Microsoft VPN fails to connect clients after moving the VM from ESX 5 to a new ESX 5.5 host

Over the weekend we replaced some aging hardware for a client running 6 servers on a ESX 5 host. We migrated all VMs using Veeam to a new ESX 5.5 host without issue. The only issue that has cropped up and I am scratching my head over is that the Microsoft RAS VPN service is failing to authenticate and connect VPN clients after the move.

We have made no server configuration changes. I migrated it twice two different ways and still have the same issue. I did a quick migration from host to host and I did a complete backup and restore. I even tried setting RAS up on a different server with the same affect.

If I turn the old VM on on the old host it works perfectly. Any ideas?

When you powered on the VMs no questions about Move or Copied?

All services are started that should be started ?

Issue is solved. There is a known issue with ESX 5.5 using the E1000 virtual NIC and PPTP. I created a second NIC using the vmxnet3 type and reconfigured RAS to use it instead. Problem solved. There is a patch for ESX but this was the simplest solution.

You should *ALWAYS* use the VMXNET3 interface!

E1000 is only useful for installations of an OS!

If using PPTP, you also may want to look and investigate as to whether it's a security risk, since it's become vulnerable!

This solution came as part of a VMware support call and quickly resolved the issue.
