Unable join workgroup server to newly created AD

Error: The query for SRV record could not be completed









(Note: Above error message was re-produced by stopping the DNS Server service. The error message related to this case would be similar to some extent)

Add SRV records in your DNS server for:
  • _ldap
  • _kerberos
In the following folders:
  • Forward Lookup Zones/Domain_Name/_msdcs/dc/_sites/Default-First-Site-Name/_tcp
  • Forward Lookup Zones/Domain_Name/_msdcs/dc/_tcp


However, this could be avoided as long as the forward lookup zone for the domain is configured as an Active Directory-Integrated Primary.

Alternatively, you can force the registration of all DC-specific DNS records by running 
nltest /DSREGDNS

vMotion error

Error: The vMotion failed because the destination host did not receive data from the source host on the vMotion network. Please check your vMotion network settings and physical network configuration and ensure they are correct.

Make sure the 2 physical adapters of the ESXi hosts are connected to the same network device in the same order. Cisco Discovery Protocal (CDP) must be enabled in the vDS and Cisco switches to retrieve this information.

In the following scenario, the first vmnic of ESXi host 1 is not connected to the same physical switch as the first vmnic of ESXi host 2 (notice the difference in device ID). However, second vmnic of ESXi host 1 and the first vmnic of ESXi host 2 were connected to the same physical switch. vMotion issue was rectified by making sure physical adapters of both ESXi hosts connect to the same switches in the same order.

ESXi host 1:



ESXi host 2:
