Hi,
I am getting ping request time out. All servers are in Azure on the same VNET and use the same DNS servers. Conditional forwarders are setup in DNS and you can resolve names with nslookup. What is the issue here?

Also if you do net view \\worker02 or tworker02.testtarget.com - getting error "windows cannot access". Check the spelling or name. It might be issue with your network."

I can't execute any powershell remote scripts for the remote machines either. I get this error:
gwmi : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

C:\Windows\system32>ping tworker02

Make sure the Windows Firewall isn't getting in your way here. Turn if off on a server and try again - it will block ping and file sharing by default.
