alternate IP configuration bug?

alternate IP configuration bug?
Hi! I have a peculiar problem with my workplace network. It is not a DHCP,
so in the wireless adapter IP settings I have manually entered the IP etc.
as an "alternate configuration". When first connecting to that network, I
get the appropriate address and everything is fine. But when I disconnect
somehow (leaving and returning, sleep mode, ...), I get an IP in the
169.254.x.x range, which of course does not work. The only way to reconnect
is either to restart the computer or to manually enter another IP address in
"alternate configuration". When I disconnect/reconnect the next time, I need
to enter a third (different) IP.
It seems that Vista somehow remembers the IP as taken and does not reissue
it to my adapter on a reconnect. Is there any remedy for this behavior?
Thanks!

Re: alternate IP configuration bug?
Hi Ken! Thanks for your quick reply.
If I understand correctly, each time I want to connect to that network, I
have to manually clear all IP settings and enter the static IP of my
workplace network? So, having an automatic configuration with DHCP enabled
and an "alternate configuration" with static IP is not working? Will there
be a patch soon?
Actually, I think the article you gave me is not 100% describing my problem,
because instead of remaining wih the alternate IP address, Vista issues a
private IP (169.254.x.x) after the first disconnect to the DHCP-less network
(but it takes the correct settings for Gateway and DNS).
Thanks for your help
Thomas Jones

Re: alternate IP configuration bug?
From your post "...Vista issues a private IP (169.254.x.x) after the first
disconnect to the DHCP-less network... ".
If you have auto configuration checked each time the computer starts and
does not "find" a DHCP source private IPs are assigned to both initial and
alternate configuration settings.
You state "...have a peculiar problem with my workplace network. It is not a
DHCP, ...". If DHCP is not being provided why is auto configuration
selected and why are you using the alternate configuration setting and not
the settings in the "General" dialogue box?

On the "alternate configuration" tab, you can choose between "automatic,
private IP" and "user defined IP". I need "user defined".

Did I mention, this is a laptop with WLAN. Generally, I connect with DHCP.
Only when I am at work, I need to use the fixed IP. As this usually happens
each day, I don't want to manually enter the whole config each morning.

Re: alternate IP configuration bug?
Sorry, Ken, no it does not. The article tells me to remove IP settings and
configure a static IP address.
I need, however, DHCP usally and static only when at work (alternate
configuration).

Although the configuration is entered correctly, Vista issues the fixed IP
only on the first connect after a reboot. On the second connect it issues a
private IP 169.254.x.x, which it shouldn't. This is obviously a bug.

(My workaround - because I did not want to reboot every day - was to enter a
second static IP. This works once, then I need a third one, etc. It seems
that Vista internally remembers these IPs as already in use, until the next
reboot.)

Best regards
Thomas

XP and Vista fall back to that address range as a self-asigned one,
when no DHCP server is found ("limited connectivity" etc.).

So to hold a static IP, you'd want to prevent Vista from looking for a
DHCP server that isn't there. I'm not too sure how the logic works,
i.e. whether Vista will fall back from the "front" DHCP settings to
the "alternate" fixed-IP. It may also be confounded by a gateway IP
that persists, so that Vista asks the gateway for an IP, doesn't get
it, and then falls back to "limited connectivity" instead of static IP

Ahh... that could be a different kind of bug ;-)

I often wonder if PCs see themselves as if they were different PCs on
the same LAN, when the same PC has different IP addresses. If so,
then it may not assign the same static IP as it could clash with what
is assumed to be another PC on the LAN that may not be running or
plugged in yet. You can see the problem there.

There's another issue with alternate IP, and that is where the PC is
reached by name (as SQL services sometimes use), then the name is
mapped only to one of the multiple alternative assignments.

A cheap fix may be to add a second network adapter and set each
adapter to different IP strategies. May be cheaper than butting your
head against it for days on end :-)

Sure.

Yep, that is, when you have selected "automatically assigned, private
IP-address" on the "alternate configuration" tab. Then, a private address in
the 169.254.x.x range is and sould be assigned. If you enter a static
address instead, this one is selected. This worked fine under XP. Under
Vista, this works only on the first connect after a reboot. (This is a
laptop, so I move around, so there is more than one connect.) On the second
connect, Vista assigns a private address.

An even cheaper fix would have been not to install Vista at all....
(Sorry, but I am a bit frustrated with all these Vista bugs and driver
problems.)

And, thanks Ken Zhao for bringing this issue to the attention of the
programmers.
