The MAC address is the address of the NIC in the computer.

Thanks mate,
That narrows it somewhat. This is with the Netgear PCI adapters and a Vigor
2600we. I had the thought that if someone had revised one PC running ME with
the install disk from the other ME machine that it could have inherited the
same number ?
Predictably I suppose the main machine giving most hassle is a new Dell
running XP: the ME Dells fire up straight away but the XP shenanagins are
something else.

The number is stored in rom on the network card. As you saw from the link I
gave it's possible to fool XP as to what the number is, but it seems
unlikely that an OEM install would set that when there's no reason not to
get it from the actual rom.

Tell me about it. I wish I could recover that part of my life that XP has al
ready sucked up with nonsense like this.

It's not supposed to be, but when the DSL providers started getting funny
about which MAC address was used to connect the router manufacturers built
in the ability for their products to emulate any MAC as a configurable
option.

However there still shouldn't be a conflict as these are on the other side
of the router and therefore on a different network.

Wouldn't hurt to reset the router though.

Yup I thunk I got that...
So the other side of - in my case the Draytek Vigor 2600we - is the
connection to an Isp - whereas my side is the mini network of 3 machines.
Right - I hope ??

Exactly so - you got it.

Did you find the problem yet?

No solution yet. Which has been hampered somewhat by being a single parent
with two boys of 10 and 12 years. They were attempting to install a two
player version of some murderous exploit in the networked public doc's area.
I'm rather getting the impression it could be as simple as forgetting to
"apply" changes each time to each PCI card as I tour through the options.
The XP setup for networking seems to me to be a Giant step for MS and a step
backwards for mankind ? I dunno.
The Draytek manual for the Vigor 2600we is a masterpiece of illogical
English. It starts fine then on page 16 mentions that if you wish to use
your vigor with wireless supported devices you must consider configuring it
first Now I thought that could have been on page 1, maybe.
I can't think of any other reason for specifically purchasing a wireless
router other than to use it for wireless operation: but, no doubt they know
what they mean.
I'm ploughing back through notes as it did magically refect all 3 machines
an hour ago: just before I went off to kill a Wizard by pelting him with
rotten onions that is.
That leads me to believe that when I was sending messages to junior
operative 1 ( Darth Vader I think) that maybe operative 2 also got the
message and reset (applied) - or equally didn't.
I've had some help from Broadbandbuyers ( or rather comments) and one
helpfull bod from adlsguide.ord or rather their bulletin board.
He confirmed that when Draytek state " Configure a wireless network" he has
never managed to configure it by wireless connection. I've attached an old
Ethernet card and cabled it and sure enough the router updated in a few
seconds.
I equally have just received an answer from Draytek asking for logs etc etc.
It may just be me and a bent for chronological sequence in disorder but I
think the manual for the Vigor does it a quite large disservice as they lump
them all together.
Thanks for your interest and help.
Tony
