Hey guys, I have been having some trouble with my laptop for work. We use the “Remote Desktop Connection” through Windows at our office to connect to our server and I keep getting disconnected and the error says “Because of an error in data encryption, this session will end. Please try reconnecting” I does it every couple minutes it seems like. Could this be from a virus or something? The spybot search and destroy program didn’t find anything and neither does the Trend Micro virus software that my computer runs. Any ideas on what the problem could be?
I’m guessing that your IT department configured whatever server your connecting to to require encryption. I believe that you’ll need to set an IPSec policy on your machine to use encryption when requested…
Try this:
Start>Run>mmc
Add Remove Snap-Ins add IPSec Policy Management, select Local Computer
Right click on “Client, Respond Only” and select “Assign”.
Try connecting to your server again…
that or they are forcing SSL and using an internal cert?
sounds like you need to contact the windows admins.
So did I fix this or what?
Well???
maybe he complained at work and they blocked him surfing the interweb to pittspeeed??? 
i’ve done something similar in the past 
LOL! I’ve done similar as well.
You guys like the BOFH style of administration I see.
I’m guessing something similar, like the session key or an encryption key rotates and one of the computers never gets or acknowledges it causing a mismatch.
Don’t use FIPS at all because RDP doesn’t play nicely with FIPS from what I heard.

Who said anything about administration? 
Besides, I’ve never restricted a users access based on spite… in a few cases users questions to our support staff alerted me to ways that users were bypassing our security implementations which I then fixed (for example, a user wanted to know why she was having issues accessing her free mail account while connecting via an external SSL proxy).
it is a pain when you have compunding factors like constrained bandwidth… we just use m$'s implementation of ipsec between machines… networking guys hate it because it encapsulates the traffic but oh well
