I just setup a Windows 2016 Standard Server running DHCP for our network of two VLANS native 10.6.1.x /24 and other 10.6.2.x/24 The DHCP server sets on the native VLAN and works perfect for all clients. I have set DHCP relay on the 10.6.2.x VLAN and pointed it to the DHCP server on the native VLAN. The issue I am having is very slow IP assignment to (up to five minutes or not at all on the Chromebooks) Mac OS clients, iOS clients, and ChromeOS clients. I did a packet capture and saw the request for an IP address. Five minutes later it finally assigned an address, but it was different than the first one that was offered.This does not happen for Windows Clients. I tested one this morning and it had a fresh new IP even before I signed onto the computer. Any ideas? My network is very small so I could go back the way I had it and have the MX do the DHCP. I went through yesterday's DHCP server log and found it had issued 1790 NACK during a 24 hour period. All of these NACK relate to the 10.6.2.x/24 which is the VLAN having DHCP relayed by the MX 84. Thanks for reading.
