RE: Warning: Multiple default gateways are intended to provide redunda

Hi:
Thank you for posting here.

>From the description, I understand that you receive a warning information
when you open the TCP/IP properties. The network diagram is like the
following:

Internet---Cable
Modem---Router(192.168.100.1)----Switch----(192.168.100.2)SBS Server

If I am off base, please feel free to let me know.

First please help to confirm if the warning occurred when you click "OK" to
save the TCP/IP configuration or when you double click the Internet
Protocol (TCP/IP)?

To narrow down this issue, please help to gather the following information:
1. Do your SBS Server and clients have internet access after the warning
appears?

2. Please first restart the router and the switch. Then perform a clean
boot on the server. A Clean Boot will allow us to isolate any device
drivers or programs that are loading at startup that may be causing a
conflict with other device drivers or programs that are installed in your
computer.

A. Click Start, click Run, type "msconfig" (without the quotation marks)
and click OK.
B. Select "Selective Startup" and remove the check box for "Load Startup
Items".
C. On the "Services" tab, click Enable All.
D. Check "Hide all Microsoft Services", click Disable All and clear "Hide
all Microsoft Services".
E. Click the OK button and then Click Yes to restart your computer.

3. Double click network adapter from the Network Connections and click
Properies. Then double click the Internet Protocol (TCP/IP) and click
Advanced. On the Advanced TCP/IP Settings page, please double check if
there are any other default gateways listed. If so, please remove them and
click OK.

Does the problem persist?

4. You mentioned that you were not able to run the Change Server IP Wizard
before. After you reinstalled the network card, can you run the wizard now?

5. If you temporarily place the SBS Server directly connect to the router
without attaching to the switch, does this problem occur?

6. In the Event Viewer, have you found any corresponding event logs? If so,
please post the event log to me in the reply for further analysis.

7. If the problem persists, please type ipconfig/release from the command
prompt, and then change the IP address to the previous one:192.168.16.2.
Please also change the IP address of the router to the same subnet of
192.168.16.1. Does this problem reoccur?

Thank you for your time and cooperation. Please feel free to let me know if
you have any questions or concerns.

Have a nice day! :)

| I get following message when I go to Network connections and right click
| local area network properties and right click TCP/IP properties:
|
| Warning: Multiple default gateways are intended to provide redundancy to
a
| single network such as and Intranet or the Internet. They will not
function
| properly when the gateways are on two separate, disjoint networks (such
as
| one on your intranet and one on the Internet). Do you want to save this
| configuration?
|
| Single NIC in this server.
|
| The configuration:
| Server IP: 192.168.100.2
| Subnet Mask: 255.255.255.0
| Default Gateway: 192.168.100.1
|
| When we originally built this server we attached it to a Linksys
| switch/router using high speed cable Internet access with the following:
|
| Server IP: 192.168.16.2
| Subnet Mask: 255.255.255.0
| Default Gateway: 192.168.16.1
|
| We discovered we needed to change the Linksys switch/router configuration
at
| the new office. We attached the server to a Linksys unmanaged 24 port
switch
| and an Adtran 612 Total Access router using a full T1 with the following:
|
| Server IP: 192.168.100.2
| Subnet Mask: 255.255.255.0
| Default Gateway: 192.168.100.1
|
| I was NOT able to change the server ip using the change server ip wizard.

| So I disabled he network card and uninstalled all network services.
Enabled
| the network card and re-installed the network services. I re-ran CEICW
and
| we have internet access.
|
| One of the things I notices was every time I run CEICW I must fill out
the
| ISP [XO Communications] external DNS primary and alternate. On other SBS
| 2003 installation once I put this information in it saved it.
|
| This leads me to believe that I have something that says the default
gateway
| is 192.168.16.1 someplace which is not correct.
|
| How do I and/or where do I look for default gateways? When I use run,
cmd,
| ipconfig only one gateway [192.168.100.1 is the correct one] is displayed.
|
| I read the user guide for the Linksys SR2024 24 Port Gigabit Switch and
| could not find any reference to the switch having any IP addresses or
| gateways. It doesnâ??t; Right?
