Fabio Viola's questions

Just for me to understand more, when I run ipconfig /all on my work laptop, at the beginning of the information I see 3 parameters: Host Name, Primary DNS Suffix and DNS Suffix Search List.

I know the first one is the hostname of my laptop and I know the second one is the name of the domain that my laptop is bound too.

I do not understand the third one: DNS Suffix Search List

Let me give you an example:

Host Name: MyLaptopPC

Primary DNS Suffix: network.ad.companyA.com

DNS Suffix Search List:

network.ad.companyA.com

ad.companyA.com

ad.companyB.com

companyB.com

At my job we have (Quantity: 5) different Windows Domain Controller (DC) where our hosts and servers systems are bound to AD and where our users authenticate with their AD credentials.

I have a specific Windows Server system running SolarWind Network Application and we are having some strange issue with users AD authentication.

After troubleshooting, chatting and talking with the SolarWind Networking Team, they recommend me to have the Windows Server where the SolarWind Application live, to just authenticate to only 1 Domain Controller and not to all 5 of them.

Question, how do I adjust the settings where I can tell a system to only authenticate to a specific Domain Controller (DC) and not to all of them?

So far, I tried to edit the hosts file but no luck, traffic still coming through and I tried to create a custom rule firewall but no luck, traffic still coming through.

Any more ideas?
