Microsoft has acknowledged that the June 2025 security updates have led to issues with the DHCP service on Windows Server systems. Specifically, this problem hinders the DHCP Server function, which is crucial for managing IP address assignments and configurations across Windows networks.
The issue results in unicast IP address renewals not functioning correctly, with the service potentially becoming unresponsive. Microsoft detailed this in their security advisories published during the month’s Patch Tuesday, citing that this affects client IP renewals.
Impacted versions include:
- Windows Server 2016 – KB5061010
- Windows Server 2019 – KB5060531
- Windows Server 2022 – KB5060526
- Windows Server 2025 – KB5060842
In response to the issues, Microsoft has promised to provide a resolution in the coming days. This acknowledgment follows their effort to address another issue during Patch Tuesday that had rendered parts of Windows Server 2025 inaccessible and had led to authentication problems in domain controllers.
Furthermore, previous updates attempted to resolve issues relating to Hyper-V virtual machines, which experienced unexpected restarts or stalls, as well as problems with launching Windows containers on Windows Server 2019, 2022, and 2025.
Solutions to DHCP errors can often arise from either the configuration of the device receiving the IP address or the settings of the DHCP server itself. Microsoft is actively working to mitigate these issues for affected users.
