Design Question (multiple same hostname guests on same host)

-

i purchased new powerful server , placed windows hyper-v server (free version) on (we not have system center).

we use prebuilt images student labs (consists of 2 servers work enterprise application).

one guest image has ad loaded own domain on other client server. have automated system copies images , imports , fires them up.

the problem have same hostname , looks duplicate ip addresses on private or internal switch (only external virtual switch receives dhcp, not sure how other internal/private switches obtain ip info). if place 3 students on new server (6 vms total [3 dcs , 3 clients]), first 2 vms appear fine attempting login anyother dc results in error: "the local security authority cannot contacted", can guess getting confused on real dc.

the host has 3 internal switches , 1 external switch internet access.

is there way isolate each student's environment? guessing system center can looking other possible solutions.

thank you, joe

you have behavior because placing duplicates of machines on same network segment.  on boot windows os attempts broadcast name, if machine returns saying 'that's me' shuts down network interface.  have been around forever.  keeps dns clean, ad clean, , guarantees each machine unique on network (and demands too).

to solve place each 'unit of machines' on unique virtual network (in way).

this can done using different external virtual networks on different physical network segments.

this can defined using vlans (essentially same result idea above, 1 external virtual network , vlan segmentation @ physical layer).

the oldest method subnet machines.  manually apply ip addresses in os of each machine , put them on different ip subnets.  environment 1 on 192.168.1.0 subnet, environment 2 on 192.168.2.0, , on.

system center doe snot give solution.  1 additional option of network virtualization.  still have implement 1 of solutions through interface.
