Your DHCP server is setting the configuration.  Your internal IP addressing scheme should be serving addresses from the 192.168.x.x pool.  Look at your DHCP server (or whatever is serving these addresses) and make sure it is set up correctly.  The 192.168.x.x range is set aside for private use.   If you are using a router, it will grab the public IP and serve the internal network with private IP's.

The subnet mask is correct, but the IP's are not.  Also make sure your DHCP server is set up to serve the DNS.  This is very important.

Any questions, please ask.

The DHCP server is set up to send out an IP Range of  So it cannot be that.  These settings are in the properties on the NIC.  When it pulls down an IP address it does not show up in there.

Any other ideas?

And I thought this was going to be an easy one.  :)

Are you using a Server or Router/Firewall to push the IP's?  And I am sure you have configured your NIC to DHCP and not static...  of course you did.

Is this an IP range you purchased, or leased as Global IP's?  Just curious, as this is not a private range.

Let me think on this a little.

To answer Fatal_Exceptions questions...

Our server is pushing down these IP's.  The IP's the server is pushing down are just the non-routable internal network IP's.  Our server has a static IP that is used for internet.

Man, you got me here, Steve.  If your NIC is not getting a good IP from your DHCP server, you should get an APIPA address, not a 192 address.  It must be getting that address from somewhere.  Nothing else on the subnet acting like a DHCP server is there?  Never, never seen this happen before.  


Have to go out to dinner with Family, but I will think about it.  Maybe someone else will stop in and give it a try.

Well - guys.  You are going to laugh at me on this one.  This is a computer that is at a library and we installed a neat piece of hardware that doesn't allow anychange to the system settings whatsoever.  It is call Centrino Gaurd.  After you reboot it puts all the system changes back to the way they were before.  To stop this all you have to do it unlock the gaurd.  I never tried looking for something that easy.  Thanks for your help and sorry about slowing you down.

:)  Kind of like a mandatory profile, but with hardware?  Funny.

Just glad to see you solved the problem.  I knew it had to be something really weird.

Happy Holidays to you and yours.
