Microsoft breaks DHCP with latest Windows 10 update; suggests a reboot to get back online

Microsoft have issued a Windows 10 Update which appears to break the DHCP service, rendering it useless for some customers.

DHCP is a network protocol that allows network devices to send a broadcast to DHCP servers. If a server is present (such as a router), it responds with IP address information that the computer uses to access the network.

If the service is broken or behaving unexpectedly, customers are unable to access the internet or local network resources, which appears to be the behavior that some Windows 10 customers are experiencing after the update.

A spokesperson for Microsoft said they are aware of the issue and gave the following advice;

“Some customers using Windows 10 have reported difficulties connecting to the internet, as a first step, we recommend customers restart their PCs.”

“If this does not resolve the problem, visit our website for further support.”

A number of European ISP’s have highlighted the issue, with Virgin Media creating a dedicated community support page with their own instructions for resolving the issue.

Advice from both Microsoft and Virgin Media seems to suggest that a restart (not shut down) might resolve the issue. However Virgin Media do go a step further, with instructions that include how to release and renew your IP address and flush your local DNS cache.

At the time of writing, Microsoft hasn’t responded to our request for more information about which update is impacting the DHCP service. Various forums online have so far been unable to pinpoint the problematic update, making potential removal of the problematic software more difficult.

Enterprise customers who have the option of using the long term servicing branch (LTSB) will not be affected by the issue, as updates are purposefully delayed in case of eventualities such as this.
