set up is as follows: ADSL MODEM (bridged mode) -> Linksys Wifi router (does PPoE authentication and has static WAN IP, DHCP is OFF, Wifi A.P.) -> Lan Switch -> client computers and 2003SBS with 1 NIC.

the router's ip is 192.168.1.1
the server's nic ip is static 192.168.1.5  / subnet 255.255.255.0
server nic gateway: 192.168.1.1
server nic dns 192.168.1.5

DNS on the SBS box eventually points to att DNS servers ( 205.152.132.23 & 205.152.144.23)

DHCP is active on SBS and allocates leases on 192.168.1.15-200

This is a new install of SBS as of this afternoon, but i am at the same point i was yesterday...

If i ping from the SBS, i can't ping the router (time out)
firewall is disabled

i can ping machines that are connected to the network (not yet connected to the SBS domain)
i ran IEICW but nothing changes... recreated all DNS and DHCP setups still no no avail

any ideas as to what I am overlooking ? I have done this before and I don't know what I am doing wrong right now :-(

Er - is PING the only thing that doesn't work? Can the SBS box access the internet?

Coz some routers are (stupidly) configured NOT to respond to ping.

If you *can't* access the 'net, then check

IPCONFIG - see what other info is in there that may be conflicting
ROUTE PRINT - check that the default route points at the router and that tehre isn't something giving you a second default route.

Does the router have diagnostic tools - can IT ping the server?

no no internet access on the server... forgot to mention that...

router responds to ping, as i can ping it from client machines

ipconfig shows same ip info i mentioned above

i have to check route print will do that tomorrow

router is quite simple i'll see if it can ping tomorrow as well...

Did you run the Configure E-mail and Internet Connection Wizard in the to do list?  If not, you really need to do so.  Click on start, click on server management, click on to do list and then click on the #2 Connect to the Internet which will launch the wizard.  Good luck, Rob.

Sorry I missed that you ran the wizard, should have known what you meant!  This is a bit of a long shot and haven't really spent the time looking at this for you that I should as I have been very busy (tax day.)  But I recall Broadcom having an update to the driver that was needed for some people after a service pack update or windows update.  It is very vague in the back of my mind but figured it was worth mentioning... check for updates to the network adapter as that is worthwhile regardless of my crazy head.  Good luck, Rob.

another thing i've noticed is that local machines connected to the same network are visible on the network. i have updated the broadcom driver but nothing changed. i can ping by hostname so if i do ping accounting  it pings 192.168.1.102 which is correct, and i can see the machiens in net neighborhood...

yet if i try pinging 192.168.1.1 , the att dns, or anoy outside address, even by ip, it times out

The Route and IPConfig outputs all look just right.

The ONLY other thing I can think of...

I installed a network last week and used a set of Level-1 "managable" switches coz they were PowerOverEthernet and I needed that to power up the client's new IP phones. I didn't need the "management" stuff on the switches so I never even looked at it.

I wish I had - coz I realised later that the default IP address on the new switches is 192.168.1.1 - so when I plugged in their new WiFi access point to try to configure it... I was talking to the Switch. And because both devices were tryign to respond it took ages to re-configure the switch to a new IP so it didn't clash with the AP. (Esp as I had TWO switches!)

Could there be ANYTHING at all on your network other than the SBS machine which is configured to 192.168.1.5 ?


Quick way to tell, on a workstation that has TRIED to contact the server recently, type "arp -a" - the MAC address in the table for 192.168.1.5 should be 00-1D-09-FE-41-64 (i.e the same as the IPConfig output above!) - if it's anything else, something else on your network is reporting in as being on 192.168.1.5.


One more test to try - on the SBS box go into Network config, configure the Broadcom card, TCP/IP, Properties, Advanced, and add a *second* IP address to the card (say, 192.168.1.254 255.255.255.0) (do NOT add a second Gateway). Then see if you can access the server via the second address.


Have you run the Security Wizard yet?

Have you tried these tests with the Windows Firewall on the SBS turned off? Have you installed any third party "software firewall" on the SBS?

You might try running

http://technet.microsoft.com/en-us/sysinternals/bb897437.aspx

on the server and seeing if it reacts at ALL when you try to access the server from the 'net.
