Hi all

question of the day.

I have a DHCP Server on windows server 2003. I have only one scope, and here ar the options on the scope:

from 192.168.101.100 to 192.168.101.250.
Default Gateway (Router)
192.168.101.1.

DNS   192.168.101.6
WINS 192.168.101.6.
since I have a DSL line that we are not using I thought of making it as a second Default gateway.
I gave it address of 192.168.101.87, which worked fine, for my note book with XP Pro in. however the 2000 machines are not getting the second gateway even after I release and renew the ip config.

notebook ip config (Dynamic) with XP Pro:                    another computer ip config (Dynamic) with w2k Pro:                        

IP Address:            192.168.101.180                             IP Address              192.168.101.108
Subnet mask          255.255.255.0                                 Subnet Mask           255.255.255.0
Gateway 1             192.168.101.1                                 Gateway                 192.168.101.1
Gateway 2             192.168.101.87                                
DNS                      192.168.101.6                                 DNS                        192.168.101.6                      
WINS                    192.168.101.6                                 WINS                      192.168.101.6

Any help will be very appreciated.

Add the second gateway on one Win2000 box manually to test it.  If it works, then you can do it to the rest.

I did and it worked fine, but I want it to be assigned from the DHCP server not static.

thanks for the comment. Netman66

Someone else can correct me if they want, but so far as I remember Windows 2000 does support a second gateway address assigned by DHCP and even if you add it manually I don't believe it is capable of making use of it anyway.

If you are trying to achieve a redundant setup for when you lose your DSL line I don't think this will work quite as you want.

Cheers

I'm not sure the DHCP extentions are understood the same way in Windows 2000 - I will check for you with MS and report back.

James - it will only use it if the first gateway is down.  It works sort of like DNS - if the first one is not responding it tries the second.  If the second works it gets moved to the top (not in the pane, but as order of preference).
