Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Our old setup (which worked):

On workstation W-1 (WinXP - 64bit) we had two virtual machines (VMWare 6.5) V-1 and V-2 (both with WinXP-32).

All of them had a different IP static address, V-1 and V-2 were bridged to the W-1's NIC. V-1, V-2 and W-1 were/are in a domain with DNS servers S-1 and S-2.

We could open both V-1 and V-2 and see the W-1, S-1, S-2 and all the network (ping, file share etc.).

After a while (in which I was away from this job) I found the following: VMWare upgraded to 7.1, an installation of VirtualBox (dunno if it has something to do with our theme), the settings from V-1, V-2 and W-1 untouched(?) and the following 'weird' situation:

Only the first VM can access the network. IOW, if I start the V-1 I can see (ping, filesharing etc.) W-1, S-1 and the entire LAN. If after this I start V-2 from V-2 I can see only the W-1. Any other ping (including to the S-1) gives an 'Request time out'.

Similarily, if I start first the V-2 and after this the V-1, then the V-2 works ok in LAN while V-1 does not (it sees only its host system).

Any clues how to have simultaneously both virtual machines to work on our LAN?

TIA for any feedback,

John

You might want to check the assigned MAC addresses of both instances to ensure that they are not somehow the same.

Thanks a lot for the answer. However the ipconfig /all shows different physical addresses. –  John Thomas Jul 4 '11 at 6:53
    
You might try deleting the virtual NIC definitions and recreating them? –  user48838 Jul 4 '11 at 7:16
