Server 2012 R2 VM RDP Access Logging in Super Slow

So this VM was migrated out of Hyper-V and into XenServer, as I recall it, accessing this server was always super slow even on Hyper-V using HVM.
I'd like to try and resolve the issue, as now even our beloved MSP has said it's taking forever.
Performance on the Hypervisor is well within tolerances, same for the Guest.
Any ideas what might cause a slow console / RDP access session to a Server 2012 R2 VM?
XenServer console is also slow?
-
Is the console slow only? Or both console and in-VM RDP slow?
-
Correct, when attempting to access the VM.
-
Have you tried logging in with a local account?
-
Just getting to "login" to the server is slow. Things pick backup once your in.
-
So the issue is a slow login, not RDP slowness?
-
@scottalanmiller, Correct
-
The long login was present on HyperV as well, but it seems to be just as bad on XenServer.
I'm monitoring the disk usage live ATM and it's spiking up to a lot. 100KB/sec +
-
Try something like Screenconnect to see if bypassing the local login changes things.
-
Any recommendations for a small tool I can use to log out performance output to see what's causing the spike so I can review it via notepad or whatever.
Whatever is causing these spikes, hits and then disappears before I can see what it is.
I'll try screenconnect.

I've used this before to monitor logons to find what is causing issues.
-
It appears to be an issue where anyone attempting to RDP into the VM is passing their Clipboard, printers, etc via the RDP connection.
Specifically the problem appears to be due to the "Portable Device Enumerator Service".
At least from what I can tell at the moment. I'll do some testing at some point today and see what I can figure out.

just wondering - what leads you to this conclusion?
-
It's only upon login that the system runs horribly. Disabling the service and then signing in, the login performance is greatly increased.
-
How could that then affect the XenServer console as those things don't exist there.
-
The XS Console prompts to provide these services for RDP.

To what do they connect because they would be connecting to the XS machine, not to Windows!

I'm not certain but I can only assume that the XenCenter console attempts to pass this information through to the guest VM.

Also this is likely why the login time was taking forever. (IE hey I can't find these devices)

That doesn't make sense to me, RDP isn't to the VM but to XS.
