>Hello Larry,
> This code works fine for the machine on which it is running. I wanted to know of getting all the MAC addresses on the network.

>>Hi Mark,
>>Try this code. I have stared using something like it since I switched to Win2K and VFP 7 because it requires WMI (and the VFP 7 IMoniker support enhancement to GetObject is required).

>>omgr = GETOBJECT("WinMgmts:")
>>oadaptercol = omgr.InstancesOf("Win32_NetworkAdapterConfiguration")
>>IF oadaptercol.Count > 0 then
>>   * go through each adapter configured on the system
>>   FOR each oadapter in oadaptercol
>>      if type("alen(oadapter.Properties_('IPAddress').Value)") = "N" then
>>         * check was done to handle WAN adpaters that are configured on the
>>         * system however they don't have IP addresses so disregard them
>>         ? oadapter.Properties_('MACAddress').Value
>>            for each cIP in oadapter.Properties_('IPAddress').Value
>>               ? cIP
>>            endfor
>>      endif
>>   ENDFOR
>>ENDIF
>>return

>>>I have run this code multiple times on a Dell 8100 Inspiron, Win2k machine, and I get a totally different return value every time. I have found absolutely nothing that can consistently return the correct MAC address of the primary adapter.

>>>P.S. I do realize this thread is 7 months old. I am still searching for a way to do this and finally found this and other thread with the search engine.
