From File Explorer, choose Computer, right-click and select Properties, then click Change Settings, and go to the Remote tab.įrom Windows 10, uncheck the option to “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)”:įrom Windows 7, it’s setting the option to the Less Secure option rather than More Secure:

Simply adjust the Remote Desktop settings on the host machine to a lower security level. One could rollback the security update, but rather than risking other security problems, there’s a quick fix. There are also reports of problems with Windows 10 machines connecting to Windows 10 machines, and people locked out of their Azure VMs. A Windows 7 PC had no problem connecting to it, but the same user connecting from a Windows 10 machine failed when that was never an issue before and the host machine allowed remote connection for years. The symptoms are rather strange because we found that some machines successfully connected while others didn’t.įor instance, we had a Windows 7 machine that hosted Remote Desktop. However, there are many situations such as development, testing, build, staging, and deployment environments which require a stable environment that would be destroyed by automatic Windows updates. This mismatch between the implementation of a security requirement (which is not optional) without the corresponding automatic update may be the source of this problem. The automatic Windows patch to raise the security level is not implemented if the PC doesn’t allow automatic updates. If your PC received the May update but the target PC hasn’t implemented the CredSSP update, the PC receives the error message when it tries to connect to that PC. It changed the default setting from Vulnerable to Mitigated which means that any PC using CredSSP is not be able to use insecure versions. Security update deployment information: May 08, 2018 The Microsoft Security patch issued on Tuesday, May 8th triggered the problem by setting and requiring remote connections at the highest level (CredSSP Updates for CVE-2018-0886):: It recommends some steps but isn’t very clear what those changes are nor whether those changes are needed to be made by network administrators globally via group policies, or group policies on every PC and VM. It offers extensive information on a series of updates since March 2018. The link goes to this page,, and explains the Credential Security Support Provider protocol (CredSSP). This could be due to CredSSP encryption oracle remediation.įor more information, see https:/go./fwlink/?linkid=866660 Remote Desktop Connection Error An authentication error has occurred. Users received error messages like this when they tried to remote to machines they connected to successfully for a long time: Starting May 9, we received many reports of Remote Desktop connections failing globally.
