Security Updates blocking remote user access on Windows 10 Server

[legolasdory88]

We run a Windows 10-based server with 6-8 users. For about a year, periodic updates that include a "Security Update" disable the ability for multiple users to access the server simultaneously. Our employees need to log into a Visual Basic-based program, typically with 4-6 users accessing it at the same time. When the security update is installed only one user can access the program at a time, and any additional login disconnects the previous user. Uninstalling the security update restores remote access for multiple users. How can we fix this issue so that security updates don't disrupt remote user access?
