SBS ICS Wizard unable to configure Networking, and related issues.
Posted on 2006-04-20
I Installed SBS 2003 without ISA on a computer with 2 nics. The computer was setup quickly and ran fine for months in the same configuration as I had no time to fully setup the system and I had no static ip adresses. The setup at that time was very simple; the external nic obtained its ip address automatically from a Westell modem, and clients obtained ip addresses from via DHCP on the SBS, and everything resolved and worked fine. The ICS wizard worked fine setting this up. The SBS machine was able to browse the internet as well as the clients. Then, Bellsouth (our isp), issued us a Netopia 8 port DSL router and 5 ip addresses excluding the router’s LAN ip. I switched out the modem for the router and left the default configuration on the router active. This also worked fine. Now, I needed to setup, Exchange and IIS and get the server fully working, so I reconfigured the router, nics and SBS as follows: I disabled DHCP on the router, gave it its starting static ip address and set the router to expose any other static addresses in that range. I turned off address mapping (NAT) and set connection state to always on. Entered the username and password and connected. The browser interface says line status was up and ok. External adapter was setup with one of bellsouth's issued ip addresses and I set it up using the ip address of the Netopia router as the gateway and Bellsouth’s issued dns servers. The internal network adapter was configured with a static ip of 192.168.16.1 on a 255.255.255.0 mask, and the DHCP scope was setup to issue a range of 192.168.16.2 thru 192.168.16.254 . DNS and wins were also installed on this machine. DNS was setup using Bellsouth’s DNS servers as the forwarding addresses if it could not resolve locally. I ran the ICS wizard and got some errors when setting up the network but all other areas in the wizard (email, firewall, certificate, etc.) worked fine. I reran ICS wizard, choosing different broadband options, and lost internet access on the SBS machine, and got errors in the networking part of that wizard as well. I now cannot get clients or server to browse the internet, although ping does work. SBS ICS wizard cannot configure networking no matter what broadband options I choose. The only way I can get it to do anything, is to reconfigure the ICS Wizard even though it fails with the PPOE broadband option. The SBS machine then is able to browse the internet, but clients still cannot. I had configured another machine using the same ISP and basic setup and it ran fine. I have tried to duplicate configuration of the working SBS on the NON working one, and still nothing. The best I get is browsing the internet on the SBS server (only) using the PPOE option, but that is not even the configuration I used on the first machine that works! And the VPN Wizard hangs at the very end every time I run it. What am I missing here? I have read all the config posts, and I cannot get past this. Is it reinstall time?
