RE: SBS2003: Intermitent Connectivity from Clients to Public websi

Thanks so much for you reply. I had come down with the flu and have not been
able to respond until now.
I already had two zones set up under the Forward Zones. I did create a third
primary in Forward Zones. Also, I don't understand why I need the secondary
and Stub zones, so I have done nothing with them. I input the DNS domains
names along with their respective IP addresses per DNS name.
DNS1.comcastbusiness.net with IP address XXX.XXX.XXX.XXX
DNS2.comcastbusiness.net with IP address XXX.XXX.XXX.XXX
The SBS Server's network cards are configured per your specifications for
internal and external NIC.
I originally set up the users and computers using the wizard and
subsequently have never had a problem with this.
Originally, I did install ISA Server, but uninstalled it. I would like to
use it, but have heard horror stories.

Hi Hans,

Thank you for posting in SBS newsgroup.

From the description, I understand the issue to be: you get intermittent
connectivity when you access internet web sites from client computers,
however, you can access them normally on SBS. If I have misunderstood your
concerns, please do not hesitate to let me know.

To narrow down the problem, would you please help me confirm if you have
followed the general steps to configure SBS and client computers?

On SBS:

1. Leave the Default Gateway of the internal NIC blank.
2. Configure both the internal NIC and the external NIC to use the internal
DNS Service as the DNS Server.
3. On the DNS Server, create the DNS Forwarder to forward the external DNS
resolution requests to the ISP's DNS server. See:

323380 How to configure DNS for Internet access in Windows Server 2003
http://support.microsoft.com/?id=323380

4. Strictly followed the instructions in the KB article below to run CEICW:

825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763

Then, you can bring all the computers from "workgroup" to "Domain" as
following:

1. Make sure the client computers get the IP addresses and DNS
configurations from the SBS 2003 DHCP service correctly
2. In Server computer, Create a user account and computer account for each
user by using the Add Users and Computers Wizard
3. Log on a client workstation using its local administrator account
4. In client computer, open IE and run http://servername/connectcomputer
5. Follow the wizard to finish.

If you have done so, please help me collect the following information for
troubleshooting:

1. Do you have ISA installed on SBS?
2. Does the situation occur on all client computers and all internet web
sites?
3. Can you ping server name and IP of SBS form client computers?
4. Please post ipconfig/all results on SBS and client computer.

You can also refer to the following KB article to see if there are any
network connection issues between SBS and client computers:

325487 How to troubleshoot network connectivity problems
http://support.microsoft.com/?id=325487

I am appreciated your time and look forward to hearing from you.

Best regards,

Crina Li (MSFT)

rocket,

HELP!!!
| Server Configuration: I have three network cards of which one is disabled.
| The server acts as a firewall and NATS is static ip address on one
network.
| The public card has:
| Static IP from ISP (comcast) XXX.XXX.XXX.XXX
| Primary and Secondary DNS addressses
| Subnet Mask:255.
| Gateway:
| My internal network card Configuration:
| IP address: 10.20.30.1
| Subnet: 255.0.0.0
| Gateway: 0.0.0.0
