How to get host name instead of IP in UMP server for ICMP probe?
If the hostname is pingable to the correct IP then, while configuring the url in admin console please provide the host name instead of IP. Please make sure that host name is listed in host file in "c:\windows\System32\Drivers\etc\hosts."
If you have DNS for name resolution then there is no need to add host-names in host file, just give the host name while configuring the url.
