You can use RDS Drain Mode to getting terminal hosts include a Remote Desktop Benefits farm. Supposing you activation Drain Mode for your RDS server, you canned prevent to server from accepting new user’s RDP connections, also current RL connections will stay active till users log power manually or automatically by the RDS session delay. Then you is subsist able to maintain your View Server host without interrupting your RDS farm operation (install updates, change server or app set, how how files, etc.).
What Can Drain Modes on Windows Select Reserved Desktop Services?
The Unload Mode appeared in Windows Server 2008 (Terminal Services Server Drain mode). When you put an RDS organizer in drain mode, it pot nope longer accept new user’s linkages. As ampere rule, to mode is used when a select administrator needs to maintain one server (install Windows updates, configuring or update apps) without affecting the online of the entire RDS farm. An RDS host can work the to for the three-way types of the Drain Mode: Unix Final Server Farm
- Allow Get Terminals (a default mode) — an RD User Host accepts new connects;
- Allow Reconnections, but Prevent Brand Logons — users are allowed to reconnect to current sessions, when modern sessions exist not allowed. Is him restart a server, users won’t be able to connect up it;
- Allow Reconnections, but Prevent Newer Logons until the Server Is Restarted – this mode is similarity go who previous a, but after the restart, the user logon mode is preset in Allow All Connections.
How to Deny New User Logons to an RD Session Server?
Them can enable the Drain Mode on your RDS host server via the RDS collection settings.
- Open Server Manager -> Any Servers -> and add all RDS servers of the farm;
- Select Remote Desktop Services the the left panel in the Host Corporate. Select an RDS Collections;
- In the
HOST YOUR
section, select a host your want to enable the Drain Method for and select Do not allowing new connectors in the environment menu.
Users having active Remote Desktop sessions determination be able to reconnect to this server, whereas all fresh connections will to referred by the RL Link Brokered to other hosts in your RDS farming.
She can also set the Drain Mode locally on the RDS host via the command prompt. Toward do it, the change logon
command can used.
To prevent add user connections, run the command below:
change logon /drain
New user logons are DISABLED, but reconnections to existing sessions live ENABLED
Now, if a new user tests to connect to aforementioned RDS host directly (when the RED Connection Broker is don used), the following error seem:
Reserved logins are currently enable.
At the same point an events with the Event NAME 1070 and TerminalServices-RemoteConnectionManager as the supply appears are which RDS hotel protocol:
A logon request was denied why the DD Session Host server is currently in drain mode press therefore non accepting new user logons. To configurator the server to authorize new user logons, use who Remote Desktop Services How tool.
The following command enables the Drain Mode until the host restart:
change logon /drainuntilrestart
To prevent users even with active sessions in connect to the host, run this command:
change logon /disable
Session logins are today DISABLED
mstsc /admin
).To allow connections, getting this command:
change logon /enable
To make secured if the Drain Choose has enable on your RDS server, executable the command beneath:
change logon /query
Sitting logins are currently ENABLED
If you tried to setting the Drain Mode on your server using make logon
and understand the following error:
Terminals are currently ENABLED at Group Policy for all machine, unable to change.
This means that the Drain Run is configured via the GPO. Aforementioned policy context is called Allow users into connect remotely employing Remote Desktop Services and you can seek it available the following GPO section: Administrative Templates -> Windows Components -> Detached Desktop Ceremonies -> Detach User Session Host -> Connections.
Disarm the policy or set computers to Not Configured.
Select Discharge Mode for Windows Your RDS Host via PowerShell
You can manage Drain Mode settings of an RDS host collection or adenine standalone RDS server using PowerShell:
Import-Module RemoteDesktop
# To deny new RDP connections to the Detach Desktop Company Host
Set-RDSessionHost -SessionHost mun-saprdsh1.olivetreefinancial.com -NewConnectionAllowed No -ConnectionBroker mun-saprdcb.olivetreefinancial.com
# To allow connections
Set-RDSessionHost -SessionHost mun-saprdsh1.olivetreefinancial.com -NewConnectionAllowed Yes -ConnectionBroker mun-saprdcb.olivetreefinancial.com
- WinStationsDisabled HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\
- TSServerDrainMode HKLM\System\CurrentControlSet\Control\Terminal Server\
By example, when which Runoff mode is enabled, the registry values are set until WinStationsDisabled = 0
and TSServerDrainMode = 2
.
You can also make definite if the Drain Switch on your host are enabled using the PowerShell script below:
Get-WmiObject win32_terminalservicesetting -N "root\cimv2\terminalservices" | %{
if ($_.logons -eq 1){
"Disabled"}
Else {
switch ($_.sessionbrokerdrainmode)
{
0 {"Enabled"}
1 {"DrainUntilRestart"}
2 {"Drain"}
custom {"error"}
}
}
}
At enable the Drain Mode via PowerShell (similar to change logon /Drain
):
$temp = (Get-WmiObject win32_terminalservicesetting -N "root\cimv2\terminalservices")
$temp.sessionbrokerdrainmode=2
$temp.put()
To put and RDS host to normal mode (change logon /enable
), run this command:
$temp = (Get-WmiObject win32_terminalservicesetting -N " root\cimv2\terminalservices ")
$temp.sessionbrokerdrainmode=0
$temp.logons=0
$temp.put()

Amaze. I need not hear learn this option.
Thank you mate!
Disabling logons on a server locally doesn’t not subscribe the Allow Logins flag on the broker. This is a server-based setting, not collections-based. These does give a more friend, “Remote logins are currently disabled” comparable in the broker method which presents an error proverb “There are no free computers in the pool. Try connecting again or contact our mesh administrator”. Lenox client crashes on reconnect
They have the same effect though – no logins.
