Remote Desktop Connection problem with multiple Lenovo machines

2012-07-11, 16:55 PM

Hello,

 

I've been running into issues with connecting to some of the latest Lenovos we purchased using RDP. It has happened with a batch of 3 x220s and a batch of 2 Thinkstation C20s (possibly others that I haven't yet had to remote into).

 

The symptoms are maddening in the paucity of information given for the failure. It basically goes like this -- type in the name of the computer and hit connect. Immediately I get a "this computer can't connect to the remote computer"; it's so sudden that it seems to be getting rejected immediately. I've check every windows log (even the ones under Applications and Services) and the ONLY thing logged (on the destination computer) is that an RDP session was initiated. NO reason is given for the failure. No error event given.

 

Has anyone else run into this? I'm having to use 3rd party software to log in to computers, which is becomming a nuisance as I am trying to set up computers at a branch office for new users. Is there some way to debug RDP? I ran a packet sniffer and a total of 6 packets are passed for these "sessions" -- mostly TCP handshake packets at that, and only one actual RDP packet. Is there a more verbose log I should be looking at?

 

Any help would be greatly appreciated!

Are you using the Lenovo preload, or your own installation of Windows?

Thanks for the reply--

 

I'm using the Lenovo preload. I used the Lenovo system update to make sure all software and drivers are updated (as well as Windows Update, of course).

Can you ping the systems?  I tried this on a preload and found that I was able to connect by Remote Desktop once I disabled firewall components that were blocking ping...

Yes -- as a matter of fact, I have a setting in group policy that turns off the firewall when the network profile detects it is on the domain. I checked just to make sure, and they respond to pings.

I don't mean to insult you, but have you checked to make sure the client systems have one of the bottom 2 options checked?

 

 

If so, then I don't have any other ideas about why RDT isn't working for you.  You might need to ask Microsoft if they have any other troubleshooting techniques.  Sorry I'm out of ideas about this one.

If you can't connect to your new or restored Lenovo with the OEM install of Windows 7, it may very well be that the particular registry key below is not set to the typical default value (I think Lenovo has messed up their OEM install image). The two secrity packages 'tspkg' and 'pku2u' are missing on OEM Lenovo images.


This registry key:
HKLM\system\currentcontrolset\control\lsa\security packages

Should look like this:
kerberos msv1_0 schannel wdigest tspkg pku2u

Fix it and RDC will connect.

(may need a reboot to take effect)

warmbowski --

 

Thanks, that was what ended up fixing the problem on the computer (and a few others) in question.

Hi Warmbowski


Could you instruct me on how to fix the issue. Where can i download the packages 'tspkg' and 'pku2u' and how can i integrate them with my existing win 7 version given by Lenovo.


Thanks
