Hello Everyone...
First and foremost, Thank for your responses , and Prior to posting this question I have spent some time researching.
I am deploying vCSA to and already up and running infrastructure that is currently using vCenter Server for Windows.
I'm able to deploy the vCSA but when it comes time to Join to the Domain it gives me the following error:
*** ERROR ***
Error: DNS_ERROR_BAD_PACKET [code 0x0000251e]
The "Join active directory" operation failed for the entity with the following error message.
A bad packet was received from a DNS server. Potentially the requested address does not exist
***** Things that I have done ****
Verified the DCs A and PTR records in DNS for both ESXi and vCSA
Set DC, ESXi, and vCSA to use the same NTP server
/etc/resolv.conf
domain domain.tld
search domain.tld
nameserver <ip address of domain DNS server>
Enabled SMB2 on vCSA
