Rdp Ignore Certificate Errors
desktop connection - the one in the image: So far I have found that when I check the "don't ask again" checkbox it is generating registry key over here: HKCU:\Software\Microsoft\Terminal Server Client\Servers A new record is generated with the name of the server and key name CertHash that contains a value that is specific for a machine. The key is the same for a machine - if I delete it and check the checkbox the same value remote desktop authentication certificate expired or invalid is again generated. There is a new value in case I recreate the virtual machine so I think it is something machine specific. Can someone tell me how is this hash generated so I can populate the key from command line? Adding certificate is not an option and the machines will be frequently regenerated so I need an option to ignore this automatically as I need to connect a user to the machine and run some programs in it. ssl windows-server-2008 remote-desktop registrykey share|improve this question asked Dec 19 '13 at 16:08 Stoimen 1701417 add a comment| 2 Answers 2 active oldest votes up vote 6 down vote I know this is a old question. But this may help someone who is looking for the same solution. Method 1 You may over ride the certificate check for ALL RDP connections (use it at your own risk) Just add a new registry key as below. reg add "HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client" /v "AuthenticationLevelOverride" /t "REG_DWORD" /d 0 /f Method 2 Considering if you have admin rights on the remote machine, you could actually get the crethash value from the remote machine using the below wmic command. So you could make a small batch file to get this value before you launch the mstsc and add this value in registry. I haven't included the complete batch file but thats the idea. w

From the details in the error prompt, I could understand that the RDP client is trying to validate the remote server's certificate. The RDP client throws error prompt when it could not trust the certificate. The good thing is, the RDP client allows us to bypass the certificate validation and connect to the server any way.The Ideal solution for this is to apply the correct certificate on the server. The Microsoft support article https://support.microsoft.com/en-us/kb/2000960 explains how to verify the selected certificate on the server.In my case, I don't have the control over the servers. But I'm sure the servers I connect, are trust worthy. So, It is annoying to see this error message every time when I connect to the servers. And, every time I have to select the check box "Don't ask me again for connecting this computer".On searching the web, I came across an article on bypa

I marked the "Don't ask me remote desktop certificate again for connections to this computer" box, and then accidentally clicked No (do not connect) instead of Yes. Now when I try to connect it asks me for my password, but then it does not connect and it goes back to the RDC login prompt. How can I undo this setting? I looked in the MMC Certificates snap-ins, but did not find anything that looks related to my work computer. I also tried deleting Default.rdp, but there's nothing relevant in that file either. Any help is much appreciated! remote-desktop certificate share|improve this question asked Jun 15 '11 at 14:26 pibboater 80126 In the connection dialog if you click Options, then click the Advanced tab you can choose what to do if the server cannot be verified. Make sure it's not set to 'Do Not Connect'. –James P Jun 15 '11 at 14:47 1 James, thanks for replying. I've tried each of the options there, and even "Connect and don't warn me" results in the same behavior, so I think my mistake with the "Don't ask me again" setting is overriding this. –pibboater Jun 1
problem for a client who was connecting to our Remote Desktop Servers. This was a very large client with elaborate IT policies in restrictions in place. Due to port restrictions in place they were unable to connect to our public RDS bank as their network did not allow port 3389 (RDP port). So we installed a publicly accessible Remote Desktop Gateway server and had them connect to it over https (port 443). We also had them upgrade to the latest version of RD Client - Remote Desktop Connection 7.0 for good measure. Pretty soon the "unexpected server authentication certificate" error message showed up on all the computers. A quick internet search revealed a failed CRL (Certificate Revocation List) check to be a common cause of this error. Configuring RDP Server authentication settings to "Connect and do not warn on errors" did not fix the problem. The only choice was to find a way to fix the problem. Like other secure environments I have encountered, the client's network was blocking all egress traffic from within the network. For http & https the Internet Explorer was configured to use a proxy server. (Apparently outbound traffic through the proxy server was allowed.) We looked up the CRL update url from the certificate. We were able to browse to the url with Internet Explorer and download the revocation list without any trouble. Yet somehow the RDP client was not able to connect to the URL. Several days passed by before it hit me out-of-the-blue. The RDP client was obviously using WinHttp and WinIE to connect to the URL. WinHttp on a default windows installation is not configured to use the proxy. An internet search helped me find Windows Server 2008 Replacement of ProxyCfg.exe. The article specifies the comma
