Hello Job,
Thank you for posting here, and thanks for Larry and SuperGumby's input.
According to your description, I understand that your internal clients do
not get IP address from SBS. If I have misunderstood the problem, please
don't hesitate to let me know.
Based on my research, we do not need to configure the DHCP or DNS on SBS,
we only need to run the CEICW. The CEICW will enable and configure the DHCP
and DNS on SBS automaticlly. I suggest we try the following steps to see if
we can resolve this issue:
1. Run the Change Server IP address wizard to configure the SBS IP:
a. SBS->Server Management->Internet and E-mail->Change Server IP Address
b. Change the IP to a new IP address and then run the wizard again and
change the IP address back.
c. Test this issue.
2. Please rerun the CEICW to make sure your SBS 2003 server have right
network configuration. Go through the follow KB and Rerun CEICW carefully.
How to configure Internet access in Windows Small Business Server 2003
http://support.microsoft.com/kb/825763/en-us
Detailed steps for your reference:
One network adapter - manual router connection to broadband
a. On the Connection Type page, click Broadband, and then click Next.
b. On the Broadband Connection page, under My server uses, click A local
router device with an IP address, and then click Next.
c. On the Router Connection page, next to Preferred DNS server and next to
Alternate DNS server, type the IP addresses that are provided by your ISP.
In the Local IP address of router box, type the IP address of the router
that the server uses to connect to the router.
d. Click to select the My server uses a single network connection for both
Internet access and the local network check box, and then click Next.
e. A message may appear that warns that the firewall that is provided
cannot be configured. You are offered a chance to view information about
configuration settings for an existing firewall device.
f. On the Network Connection page, click Server Local Area Connection
under the Connection Name.
g. Click Next.
h. Complete the Configure E-mail and Internet Connection Wizard.
Then, the DHCP and the DNS will be configured correct.
3. Please disable any other DHCP server in LAN. Ensure you do not enable
DHCP on router and other clients.
4. We should connect SBS and client computers with switch but not router.
The router will block the traffic between SBS and clients. Please replace
the router with switch.
If we cannot resolve the issue after we perform the above steps, please
help me collect some information for further investigation:
1. Run command "ipconfig /all > c:\ipconfig_sbs.txt" and "route print >
c:\route_sbs.txt" on SBS, send the files c:\ipconfig_sbs.txt and
c:\route_sbs.txt to me at v-terliu@xxxxxxxxxxxxx
2. Run command "ipconfig /all > c:\ipconfig_client.txt" and "route print >
c:\route_client.txt" on problematic client, send the files
c:\ipconfig_client.txt and c:\route_client.txt to me at
v-terliu@xxxxxxxxxxxxx
3. Can you ping SBS IP address from clients?
4. Do you install any firewall on SBS?
5. Gather MPS network report on SBS:
a. Download MPSrepot_network from
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
15706/MPSRPT_NETWORK.EXE
b. Run MPSRPT_NETWORK.exe on the server box.
c. The tool will automatically collect the information. This procedure will
take 10~15 minutes.
d. Open Windows Explorer, navigate to the folder:
%SystemRoot%\MPSReports\Network\Reports\Cab\
e. Send the .cab file directly to me at v-terliu@xxxxxxxxxxxxx
I hope these steps will give you some help.
Thanks and have a nice day!
Best regards,
Terence Liu(MSFT)

| Network:
|
| 1. (teh internets)
|
| 2. Power Super Router
|
| 3. SBS (local DC, DNS, DHCP, Exchange and misc M$ f00) on the same level
are
| all clients.
|
| And YES, SBS IP == DNS!!! (before anyone asks).
|
| I dont believe in DHCP, I think its one of the lazy shortcuts that will
| eventually doom humanity - however as it supposedly fixes all DNS keys
and
| strings that have outdated IP numbers (since we changed the server IP
after
| we hooked it up to the router) I did it anyway. So, I enabled DHCP.
During
| this process I followed atleast 5 or so excellent guides on setting up
dhcp
| server - (all were however ripped copies of one Ms Technet). Well, I set
up a
| scope and Verified the server en restarted it and guess what.
|
| No clients can connect.
|
| Setting STatic IP:If I connect with router ip as gateway, server ip as
dns I
| still cant ping my server. Ths is some DNS error?
|
| Any ideas?
