There is a chance that I have found some WMI bugs on Server Core that
make working with WIN32_NetworkAdapter and
WIN32_NetworkAdapterConfiguration classes quite challenging.
Specifically the following properties are always empty:
- WIN32_NetworkAdapter :: NetConnectionID (the name of an
interface as it appears in control panel)
- WIN32_NetworkAdapter :: NetConnectionStatus (well, without it
you cannot check whether an interface is online or offline) - something
that you need when turning DHCP on a specific interface - if the
interface is offline, calling EnableDHCP method on
WIN32_NetworkAdapterConfiguration instance will result in the interface
getting a static IP (0.0.0.0) with subnet mask of 255.0.0.0
Currently I can only test it on WMWare - any chance anyone can verify
this on a real box ? You do not really need to run any scripts - just
execute:
C:\>Wmic nic get name,netconnectionid,netconnectionstatus
For IP enabled interfaces you should see something like:
Name
NetConnectionID NetConnectionStatus
Broadcom NetXtreme 57xx Gigabit Controller Local Area
Connection 7
Dell Wireless 1390 WLAN Mini-Card Wireless
Network Connection 2
VMware Virtual Ethernet Adapter for VMnet1 VMware
Network Adapter VMnet1 2
VMware Virtual Ethernet Adapter for VMnet8 VMware
Network Adapter VMnet8 2
If NetConnectionID and NetConnectionStatus are empty, you are also
subject to the issue.
TIA,
Guy
