Hi everyone,
I stumbled across some interesting behavior of the DHCP Service in Windows Server 2008 R2. I have a single, physical Server, which is connected to two different LAN segments. For each LAN segment, I have a corresponding scope configured. If a client is connected to one of the LAN segments, it receives an IP address as usual.
BUT:
- If a client has a reservation configured in the first LAN segment but connects to the second LAN Segment, it is still assigned the reserved IP from the first LAN Segment.
- If a client move from one LAN segment to the other, it still receives an IP address out of the previous scope - until the lease time of the assignment runs out.
There is no shared link between both LAN segments. Each LAN segment is a separate VLAN. No bridges. Not even routing between the two.
So roaming between the LAN segments seems to be a problem. Any ideas, how to fix this?
