t510 Disconnecting RDP Sessions

Hello,

 

Just deployed our first t510 and I have to say I was massively impressed at how easy it was!!!  We are using it to RDP to a Windows 7 VM and I was told by staff that it just disconnects during the day.  Realizing this could be any number of issues, I wanted to see if what logs or events or anything I can obtain from the t510 that would help me diagnose the issues.

 

Thanks!

Re: t510 Disconnecting RDP Sessions

Just off the top of my head:

 

When we were having issues with disconnects, it turned out to be conflicting IP addresses. Make sure that you're using DHCP and that there's plenty of addresses in your scope.

 

Maybe not the issue, but it certainly was for us.

Re: t510 Disconnecting RDP Sessions

Hi,
Are they disconnecting during idle time? or are they disconnecting during active use?

Re: t510 Disconnecting RDP Sessions

Is the disconnection happening without an error message?
Maybe also the Server Log might give a clue.

Re: t510 Disconnecting RDP Sessions

Thanks!  I suppose there could be a conflict, although my DHCP logs would have told me but then again, I've seen stranger things happen...I'll check though and make sure...

Re: t510 Disconnecting RDP Sessions

Hi,

Can you advise what operating system you are using?

 

The T510 can use WES2009, WES7, Thinpro or Smart Client.

 

For different operating systems, I may be able to suggest differnt things.

Re: t510 Disconnecting RDP Sessions

We had the same problem.  Contacted HP support which gave these instructions which worked great:

 

1. On the thin client get into the Administrator mode and then open the xterminal.

2. Type regeditor and hit enter.

3. That will open the Thinpro Registry Editor.

4. Under Registry tab, select "Connection type", and under connection type select "freerdp", and under freerdp select "connections", and under connections, expand the UUID which will besimilar to {9d84f354-4e7b-4564-88a8- 9635473c20b7}, and under that highlight "timeoutwarning". On the right side, you will see the key Description.

The value will be set to 4000 by default. Change the value of timeoutwarning from 4000 to 0. Save and quit.

Re: t510 Disconnecting RDP Sessions

Hi, 

 

I have exactly the same problem as described above,  

 

When i change the timeoutwarning to 0 it does not help. 

 

So i tried to change the timeouterror setting to 0 but that is not allowed by the system.  

 

Any idea on how to solve this ?

Re: t510 Disconnecting RDP Sessions

ThinPro and Smart Zero implement a timer feature that tests if the server is still reachable from the thin client.

 

The client will test and report if is has not been able to contact the server for the nominated period.

 

MSTSC does not implement this feature so will not give similar error.

 

If you are seeing this error, you have network issues between the thin client and the RDS server. Users will be impacted by these network issues and the ThinPro FreeRDP client is trying to warn you.

 

If you have bumped the counters out to a larger value and still see errors, you really have network issues.

Re: t510 Disconnecting RDP Sessions

Josim,

This probably should be a new thread.

 

What you want is not really available - BUT there are better ways.

 

The T510 can run at least 3 operating systems. Please clarify what operating system and version you have.

Re: t510 Disconnecting RDP Sessions

I'm having the same issue. We have a mix of Wyse terminals and HP t510/5655 terminals, and this issue affects ONLY the HP thin clients. I have adjusted the switch ports for HP clients to be 100MB/Half Duplex, I have changed the value for TimeoutWarning to 0, and I have replaced patch cables. I have tested the cables from the wall jack to the switch, and there are no issues. They are relatively new HP Procurve J8773A switches with a single gigabit trunk between them (2 switches.)
We don't have STP running, so if there were some kind of loop, we'd know because the network would die.

These thin clients are running ThinPro t6x44017

 

Basically, they will randomly freeze and disconnect their sessions (while all wyse terminals stay connected and get no disruption in speed or performance.) I have them reboot their HP boxes and they are able to get back in. Up until the disconnect, the performance seems to be fine on the HP clients.

How can I help further diagnose or investigate this issue? I'd love to help because this is ridiculous. The following is a user's description of the symptoms:

(Terminal Server) is running extremely slow and choppy. I am currently in GMail and
the words are showing up after I've typed out the entire sentence; I'm
using Chrome to access Gmail. In (Cloud CRM), it's running slow as well and that is

in IE. I click on one thing and it takes 15 -20 seconds to respond. This
is happening in all applications. Chrome (any website), IE (Cloud Systems, Web Pages),
Adobe Reader and the Desktop version of (Document Management System.) My mouse is moving very
choppy and all over the screen. It did this earlier today (sometime after
4 pm). Eventually, I was kicked out of (Terminal Server.) I logged back in and all of
my applications were up and running fine. This just happend again. While
I was typing this e-mail, I was kicked out and it box popped up stating it
was trying to connect to the server. After about 3 minutes, I was able to
log in. Again, all applications are still up and running fine at this
point.

Re: t510 Disconnecting RDP Sessions

For what it is worth to you we are having exactly the same issue in an environment very similar to yours using a mix of t510/ t5565 and PCs and having done the same checks and changes in our network.

 

Changing the TimeOutWarning from 4000 to 0 did lower the frequency of occurance.

It did not solve the problem though.

 

The Terminal Server session is never affected, so the issue must lie inside the HP Client.

Suggestions HP ?

Re: t510 Disconnecting RDP Sessions

Hi EickSliver and rlovlien,

 

I can only encourage you to log your issues with HP. You have 3 year support (at least in my country) with your devices and that covers issues like this also.

 

I could try and replicate you issues in my lab, but I cannot, and I have tried.

 

For users I have dealt with that were seeing the issues, they were getting message only and they dissapeard when the timer was increased.

 

These issues are a real pain to troubleshoot via forums, and still very hard anywhere remote, but logging a case is the first step.

 

Regards

Andrew S.

Re: t510 Disconnecting RDP Sessions

Your issue may be the same as mine. I found it was a GPO that caused the problem to occur. It seems FreeRDPv1.1 does not update the connection status as the previous version did.

 

GPO: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connection\Configure keep-alive connection interval

Re: t510 Disconnecting RDP Sessions

I got it thanks any way. My client uses vpn to access out TS servers using  the thin clients so I basically found a way to flash the OS of the thin clients which is much easier

If you use versionT6X41019 the issue gows away.

Hi,

 

Try ftp://ftp.hp.com/pub/tcdebian/updates/4.4/service_packs/

 

This is the back door. Normally the full kits are avaiable via hp.com/support then click Downloads and Drivers, enter your product and follow the links down.

Re: t510 Disconnecting RDP Sessions

Hello,

 

I am having the same problemens with my thinpro t510's:

-laggy & hanging rdp sessions

-disconnecting rdp sessions

 

but can differ some more:

HP T510 ThinPro T6X51007 : RDP Server 2012R2 in LAN = OK

HP T510 ThinPro T6X51007 : RDP Server 2008R2 in WAN via VPN = FAIL

HP T510 WIn 7 Embedded: RDP Server 2012R2 in LAN = OK

HP T510 WIn 7 Embedded: RDP Server 2008R2 in WAN via VPN = OK

 

 

As you can see Win7e does NOT have the problems the Thinpro version has, so it's definately not a network issue.

RDP session from Windows 7/8 Notebook to any of these servers is OK also.

 

I tried the following:

1) installed the latest t510 bios V1.05

2) freerdp update to 1.1.0 hp4 is not applicable, since T6X51007 has a new version already 1.1.0-hp6.17

3) chaning timeoutwarning to 0 does not help

4) changing GPO: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connection\Configure keep-alive connection interval to 999.999

5) installed hotfix KB2647409 as per http://support2.microsoft.com/kb/2647409

 

why is this problem still not solved??

Re: t510 Disconnecting RDP Sessions

Hi,

So "T6X51007" = V5.1, which is a very new version of HP ThinPo. I do suggest raising a case to HP so you can be advised if this is a known issue with the new version. There may be a quick fix. If it is an issue with the new V5.1, HP need to know.

 

I would suggest maybe trying to install V5.0 which will be available from the HP web site, Support, Drivers and downloads etc.
