Windows 2008 Termdd Error 56


AV on the users work PC is centrally managed so it is the same as others it can connect to :(   Tried: Updated the work computer NIC. Tuesday, May 10, 2011 2:45 PM Reply | Quote 0 Sign in to vote Hi All, I got this issue when connecting from a Vista laptop to a 2008 server via Have you performed a reverse lookup on them to ensure they match hosts on your network that you know and trust and are a part of your company's trusted assets? After changing "Security Layer" to "RDP Security Layer" problem resolved. have a peek here

With HP servers often a new PSP Pack might be the issue. I've been able to verify that the IP's in question shouldn't be connecting to this server, but I can't find anything else related to those IP's in the RDS & Terminal You can also check the RDS/terminal server settings and see if there is a timeout set on sessions; there usually is a default one, so I'd look for that first. Sympthoms : - RDP Session may freeze. - Black screen inside RDP window. - Slow connection. - You may also be disconnected. https://social.technet.microsoft.com/Forums/windowsserver/en-US/981a30b8-0e46-49f9-a13f-095b124328fd/event-id-56-termdd?forum=winserverTS

The Terminal Server Security Layer Detected An Error In The Protocol Stream Server 2008 R2

http://msdn.microsoft.com/en-us/library/ms793164.aspx For the protocol details, message syntax and code references you can review: [MS-RDPBCGR]: Remote Desktop Protocol: Basic Connectivity and Graphics Remoting Specification http://msdn.microsoft.com/en-us/library/cc240445(PROT.10).aspx or in PDF format: http://download.microsoft.com/download/9/5/E/95EF66AF-9026-4BB0-A41D-A4F81802D92C/%5BMS-RDPBCGR%5D.pdf THANK YOU! You do get an error along the lines of 'security layer' For example, server-side has NLA-only connections allowed, XP client with RDP6 (is RDP7 available for XP?) supports NLA but you NIC speed setting was set to the lowest available anyway changing it didn't help :( The user does have a parental control firewall thing at home which at the time i was unable to disable

Aug 08, 2012 The Terminal Server security layer detected an error in the protocol stream and has disconnected the client. I had the "LSA could not be contacted" error message, and it turned out to be because I'd set a restriction on which computers an account could log on to.

What Is Termdd

To track this down, I looked at the binary data attached to the event. https://community.spiceworks.com/topic/335964-very-unique-rdp-issue-possibly-relating-to-event-56-source-termdd It seems strange to me that there are no other records of these IP's anywhere in Network, TS\RDP or Security Logs. –epicTurkey Feb 22 at 20:40 1 So, I get The Terminal Server Security Layer Detected An Error In The Protocol Stream Server 2008 R2 On the target computer there were these event logs: Name: System Source: TermDD Date: *theSame* Event ID: 56 Level: Error User: N/A Computer: * Description: The Terminal Server security layer detected Event Id 56 Application Popup Just in case I also did: netsh int tcp set global chimney=disabled netsh int tcp set global rss=disabled netsh int tcp set global autotuninglevel=disabled And guess what.

The clients are running the latest version and the server is already set to use any version of the remote client. http://pubdimensions.com/event-id/windows-2008-error-1530.php have to reg-hack to enable NLA connectivity support on older OS's.
