We are running VC8 in trial mode (in preparation for migration of VC6 to VC8).
Set proper security policy on server. Server has been rebooted.
Still receiving error "PerformDesktopUnlock->Desktop Unlock/Logon failed in task: Execute, reason: Failed to connect to Credential Provider. Pipe result: 0
Exception in Task: Could not find the specified Connection for Foreground execution." when task runs.
Task is set up for Foreground execution on a specified desktop session, with use any session option on.
Same task setup as the machine running VC6.

I assume this is a new machine?

Please attach server_startup.txt

---

Correct, new machine. Win Server 2012 R2.
Checked that UAC was turned off, rebooted.
Attached. I am getting two server_startups. One in Program Files and the other in Program Files (x86).

Still unable to connect to credential provider after applying 8.0.5 beta

Seems like you got an older build. Please follow these steps:

1. re-download
2. re-install
3. reboot computer

---

Still not working. 8.0.5 right? That is what the log says.
Do I need to FULLY uninstall the first install then re-install the beta 8.0.5 ?

Uninstall should not be needed. This is done everytime you install new version. Reboot is most important. Please send server_startup.txt along with log_serverDATE.txt. Send us the Job name as well so we can see it in action. Make sure you have Extended debug checked in Server settings before Task is scheduled.

---

I did a full uninstall/reinstall but getting same results.

It's only the tasks set to run in the foreground that are the issue.

Will post logs asap

If running task in foreground and session is not locked, might that be the issue? I am thinking the setup is not correct although it's an exact port from V6 and I see busy errors in the serverstartup.

I am not sure. The logs that you sent does not seem complete. Have you really checked "Extended debugging" before running? I am looking for the files:

server_startup.txt
log_serverDATE.txt

Both these should be in x86 folder - other folder not interesting.

---

server_startup_03282016.txt is server_startup.txt

logserver20160328.txt is the logserverDATE.txt file

yes, extended debugging is on

should be the files you are looking for.

server still seems to be getting pipe busy error...

Is reboot taking less than 50 seconds?

52 seconds

Tried starting the VC service delayed.

?

Thanks for the information. We are still doing some more tests and hope to add more debugging soon.

Meanwhile, could you explain your need for Foreground execution - maybe we can work around it?

---

Please test this latest and reboot:

http://www.visualcron.co....aspx?g=posts&t=6564

Foreground execution was a carry over from our VC6 jobs where we needed to see some jobs running for testing purposes.
It does appear when we set to background they work, except they are all (200+) set to foreground currently.
Will try new version posted.

That post points to 8.0.5 which has already been tried (see above).

We do daily builds almost with changes, especially to this behaviour. Please download and re-install.

---

Oh ok. Will do.

The good news is that I am not getting the pipe busy in the server startup log any longer.
Bad news is the job is still failing to connect to the credential provider.

Can you confirm the VisualCron Service (Services MMC) is set to 'Allow Service to interact with desktop' if 'Local System Account' is selected (Log On tab).

I feel like I remember seeing something like this previously when the default install changed that option when upgraded and then was subsequently changed back in future releases. We always use a service account instead of Local System Account so i don't recall what the default is on a fresh 8.0.4/5 install and don't have another system to try that on at the moment.
