In a VM - PRTG can't start



Hii!! So, in a VM of Azure, in the "Internet protocol version 4 (TCP/IPv4) Properties" I change the checkbox of "Use the following DNS server addresses" TO "Obtain DNS server address automatically" and then I screwed up!!

Now I can't get access to my PRTG!! but I have internet, Someone knows how can I get the things just like before? I belive that in the:

"Use the following DNS server addresses" had four zeros ("") but I can't remember. If try that? Thanks! And, please, help me!! It's urgent.

PS: Do I need to check the option "validate settings upon exit"??

First of all, I suggest you have a good read of this and familiarise yourself with IPv4 addressing. It will save you a lot of headaches in future if you're going to be dealing with them. https://www.cbtnuggets.com/blog/technology/networking/networking-basics-what-is-ipv4-subnetting

Secondly, "" is not a valid DNS address so I doubt that was what it was previously set to. A common public DNS server to use is Google's, which can be found at and Ideally, if you're in a business environment, you'd want to use the local DNS server if one is available. To obtain the address for this, you will need to speak to the network administrator.

Lastly, no, you do not need to check the "Validate Settings" box. It's only there to comfort those who don't know really know what they're doing.
