Re: msft 169.254.173.250 IP address

Right....thanks a million guys for all your input to this.

Frog, I checked the Gratuitous ARP option on the CCM and it was not enabled.
Thanks for that anyway buddy!

Farouk, thanks for the pointer. I think it was my IP phone internal switch
acting abit dodgy, cauing the delay for the PC NIC to become enabled. I
changed my IP phone and all seems to be working as expected right now.

Ryan, yes, that was a mere typo. Its 15secs and not 15mins.
