Orchestrator running robot on VM - RDP issues

[mwynnehughes (Matt)]

I’m trying to run a RPA automation on an unattended robot hosted on a VM through Orchestrator v2018.2 but this is failing

The UiPath Robot service on the VM tries to create the RDP session but this is timing out after 120 seconds and is returning the following error.

“A specified logon session does not exist. It may have already been terminated.”

I’m investigating and it looks like this is caused by a legal notice that is displayed after the RDP username/password dialogue.

I’ve temporarily removed the legal notice and UiPath service can now make the RDP connection, resolving the issue.

Has anyone else experienced this issue and managed to resolve this another way?

you can keep the login session alive by using registry value change:

RDP Session Running UiPath Fails On PC Lock

Hi All, Got a strange one which I can’t really put my finger on. I have a virtual server which I use for all sorts, including UiPath. When I set a process running on the virtual server it runs fine, however if I lock my ACTUAL machine the process on the remote server dies. Is there anything anyone is aware of as to why this may be happening? Does a PC lock also put a lock on RDP sessions? Apologies this isn’t particularly UiPath related in a programming sense but wanted to pick some like-min…

UI Path scripts are failing when RDP is disconnected

When RDP is forcefully stoped, Will Orchestrator create Virtual Screen?

Hi Abhishek, Check the Orchestrator FAQ page: [image] The job is actually started by the UiRobot service which is running on the remote machine. Orchestrator only informs that service that it should start a job for a given process and under a the credentials specified in the provisioned robot. If there is already a user session for the provisioned user, the robot will just use that one. Then, after you close the RDP connection, the session is terminated. So the robot execution will crush. Yo…

VM(where robot is running) gets disconnected as soon as I start the execution. What does this message mean?

Hi @hacky You can refer to my post here Note that now, the setting can be set from the Orchestrator (Have it enabled and with the value “False”) [image] Cheers

@Divyashreem,

I guess thats the very same post I have put forth, and also its been solved too.

Well, that being said, I am having another issue now.

I am getting an issue while I am running a bot from an Orchestrator. Like if I am scheduling the bot and stay connected to the RDP server, the execution is successful. But when I am disconnected from the server and trying the run the bot from the orchestrator, I am getting job shown as (Faulted) in orchestrator. The error says ("Executor start process failed, reason System.Runtime.InteropServices.COMException (0x80070520): A specified logon session does not exist. It may already have been terminated. (Exception from HRESULT: 0x80070520)\r\n at UiPath.UiSystemClass.OpenInteractiveWindowsSession(String bstrUser, String bstrPassword, UiOpenSessionFlags nFlags, String bstrApplication, String bstrAppArguments, Int32 nDelayMs, Int32 userToken, UiGenericOptions options)\r\n at UiPath.Core.Setup.OpenInteractiveWindowsSession(String username, String password, OpenSessionFlags flags, String application, String arguments, Int32 userToken, Int32 preferredWidth, Int32 preferredHeight, Int32 preferredDepth, Boolean fontSmoothing)\r\n at UiPath.Service.Impl.Executor.StartProcessInSession(Guid executorInstanceId, String username, String password, SettingsDictionary execSettings, IntPtr userToken)\r\n at UiPath.Service.Impl.Executor.<>c__DisplayClass17_1.<<Start>b__0>d.MoveNext()" )

PLease look into it.

Thanks, ’

have you tried below things,…?

This is the common issue most of us are facing, there are multiple ways to fix this but i have no clue definitely which one will work: i will suggest you for trail and error for all following methods:

• Setting up the rdp RemoteDesktop_SuppressWhenMinimizedin the registry: UI Path scripts are failing when RDP is disconnected

• Use launch Interactive invoke workflow activity while invoking the wokflow.
• Config RDP timeout to create user session.
• Check simulate Type/Windows Type for background automation

else you have to raise issue to Zendesk(UiPath Support)
