Latest Patch Tuesday has broken DHCP Server in all Windows Server editions

Microsoft released Patch Tuesday updates for Windows and Windows Server releases roughly a week ago, on June 10. In the latter, the release contained new functions for Narrator scan mode, along with tons of fixes for File Explorer, GDI+, Hyper-V, and more. At that time, Microsoft noted a known issue for Noto fonts, where Chinese, Japanese, and Korean text appears blurry or unclear under certain conditions. Now, it has highlighted another known issue following user reports.

For the past couple of days, users on Reddit have been reporting issues with the DHCP service after applying the latest Patch Tuesday update. Apparently, rebooting the system fixes the issue, which can be understandably annoying.

Now, Microsoft has updated the documentation for the June 10 release notes across Windows Server 2016, 2019, 2022, and 2025, to mention that the DHCP Server service may "intermittently" stop working after installing Patch Tuesday's update, which will impact IP renewal processes on client machines. Redmond has assured customers that it is working on a fix, which will likely be rolled out within the next few days.

Of course, this problem is rather frustrating for IT admins, and that annoyance is reflected in the Reddit thread where customers are blaming Microsoft's software quality assurance practices. The fact that it's currently unclear when a fix will be rolled out may further add to customer grievances.

For those unaware, the DHCP Server service in Windows is responsible for network management such as allocation and configuration of IP addresses in a centralized environment with robust logging and monitoring mechanisms.

And for those keeping track, this is not the only Windows Server issue that has cropped up in recent memory. Last month, Microsoft pushed an out-of-band (OOB) hotfix to patch a Hyper-V bug that was plaguing the platform. Of course, one can argue that problems like these are happening because of incomplete testing, but it is also important to remember that Windows is running on hundreds of millions of devices all over the globe, so comprehensive test case coverage is very difficult, if not impossible.
