Tried searching the web for answers but my google voodoo isn't strong enough.
Dhcp-Client logs its events to the Windows Event Log.
To view this, open the Event Viewer, expand the Windows Logs entry on the left and select System. Here all system messages are shown.
To view only Dhcp-Client entries, click "Filter Current Log…" on the right.
In the dialog resulting from this, expand the Event sources drop-down list, and find and select "Dhcp-Client". You may want to select "DHCPv6-Client", too, but that depends on what you're trying to achieve.
