Re: [NTSysADM] RE: Unable to obtain IP from DHCP server
Excellent point. Here's an additional thought: If the machine(s) that can't get an address use MSFT DirectAccess, and can't find the NLA internal web site (the site is down, or its SSL cert has expired), then there will be access problems for internal resources, for sure!

[NTSysADM] RE: Unable to obtain IP from DHCP server
And are other client pcs really getting addresses, or is it just that their leases haven’t run out yet? What happens if you release one of the leases from a “working” computer, does it correctly get a new one assigned? Besides looking for another DHCP server, is there ANY chance someone has cross connected two networks (ie subnets/Vlans) together that both get addresses from that same DHCP server? We still have some areas with no spanning tree (not my choice) and it sort of sounds like what we would see if that were to happen. Machines try to get an address but the server thinks they’re connected on the wrong network so doesn’t hand one out. Shows up in the logs as nacks for those systems, and the clue is that you can match the mac address of the requesting system and see it’s trying to hand an address out from the wrong pool. In the same scenario, some machines still get addresses correctly. -Bonnie From: listsad...@lists.myitforum.com [mailto:listsad...@lists.myitforum.com] On Behalf Of Melvin Backus Sent: Friday, March 10, 2017 8:41 AM To: ntsysadm@lists.myitforum.com Subject: [NTSysADM] RE: Unable to obtain IP from DHCP server We still haven’t had an answer to the “what do the logs say” question.
