A minute or two

I assumed so. Our secondary domain controller responds fast. So, I suspect something local to that specific one.

No, nothing specific was configured on any of them.

In either case the VM can be RAM-starved; the first case with not enough allocated to support all the processes and services, the latter because the admin cuts its allocation down to the bare minimum (e.g. under 1GB) so there's nothing left for profiles when someone logs on remotely. If the VM gets starved for RAM it will page to disk, which is slow

When it happened, I would say this arrives at the same time I have three errors:
1. The Smart Card Device Enumeration Service service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion.
2. A timeout (30000 milliseconds) was reached while waiting for a transaction response from the ScDeviceEnum service.
3. A timeout (30000 milliseconds) was reached while waiting for a transaction response from the UmRdpService service.
We will check on that.
Thanks
