I've been running on the same windows 7 64 bit build on a Dell M4500 for well over a year in RDP sessions daily over VPN's without issue. Suddenly one day last week i began receiving this error. I can, onoccasion, connect to local LAN RDP's without change security layer of the rdp-tcp session to "rdp security layer" the error immediately but have experienced the error even on LAN sessions after 3-5 minutes of use. Sometimes on a LAN it will go much longer. Now, for remote sessions, i cannot authenticate at all. I typically get to the login screen, enter my credentials, then immediately the error pops up and drops the connection. Every time. I've tried this to multiple different WAN's so i know it's not at the server level. I also know it's not on my LAN as other PCs on the LAN connect fine without this error so it's local to this PC. After hours of diagnosing and reading articles i decided to just rebuild from the ground up, fresh install of windows, applied all service packs, updates and installed my VPN client and attempted the connection -- same error. I even used a brand new HDD (SSD) as i was wanting to upgrade it anyway. Now i recognize that i should have tried the connection before all other patches were installed (troubleshooting 101, sorry) but trying to avoid a 3rd install and hoping for assistance. I typ

joe0 ⋅ 4 Comments Following is a solution for RDP error: Because of a protocol error detected at the client code 0x1104 this session will be disconnected. Two ways to fix the issue: 1. In your RDP client settings, remove all checkmarks from Experience tab (see http://www.joe0.com/2013/08/23/solution-for-rdp-error-because-of-a-protocol-error-detected-at-the-client-code-0x1104-this-session-will-be-disconnected/ screenshot below). This seems to work for most people: 2. If you're running your RDP server on a non-standard port (such as port 443-https), then it's possible some other app is fighting over the very same port. In that case, you'll http://serverfault.com/questions/510450/issue-connecting-over-rdp-when-on-windows-vpn need to find out what else may be using the port assigned to RDP (i.e. 443 in my example) on your server. To do so, following steps will help you determine this: - Open a command prompt window. From Start / Run protocol error enter: cmd - From the command prompt enter: netstat -ano 1 netstat -ano - Look for PID which indicates usage of the port 443: - Mark down PID, then download Tcpview and run tcpview.exe. Search for PID you've found by using command line netstat call. You'll find what app is taking over your RDP port. In my case, I could see that Skype is trying to run its service on port 443: - Solution in this case would be to completely close out of because of a Skype. Or simply Kill/Uninstall or temporarily disable the Skype. While in tcpview, you may as well do so: Let me know if this helped.

On my Windows 7 box, I have a VPN set up in Windows. Today I was on the VPN and logged into an RDP session with no problem. I disconnected from the RDP session and the VPN. A few minutes later, I got back on the VPN, and when attempting several times to connect to the server over RDP again, I got several error messages: Because of a protocol error this session will be disconnected Because of a protocol error detected at the client (code 0x1104) Because of a protocol error detected at the client this session will be disconnected When attempting to browse a website in Chrome while connected to the VPN, no stylesheets would load. Google Drive lost connectivity, though Dropbox did not. Firefox displayed the following message: The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. I am also seeing SSL Protocol errors in Firefox, and other errors when secure (port 443) requests are made. Disconnecting from the VPN made browsing normally possible again and Google Drive came back. I have another Windows VPN which I connected to - same issues. The only thing I can think of is I earlier added a Windows Firewall rule to open ports 53, 88, 138,137,139, 389, 445, 636. I deleted the rule, rebooted, and even turned off the firewall and disabled Microsoft Security Essentials but the issue did not go away. One other thing - for servers where I do not have to be on a VPN, I can remote desktop fine. I'm at a loss. Any ideas? windows-7 rdp vpn share|improve this question edited May 24 '13 at 11:03 asked May 24 '13 at 1:58 clickatwill 1063 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote In my opinion it is the VPN client (which one are you running?)
