Hi,

I have a SBS 2003 with 5 users and everything is working fine until a couple of day’s ago.

Now when a user tries to connect from home to his computer at work with RDP and the sbs2003 vpn connection he gets the following error message: “The RDP protocol component "DATA ENCRYPTION" detected an error in the protocol stream and has disconnected the client.”

Sometimes it appears within one second and sometimes he can be connected for several minutes, it seems like its often triggered by starting a program or changing webpage’s etc.

I have tried to delete the SBS VPN (SBS connection manager) and reinstalled it, same problem. I have also tested out the connection from a different computer and and I got the same problem/error.

When I try RDP connection on the LAN everything is working fine.

I can use the VPN connection for exempel Outlook 2003 with exchange connection, and even surf the “companyweb” without problem, so it seems to affect just the RDP connection through the VPN tunnel.

When I set upp a different VPN connection (Netscreen client) and use RDP everything is working fine again.

I can’t find anything in the eventlogg that guides me in a direction, just the above error messages.

Any suggestions ?

TIA Patrick Klemetz

While I don't believe this is possible,
I had some similar issues.

They resolved shortly after a power failure caused everything (routers, switches, hubs, T1, SBS, etc) to power down.

Again, I don't see how thats possible as the VPN stuff should all be tunneled and not affected by anything but the SBS box (Which we had previously rebooted)  But it's probably worth a try if your users don't mind the stuff being down for a few minutes during the evening.

fruhj is pretty right on... but what happens is an encryption key gets left in the registry if a computer is disconnected via power failure or some other unexpected disconnect.

Please see http://support.microsoft.com/kb/323497 for what needs to be checked.
