WINDOWS SERVER 2012 REMOTE DESKTOP NOT WORKING UPDATE 2018 INSTALL
On 8th May 2018, an update was made to correct how CredSSP validated requests during the authentication process.įurther, Microsoft found a CredSSP error during RDP and found a fix for the vulnerability by mandatorily requiring both the client and server computers to install the patch. Hence, the patch changed how authentication was done with CredSSP and created “stricter” rules for server-client communication.

As a result, the 2018 CredSSP error affected all applications depending on CredSPP for authentication.Īdditionally, CredSSP was susceptible to the “man in the middle” attack if the user ran a Remote Desktop Protocol session. Set the If server authentication fails to Connect and don’t warn me. Try to disable the Server Authentication warning in the Advanced tab of the RDC client.

Press the Install button to confirm your selection. Open the properties of your RDP connection in Remote Desktop Connection windows and make sure the ‘ Reconnect if the connection is dropped ‘ option is enabled on the Experience tab. Select the check box next to Wireless LAN Service. To enable support for wireless networking: Open Server Manager. Unfortunately, a remote code execution vulnerability existed in the protocol!įurther, if an attacker were to exploit this loophole, they could access user credentials and execute malicious code on the target machine. But in my case, I run Windows Server 2008 R2 on my laptop (HP Elitebook 8540w), so. Further, it uses TLS (Transport Layer Security) to make the transfer safe. Moreover, it does this by securely transporting user credentials from a client computer to a Windows server via an encrypted pipe. What is Credential Security Support Provider Protocol?įirstly, CredSSP protocol is an authentication provider that takes on “outsourced” authentication requests from third-party applications and processes them.

Therefore, to know how to fix the CredSSP error during Remote Desktop or RDP in Windows, read on! However, you can “reinstate” this communication by rolling back the update, as we will show you below. Moreover, clients with this patch could not communicate with unpatched servers. They made it compulsory for both client and server computers to install the update for streamlined functioning. Many servers had to be rebooted as people thought it was a server-side error!įortunately, Microsoft was aggressive in their stance to tighten the security of applications. Unfortunately, this code patch created some ripples, which lead to authentication errors in the Remote Desktop Protocol (RDP) of a Windows server.įurther, a CredSSP error resulted in Windows servers becoming inaccessible via RDP for many users. In the screen wich will pop-up, you will find that checkbox. To find this settings on the Windows 2012 R2 : right click on 'My Computer', choose 'Properties' then 'Remote Settings'. On 8th May 2018, Microsoft launched a patch to fix gaping vulnerabilities exposed in the CredSSP module. I solved the problem by unchecking this box on the server: 'Allow connections only for computers running Remote Desktop with Network Level Authentication (recomended)'.
