the Causes of Access denied Errors section.
However, there might be a network problem that prevents you from connecting to the MySQL server. For that reason, the error dialog provides a
button. Clicking this button will send an ICMP PING request to the host machine where the MySQL server you are trying to connect to runs. If the host machine is available over the network, you will see something like this:Reply from 127.0.0.1: Time=0ms TTL=128 Reply from 127.0.0.1: Time=1ms TTL=128
This would indicate that you are having some other problem. In contrast to this, a network error might show up like this:
Could not resolve hostname remotemachine
