DHCP Discover and Request Ignore Option 12 (81:60) After Driver Rollback

Summary

This article provides a workaround for an issue in which Windows 10 ignores DHCP option 12 (81:60) after a driver rollback. This issue can occur when a device has a vendor class identifier (VCI) of MSFT 5.0 (Windows computer) or dhcpcd-5.5.6 (Android device) in the DHCP process.

Workaround

To resolve this issue, manually remove DHCP option 12 (81:60) from the DHCP Discover and Request packets.

Steps:

1. Open an elevated command prompt.
2. Run the following command: ``` netsh interface ipv4 set address [interface name] static [IP address] [subnet mask] [default gateway] ```
3. Run the following command: ``` netsh interface ipv4 add dhcp [interface name] [DHCP server address] ```
4. Run the following command: ``` netsh interface ipv4 show interface [interface name] ```

DHCP option 12 (81:60) should no longer be included in the DHCP Discover and Request packets.
