Solved: PCOIP Session Disconnects after 15 minutes

Andrew_Keller_C · ‎08-22-2012

http://communities.vmware.com/docs/DOC-17799

I have about 50 clients that all disconnect from their PCOIP session after 15 minutes. It will disconnect regardless if they are actively using the mouse/keyboard or not. In windows Application log, I receive a VMware View Event 102 stating

"Pending portal logon timed out for user DOMAIN\User, wssm may have failed to start correctly, or the user was not able to connect and log in. Pending count left=0"

I have checked the following VMware DOC (http://communities.vmware.com/docs/DOC-17799) and the Userinit registry key is correctly set. I also verified that the WSSM process is started. So the key is functioning correctly as well.

If I restart the WSSM.EXE process, the problem is delayed for a few hours, but then comes back and disconnects users after 15 minutes again. Having to restart this process on each of these VMs is getting to be a pain.

I have tried changing the Connection Ticket Timeout setting in the GPO ADM template, but the max setting is 900 seconds (15 minutes). I know that I can change the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\Agent\Configuration\VdmConnectionTicketTimeout" directly, but I don’t want to work around the problem - I would like to fix it.

From my understanding, the user gets a valid ticket upon connection, 15 minutes later the ticket expires and the user is disconnected, then the user immediately reconnects and the cycle repeats. I assume the ticket it supposed to get a new ticket sometime in that 15 minute window, but for some reason is not.

Any ideas?

take a look at your PCOIP logs and see if you can determine what the disconnect code is. You can cross reference here to see why it's disconnecting.

R U certain that the key: HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon

has the "Userinit" with the data of: C:\Windows\system32\userinit.exe,"C:\Program Files\VMware\VMware View\Agent\bin\wssm.exe",

?

I'm sure u check it a million times already.

Yep. Double checked the key again, it is exactly as you posted.

Wouldn't the wssm.exe process not be running if that key was incorrect?

LarryBlanco2 · ‎08-22-2012

It could be running if it's being called from somewhere else. I saw in that DOC file posted about that they have it being called from:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

By chance, it's not being called from there is it?

No, It is not referenced in the Run key.

And u are using SSO to log in to the desktops.

Andrew_Keller_C · ‎08-22-2012

I believe so. That is where the user types their username/password into the zero client and it "fowards" it on to Windows so they dont have to login in again, correct?

If that is correct, then yes - we are using SSO.

LarryBlanco2 · ‎08-22-2012

Can u look at the log files located @:

C:\ProgramData\VMware\VDM\logs

They will be named: log-2012-08-xx.txt

Look for any info regarding the disconnects and post.

Thanks,

By any chance, r u'r clients logging in through the secure gateway (Usally Externally) or are they using the connection server?

"Use PCoIP Secure Gateway for PCoIP connections to desktop" and "Use secure tunnel connection to desktop" are both unchecked.

take a look at your PCOIP logs and see if you can determine what the disconnect code is. You can cross reference here to see why it's disconnecting.

In the pcoip_server_ log I am getting the following error:

SERVER: map_agent_to_tera: DISCONNECT_GENERIC -> TERA_DISCONNECT_CAUSE_HOST_BROKER_GENERIC

which quates to:

"PCoIP connection not established because of cancellation. This should not occur. Contact Teradici support."

So, I guess I know where I am going next.

Thanks for your help everyone!
