Cannot create sql instances using domain accounts

Hello there,

I am new server analyst not familiar much with sql servers. I want to help our DBAs who are telling me that they are unable to create Solarwinds SQL DPA Database instances using domain account.

I am aware is that it’s sql 2016 server.

Domain user does not work but sql server login works to create instances.

These domain accounts that they are trying to create instances with are added as Local admin on this sql server already.

Can someone point me in right direction on how to make these DBA guys able to create instances using domain accounts ?

Thanks in advance !!
