Log in stuck at "Authenticate" stage - CreateNamedPipe 231 error

Hello,

At my current client, we are facing some annoying issues with some new VDIs we are setting up.

The VDI seems to be set up and ready to go and it in fact is able to do actions like 'Login', 'Logout' from the Login Agent. It can also run processes as expected.

However, the problems begin when we are logging out after being logged in. If we stay logged out for more than half an hour, when we try to login again, we cannot. When we try to log in at that point, we get stuck at the "Authenticate" code stage (in the object 'Authenticate to windows' in the login process).

It will not log in, we cannot do 'immediate stop' & only by logging in manually and then either signing out do we fix this issue. However, when we wait 30 again after this sign out, the same issue happens all over again.

I have added the logs of Blue Prism when it can't authenticate in attachment. As you can see it keeps on getting the error "BluePrismProvider.cpp(212): CreateNamedPipe failed: 231".

Does anyone have an idea how to solve this? Is this BluePrism related, VDI related, or something else?

As a last remark, note that when the VDI is restarted, exceeding this 30 min window doesn't seem to cause the same issues, so it seems there is a difference between a restarded, fresh vdi and one that is already logged in once.

Thanks for the help!

Kind regards,

Hey All! I have seen this pipe error when customers have a screen saver or lock screen set, and it breaks Login Agent.In some cases, customers will have it set for 15-30 minutes, but it needs to be disabled. Here are some additional GPOs to check. Hopefully this helps! 

Policy Name

Desired Value

Disable or enable software Secure Attention Sequence

Enabled

Interactive logon: Do not require CTRL+ALT+DEL

Enabled

Interactive Login: Message title for users attempted to log on

Empty

Message title for users attempted to log on

Empty

Do not display the lock screen

Enabled

Power saver options - To reduce the required complexity of the processes, screen-locking and screen savers should be disabled.

 

Force specific screen saver

Disabled

Password protect the screen saver

Disabled

Screen saver timeout

Disabled

Enable screen saver

Disabled
