Investigating

Technology Solutions & Services identified a flawed Microsoft patch impacting Windows machines connected to the wired network (not WiFi). This flawed patch disrupts wired network connectivity and causes unnecessary login prompts that fail. To mitigate the issue, TS&S has reversed this patch, and as a result, affected machines are being forced to reboot.
