maybe my answer doesn't hit purposes of this forum but: did you already checked following configuration parameters with VMware Support ?
Then about Operating System:
- Which is OS version of your DC ?
- Did you also try to clean all hidden/orphaned devices:
1. From Command Prompt type: set show_nonpresent_devices = 1 (enter)
2. Then launch Device Manager: devmgmt.msc (enter)
3. From View menu tick "Show hidden devices" item
4. Now you should see orphaned devices (if exist), grayed out: remove those Network cards no more in use.
5. Try to remove and re-add VMXNET3 network adapter
Note: Try also to update VMXNET3 driver from Device Manager manually (Folder: %ProgramFiles%\VMware\VMware Tools\Drivers\vmxnet3)
