I see Mike's post regarding which VM you're rebooting etc, so with that
in mind it may be useful to know that I also have a similar system in
operation and that, with one exception, it runs reasonably well (thus,
one would hope, so should yours :-).
I utilise Vbox 6, Win10Pro in a VM, Guacamole 1.0.0 in a VM (Ubuntu
18.04), all hosted on a Mint 19 based box. I've not tried VRDE but the
Win10 desktop direct, or via another Win RDP connection or Guacamole,
performs reasonably well with no connection failures.
The one issue I have is high CPU idle usage (>100%) by the Win10 VM. As
I understand it this is not uncommon with Win10 on Vbox, but there
doesn't appear to be a consistent fix for it at this time (annoyingly).
This does seem to slow down the Win10 operation at times, and it (Win)
has crashed a couple of times, but it doesn't seem to cause any
connection problems per se. The Ubuntu VM, and the Mint box both have
reasonable CPU utilisation.
To carry on with your specific issue - while you don't mention if
you're hosting Guacamole as VM, or natively, and whether it and the Win
VM are on the same host (part of Mike's uncertainty I think), it may be
useful to look at resource utilisation, particularly while refreshing.
Although I don't necessarily expect it to be a the nub of your problem
it's a simple thing to check, just in case it's maxing out and dropping
the connection.
Other things that would be useful to check are:
(1) do you connect to anything else with your Guacamole instance and, if
so, are there any issues with that?
(2) How does a direct Win or Linux client RDP connection to the Win10 VM
perform (ie. not using Guacamole)?
(3) Was your Win10 VM a new install or imported from somewhere else? If
the latter are the network adapter settings correct (this can sometimes
cause issues with Vbox)?
(4) Is there any anti-virus software running on the Win10 VM? If so, try
disabling that to see if for some reason it's objecting and shutting
down the connection.
etc...

Hello everyone.
I was just wondering if any one has experience with remote desktop in
Windows 10 pro.
I am running Windows 10 pro in a VirtualBox VM. I have Guacamole
configured to work with remote desktop but I am frustrated with the
connection. The most reproducible version of this problem is a simple
browser refresh of Guacamole's Windows connection, on reload I get the
error message "The connection has been closed because the server is
taking too long to respond..." The worst part is that I have to
reboot the VM to get it working again. I have Windows configured with
the following settings:
modified registry keys
<https://mangolassi.it/topic/17846/make-windows-10-server-2016-rdp-work-with-guacamole>
ignore cert and security
<http://guacamole.apache.org/doc/gug/configuring-guacamole.html#rdp>
I also have a Linux VM running VNC works much more consistently. And
VRDE <https://www.virtualbox.org/manual/ch07.html#vrde> (VirtualBox's
RDP client) also works consistently.
I see 4 potential solutions to this problem:
* Spend more time trying to configure remote desktop in Windows.
* Install Windows Server (which would have the added benefit of
allowing multiple connections.
* Install and use TightVNC instead of remote desktop (also may allow
multiple connections)
* Switch to purely using VRDE for my Windows connections (most
limiting and hacky feeling solution)
Let me know what you think of these options or if you have another
solution.
Thanks
