Hi Everbody,

i would like to execute some jobs in the foreground.
This output appears after the execution:
PerformDesktopUnlock->Desktop Unlock/Logon failed in task: Ausführen, reason: Failed to connect to Credential Provider. Pipe result: 0

I erased the certifcates, but in two log-files the error "pipe busy" occurs:

Server_startup.txt
log_serverxxxxx.txt
  server_startup.txt (16kb) downloaded 42 time(s).  log_server20160310.txt (760kb) downloaded 42 time(s).




Thanks for your help...
Regards
Frank

Have you rebooted the server since you made the changes?

Hi Henrik,

thank you for your fast answer.

I reboot the Server several time.

Please open the Server settings in VisualCron Client and verify that UAC is turned off there.

Is your system really 32 bit?

---

No it is 64 bit 2008 R2 SP1.
It is possible to change the dll-reference?

You could delete the file, copy the x64 file and rename it to that file name and reboot.

But I have no idea how this happened - VisualCron is determining the file to install based on the architecture of the server.

The file server_startup.txt looks good (no "pipe busy"):
14.03.2016 11:32:13 Info Credential provider->Credential provider was already installed (C:\Program Files (x86)\VisualCron\InteractiveLogonCPx86.dll)

14.03.2016 11:32:13 Info UAC enabled: False

But runnung the job by right mouse-click and Job start with options the result is:
PerformDesktopUnlock->Desktop Unlock/Logon failed in task: Ausführen, reason: Failed to connect to Credential Provider. Pipe result: 0

Attached the Foreground execution settings:

Hi Henrik,

i read the log_Server-Log file and thinking about the user, who is active in session.

14.03.2016 13:40:03 Debug Interactive logon: EstablishConnection->Wait named pipe failed - try EstablishConnection again

I logon via RDP with the local user "automat" and the job also use this user, can this be the reason for the "busy"-error?

thanks

Did you delete,copy rename and reboot as I described?

The reason while you get Pipe error is cannot communicate with the dll. Most probably because the wrong dll is set now. You need to perform the steps.

Yes, i did these steps.
Now the files look like this:

As you can see the filesize of both x86 and x64 file are the same, because both are the x64 file.

Please test this build:
