I have a client that has 50-60 workstations and a handful of servers. Recently the DHCP pool exhausted IP's and it was discovered that multiple IP's were being used by RAS connections on servers and workstations. To verify this, I'm able to delete the "Incoming Connections" adaptor on a workstation and the associated DHCP leases disappear on the server. The next day, the "Incoming Connections" adaptor is back, and of course using IP leases. I've looked through all GPO's and don't see anything that would do this, maybe I'm just missing it. Is there anywhere else I should be looking to make sure the adaptors go away and stay away?
Thanks for any tips.
