BESR restored virtual images, trying to get them to talk on internal ip range 10.0.0.0

I have used Symantec BESR to create images of my company's servers which i have then converted to Vmware server compatible virtual images. The idea being to create a cheap disaster recovery solution.

The "real" servers currently have static IP addresses in the 10.0.0.0 range and run a DHCP and DNS server on this range as well as running Active Directory, Exchange 2003 & SQL server.

I need to get each server to be able to ping each other and also i'd like to be able to add machines to the domain as well and access the internet (in essence replicating all functions of the existing servers)

When i try to reconfigure the Vmware networking interface and add the 10.0.0.0 range into the DHCP it doesn't seem to work. It either throws up an error stating error code 0 or accepts the change but the servers can't ping.

My PC which is running the Vmware server is currently running an IP range of 172.168.0.x which is used for local networking as well as the internet.

Is the above possible using Vmware Server (free) 1.07 ?

Any assistance greately appreciated

Be carefull when doing something like this, if you have DNS resolution between the two different networks you can cause IP/DNS conflicts.  If you want to replicate a production environment you can use host only mode on the vmware but that leaves you without an internet connection.  What I have done in the past is either you anohter inteface off of the firewall/router or install a small cable/dsl router and use the NAT feature to isolate the test network.  I have setup NAT on VMWare Server but would rather not use it in case DNS and resolution isssue may occur.  Since you're using BESR (BTW 8.5 just came out) you can copy off to USB drive from your prodution network and connect to VMWare Server on your test network.

Thanks, i was going to, once getting host only working, using another ethernet connection to provide internet connectivity via MS Loopback connector.

Currently the test environment, once working will be transferred to another machine on an appropriate IP range which will connect via a separate internet line to avoid any conflicts but i need to know how to get the Vmware sessions talking to each other
