I've recently upgraded the Virtual Hardware to v7 on a group of Provisioned Citrix Servers abd we replaced the NIC with VMXNet3.
These servers boot via DHCP / PXE and therefore have dynamic IP addresses.
The VM's update their DNS records using DDNS via the DHCP Client Service.
The DNS Server allows the guest to update their records.
The VM's running with VMXNet3 no longer send DDNS update requests.
I have performed a network trace comparison of the two, and the VMXNET3 systems simply fail to ever send a DDNS update, even with asked to via ipconfig /registerdns
Systems still running the FLEXIBLE network adapter are performing DDNS correctly.
I've confirmed that the VMXNET3 systems are configured perform DDNS per RSOP -> Computer ->Administrative Templates -> Network -> DNS Client
I'm going to rollback to a different Network driver, but I wanted to see if anyone had seen this and just not posted it.
