Remote Desktop Data Encryption Error

[Joe]

I keep getting "Because of an error in data encryption,
this session will end. Please try connecting to remote
computer again". This only happens when I connect to one
particular computer. I have three computer that I remote
desktop on but only one gives me this error.

I'm getting the exact same error...it's very frustrating!
Any help would be greatly appreciated...why is this
happening?

I am getting the same encryption error while connecting to a Microsoft
2003 server from a Windows 2000 Pro client using the latest Remote
Desktop client that was released in May '03. Any ideas or suggestions
for this issue would be appreciated.

This error isn't easy to diagnose - the main cause is network
corruption/transmission problems, but an update (sevice
pack/hotfix/etc) that wasn't installed properly can do the same thing.

.I am getting the SAME error; on my LAN, I have no

problem connecting to the server, but via the internet, I
get the error. On my LINKSYS router, I have port 3389
opened under FORWARDING, but this didn't correct the
error.

Someone said that this is a Linksys Router problem, but I
am doubting this, as the problem occurs with other users
without this router.

Any suggestions would be appreciated.

There are a few issues with Linksys Routers with recent firmware and
Remote Desktop. Take a look at the Linksys forum at
http://www.dslreports.com for more information.

I am having this same problem and I am using a Linksys
Router. Now that I think about it, I've just upgraded
the firmware too. Anyone have any input? I am on my way
now to check the Linksys Website. I'll post back if I
find anything out.

Thanks!

I believe the article:

http://support.microsoft.com/?kbid=323497

has helped to correct the problem.

Hi folks, have has a bit of same issue, in short, found that with my nvidia setup on machine, i let it install its network manager which interfered with microsoft encruption scheme (even though I didn't "use it"), when i uninstalled nvidia's network access manager, problem dissappereaer. No offense to nvidia or others but like all 3rd party venders, if they offer something that does what is already built into windows, then better off not installing it, windows likes only taling to istef in its own language..

Solution!!

I know this is an old thread but the problem still exists.

Ok, been running Windows Server 2008 for about a year. Windows Update stopped working about a 2 weeks after setting up the server. Also, RDP was always spotty. Disconnect instantly on connect or sometimes would give you a minute or two. But was alway that encryption error.

Anyway go to NIC properties and DISABLE "offload TCP Largesend" Once I did this, I lost remote desktop for a few minutes then it came back automatically. Haven't lost the connection sense and it has been about an hour. I decided to try my update again and it is working!!!! That one change fixed both remote desktop and windows updates!

I couldn't find answers to either of these problems anywhere but this works.

Thank you jcjenk

You solved my problem. I'm using Windows 7 and when i use the remote desktop connection i have that problem of after 2 seconds lost connection with remote computer.

I follow your instruction and give the value: off to the Task Offload in the Advanced Settings of my network controller.

I don't know if this error is something related on new drivers that windows update install or something else, but now the Remote Desktop is working well.

Many thanks.
