Windows 10: Remotedesktop RDP slow/laggy, but only from one specific client to one specific host and...

Hi,im getting really mad at the moment as i got a very weird problem:When i connect from my home laptop to my work PC via RDP into my personal profile server saved user profile its super laggy and unresponsive.If I RDP to the same PC with the domain admin profile no server saved profile its super smooth.Also if I first rdp onto our Terminalserver with domain admin account and then rdp from there to my work PC in the same network with personal profile, its also super smooth.So its just this specific case, form my laptop directly to work PC with personal profile which is laggy but i dont kno

:)

 

Cannot RDP to specific host in specific subnet

This issue is ripping me a new one so I'd really appreciate any help...

Layout:

desk and test are on subnet 1

frank is on subnet 2

vpn is on its own subnet but is passed subnet 1 in the vpn config (handled by router)

all are windows 10

there is full routing between subnets (pass all traffic)

ping works to all hosts, telnet over 3389 works to all hosts, TightVNC works, just rdp is acting up

window firewall is completely off on frank, desk, and test

test is a completely fresh install of windows with all updates

there is no windows domain or anything and all computers are in "WORKGROUP"

rdp testing table:

_from_ -> _to_ _result_

desk -> test yes

desk -> frank no "the logon attempt failed"

frank -> test yes

frank -> desk yes

test -> desk yes

test -> frank no "connects and show lockscreen but says 'username or passowrd is incorrect try again'"

vpn -> desk yes

vpn -> frank yes

vpn -> test yes

keep in mind telnet 3389 works even when rdp doesn't

for some reason frank is the only one that others cannot connect TO (it can connect to others) and for some reason vpn clients are able to connect to frank.

Troubleshooting:

On frank when I attempt to connect from desk/test I sometimes get the following error in frank's event log:

A CredSSP authentication to TERMSRV/<desk/test ip> failed to negotiate a common protocol version. The remote host offered version 4 which is not permitted by Encryption Oracle Remediation.

Microsoft recommends this page:

CredSSP updates for CVE-2018-0886 - Microsoft Support

Based on the above, tried setting to "vulnerable" or whatever, no good.

So I update all windows machines to the latest build so now all rdp clients are version 10.0.17134 and it doesn't help at all except now when test fails to connect to frank it has the same message as desk, that is "the logon attempt failed" and no longers shows
the logon screen as it did previously.

I also tried creating a new account "test" on frank but that got the same error.

IF i connect frank to subnet 1 everything works fine so I think it is simply something to do with that host being on a differnet subnet. Is there anything I can set to allow rdp even though it is in another subnet. How can I rdp to frank and have it remain
in subnet 2? please help!

Slow RDP connection to host machine after updates

Hello,



Thank you for writing to Microsoft Community Forums.



I understand that the RDP connection to the host machine is slow after the updates.



As the issue is related to RDP connection on Virtual Machines, I suggest you to post your query on

TechNet forums, where we have experts who have more knowledge on Virtual Machines and RDP connections.



Hope it helps.
