CSC 486/586

2

Overview

• VMWare Networking Features– VMNet0 (Bridged), VMNet1 (Host-Only),

VMNet8 (NAT)– DHCP Server settings

• Disabling

• Determining a restored machine’s original Static IP

3

VMWare adapters???

• VMNet0 (Bridged)– Put’s VM world on the “live” network and VM obtains

a DHCP address from the physical network’s DHCP server (if addresses are available)

• VMNet8 (NAT)– Put’s VM world on the “live” network and VM shares

IP of physical host machine. Does not obtain a DHCP address from the physical network’s DHCP server

• VMNet1 (Host-Only)– Limits networking connectivity of VM world to

communication with the host machine and any other VMs running on host machine.

4

VMWare Virtual Adapters• Host only (VMNet1) should always be used for restored

machines• If you wish to adjust VMNet1 settings and it’s DHCP

settings…

Original IP address – from registry

• Which registry “ControlSet” was last used and/or is the default control set?

• What cards/adapters were installed?

• Where they static or DHCP IPs?

• What were the descriptions of those physical network cards installed?

• What was the static IP address assigned to the old physical network adapter?

9

Windows Registry - Which Control Set???

10

Windows Registry – Static IP

11

Windows Registry – DHCP IP

12

1. Right-click on “GUID” and select rename

2. Do NOT change anything, just use short-cut keystroke “CTRL+C” to copy the GUID name into memory.

3. Select the main top branch of the registry (My Computer)

4. Select Edit/Find from the Registry Editor menu

5. Paste the GUI into the “Find what:” box using the shortcut keystroke “CTRL+V”, then click the “Find Next” button.

6. Hit “F3” every time the search stops, to continue the search until you find the physical description

Which GUID is for which adapter???

13

Some other registry locations (there are many):HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\{CCC9204F-BBD5-434D-8BBF-9A3592B2BD9A}\Connection

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\{CCC9204F-BBD5-434D-8BBF-9A3592B2BD9A}\Parameters\Tcpip

Which GUID is for which adapter???

14

Re-assigning old static IP• Once you find the IP for the old physical network

adapter in the registry, assign it to the new virtual AMD PCNet adapter.

15

Re-assigning old static IP• If you got the right IP, you will get the below message.• The default selection is Yes, but you will click the “NO”

button.

16

You are done!!!

• You may or may not have to reboot the server to restart all server functions (DNS, DHCP, Active Directory, etc.) so they are working correctly.

• Workstations should now pick up DHCP addresses from the restored DHCP server and be able to communicate with server/client software.

17

So why did we do this???• Because until you get it configured correctly, these screenshots show the

issues relating to services on the server not running until you correct it.

Questions???

Use the discussion board, as usual…
