Recently I noticed that remote desktop connection stopped working while using vpn.

mstsc dies with "remote desktop connection has stopped working".

On application log I have error:

I'll have session both to default port 3389 and fixed port 9833. I have set to firewall both application mstsc

as allowed and also tcp ports.

Download this file from my Dropbox

https://www.dropbox.com/s/v81q3got2ts52x6/WER_remoteDesktop_full.reg

and import it. It generates dump of the crashing Remote Desktop Connection into the folder C:\localdump. Compress the dump as zip/rar or 7z and uplaod the compressed file to your Skydrive/dropbox and post a link here.

I just went through a similar issue, I wrote about it here.  Your mileage may vary, but check your print drivers.  try not redirecting your printers, or read how I traced the issue.

Although your error seems to deal with the DirectX systems. If you have a dell or brand name computer go to their support site, and updated all your Video, Audio, and BIOS.  You mentioned VPN, what client?  Is it supported on Windows 8.  Almost willing to bet that will resolve your issue

Here's link  skydrive.live.com/redir?resid=DEEA1E465A6F6262!374 for  mstsc dump.

I noticed that i can take rdp sessions to Windows 2003 terminal servers but not to Windows 2008(R2) servers.

Uninstalled all printers and still get this "remote desktop stopped working" when trying to connect to 2008 servers.

add https:// for link, some reason I cannot post link, I got "your account needs to be verified" error.

Trying with Cisco AnyConnect Secure Mobility client and Shrew Soft vpn client.

Both stopped working at same time.

that's what happened with me and my printer... 2k3 was fine but not 2008 or higher 

What model of machine do you have?  As I mentioned the dui70.dll is part of directX,  Chances of if being the vpn clients are meh.  https://skydrive.live.com/redir?resid=F99F34C737E3EFF1!233&authkey=!AD8LaMfiEigUNS0 try posting those minidumps here.    I'll take a look at them.

I can't download the dumps. I always get a skydrive error. upload it to a fast 1 click hoster like RS.com, zippyshare.com or http://rghost.net.

I uploaded those to yours skydrive share that you ceated also..

I can't download from skydrive. There seams to be an issue. upload the dump file somewhere else.

unforunately the dump isn't really helping me, since for some reason the dll list is corrupt and wouldn't let me view your loaded DLLS.

please download http://download.microsoft.com/download/B/B/1/BB139FCB-4AAC-4FE5-A579-30B0BD915706/mpsreports_x64.exe

install it and run it with the Select general info only for now, at the end, save teh results to your desktop and upload to the same shared skydrive link.

Did you guys get anywhere with this or have any info? I'm stuck in the same boat. I tried reading the dmp's and it looks like its all related to system DLL's that handle logins and credentials. I've made it my goal to figure this out and I keep hitting dead ends. There's not even a spot to report a bug I can find.

Any info would be great, thanks.

Further proof it's something with credentials/authentication. I found a valid workaround, but I think this one's on Microsoft to actually fix.

I opened up Remote Desktop Connection, put in my username and clicked the Save Credentials box. Then I edited all the other settings. Saved the RDP connection to my desktop. Then I edited it with notepad, and added the password value. I found a blog that provides a program that'll hash the password for you. I used it so I can say its safe:

http://www.remkoweijnen.nl/blog/2007/10/18/how-rdp-passwords-are-encrypted/

I put the hashed password in, saved the file. Then used it to connect and it worked. So by bypassing RDP having to ask for credentials, it didn't crash when it asks. Kind of inconvenient if you have many computers you have to connect in to. But for those in a bind this will work for you.

upload the dmp, maybe I can see more details.

Maybe you tried to disabe the autologin last user account in windows 8?

"HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVerision\Authentication\LogonUI\UserSwitch  Enabled=1"

I had the same problems when i was messing around with this, when logged on this value should be 0.

In my case, the problem was a file named "bdmpega64.acm", which is an A/V codec that is included with the Bandicam software, as well as many video games. I still haven't determined which software included this codec, or how to remove it without causing problems, but this file is indeed the source of my RD crashing. Disabling sound in the RD connection eliminates the crashing.

Thanks to Andre.Ziegler's debugging work in the related thread: Remote Desktop connection has stopped working" problem in Windows 8, Please help me!

Hi, I got the same problem with Win 8.1. I tried to connect without sharing printers,but it still crashes, here is my log:

I saw a similar crash for Explorer and the Answer from MS is they know about the crash and will fix it after Win8.1 GA. So check for updates in November patchday and hope it is fixed.

Also try the workaround from Stefhan_. This string is also shown in your dump.

This solved the issue for me, thanks for the tip!

Unchecking the option to use my printers in the remote connection fixed the crash for me. I'm on windows 8.1 and was connecting to Windows Server 2008 R2.

This solved the issue for me, great tip!!
