Strange IP Address Behavior

Hello--

We run a W2003 environment and host our own websites on an IIS server within
our subnet.

Our web developers use different internal IP addresses in their web page
host headers and the corresponding IP addresses are statically configured
into the IIS server's TCP/IP properties of it's NIC card.

It seems all of a sudden, the NIC card started with the bouncing yellow ball
and states it is acquiring a network address. But, it has a static address
already in it.

I have flushed DNS, rebooted, etc, etc. Everything works fine, but when I
look at the support tab on the NIC properties, it shows all zeros for the
addresses.

Again, everything works, but this is a puzzle for me. Why would it say it is
acquiring a network address when it has a static address?

Any help would be appreciated. Please don't flame me if you need more
info--just ask.

Thanks.

Hello razor,

Sounds like there is a problem with the NIC or something; maybe see if there
are some updated drivers for it? Obviously, it is not working properly if
it is all of a sudden registering all zeros.

I'll take a look. It is a relatively new NIC card--but thanks.

Hello razor,

Something else to check - there could be an IP address on your network with
the same address as this server. You can use tracert, WINS and or DNS to
find out if that is the case. Maybe take a look at what IPs are being given
out by DHCP? Any laptops coming into your network? I had a case where someone's
home wireless was the same as my subnet and when they logged into the network
every morning, it would kick my phone system offline.

I meant to say it would kick my phone system offline because the laptop's
IP address was the same IP address as my phone system...I had to make sure
to tell this user that she has to make sure to turn-off the laptop wireless
connection before reconnecting it to the our network.

Yea, that's a good one to check. We do have laptops leave the LAN and then
reconnect--sometimes months later.

Thanks again.

I did a trace route and it all looks good. I will try to update the NIC
drivers off of production hours and see what happens.

Hello razor,

Bummer - perhaps someone else will have a good suggestion!
