Fix DNS issues
If the ping test fails, there are 2 options to resolve DNS issues:

Updating the Host File
Open the file C:\Windows\System32\drivers\etc\hosts as Administrator in a text editor, then add the following line to this file:
10.5.1.115 <CUCMFQDN>
Please replace the "<UCCX FQDN>" with your real server FQDN, for example:
10.5.1.115 CUCM1.lab.test
Save the file. Then try again to ping this name and restart the tool.
