:[ERROR]:Mandatory Requester Machine not found. Include it in the request or set the subject of the template to "Supply in request". Abort request

:[ERROR]:prepareRequestData failed. Abort Request

We had a deeper look into the certificate request that is coming to the CA server from windows 2016 server and we could see that the attribute
pwszAttributes is null. But for the request from windows 2012 servers the pwszAttributes attribute has the enrolling server details

pwszAttributes:
cdc:******
rmd:******
ccm:*******
