swampstander,

The "limited or no connectivity" status may pertain to the dial-up adapter, as well as the "error renewing" message.

Can the 4500 still be reached from the other two machines? If it can't, what type of network adapter (in addition to the modem) is installed in the 4500? What operating system and service pack is installed? If you look at the Device Manager, what status is displayed for the device under Network adapters?

Jim

swampstander,

So the device that's malfunctioning is the modem, not the Ethernet adapter. When you attempt to activate your dialup connection, what error messages do you receive? If you look under "Modems" in the Device Manager, the modem model number and its status will be displayed. Are there any errors flagged? What's the model number of the modem? If you right click on the modem, and select Properties, and then Diagnostics, are any errors reported when you click on "Query modem"/ When did the problem begin? Were there any changes (hardware or software) just before the problem began?

Hi again Jim,

Thanks so much for your help.  I do not get a error message on my computer when I log on to the internet.  It works fine on this computer.  I checked in device manager and it says that the device ia working fine.  When I try to log on to the internet on my wife's or sons computers I just get a "page cannot be displayed" or "cannot find server" messages.  I have  ran network connection wizard a few times but have had no luck.  I get no flags by the modem in device manager.  The modem is a Conexant D850 56K V.9x DFVc Modem.  When I click query modem I get no errors reported.  I do get this " AT#CLS=? - COMMAND NOT SUPPORTED" as one of the command/ responses.  As far as what was done hardware/ software wise before the problem began, its been too long for me to remember.

Thanks again for your time.

swampstander,

The error messages you're seeing during the modem diagnostic just mean that the command that was sent to the modem isn't supported by the modem. Since the modem is in fact working, we don't need to worry about it any more.

What we do need to examine is the Internet Connection Sharing setup, and what role the D-Link router plays.

Internet Connection Sharing (ICS) creates router functionality, and DHCP server functionality, on the machine that actually has the ability to establish a connection to the Internet. That machine becomes the router and the DHCP server once ICS is installed. So the only role the D-Link router would play in that case is to act as a "hub", interconnecting all three machines on the LAN side, with nothing connected to the D-Link on the WAN/Internet side. Its DHCP server must be disabled. The two "client" machines must receive their IP addresses from the machine on which the ICS server is running. If that's not the way the D-Link is configured, that needs to be fixed. But that would not cause a setup that once worked to stop working unless the D-Link configuration were changed. You should confirm that the D-Link's DHCP server is disabled.

On your PC (the one that's running the ICS server), it would be useful to see the complete output of "ipconfig /all". That can be obtained by opening a cmd.exe window (Start/Run cmd.exe). In the window that opens, type

ipconfig /all

Then select all the output that results by dragging the mouse cursor over it with the left mouse button held down. Once it's all highlighted, click on the right mouse button. That will transfer the output to the clipboard. Then paste the output into a reply to this message.

swampstander,

Very interesting! There's no sign of the Ethernet adapter in that output! I wonder what happened to it? Does the Ethernet adapter appear under Network adapters in the Device Manager? Is it enabled? If it isn't listed in the Device Manager, is it listed in the BIOS Setup pages?

No wonder sharing the dialup connection with the other machines isn't working. The adapter needed to make sharing work has disappeared from the system's configuration! See if you can determine what's happened to the device.

Jim

swampstander,

Much better! :) The IP address listed for the Ethernet adapter is not what would be expected for an adapter that's part of an Internet Connection Sharing setup. Check through the ICS installation and troublehooting guides at HomeNetHelp.com. It looks to me like ICS needs to be reinstalled on your machine.
