Hi David,

Thanks for using the SBS newsgroup.

>From your description, I understand the issue to be: users can not browse
internet or send mails from the SBS server. If I am off base, please don't
hesitate to let me know.

For your current situation, let us check the following settings and
verifying them to see if the issue be fixed.

I. Please ensure proper binding order of the network adapter cards. The
internal network card should be at the top. The detail steps:

Connections page.
2. Click Advanced in the menu and click Advanced Settings in dropdown list.
3. Under the Adapters and Bindings tab page put the internal Nic at the top
in Advanced Settings page.

II. Please check DNS and Gateway settings. Please ensure the following
settings:

1. Leave the Default Gateway of the internal NIC blank of the server box.
2. Configure the internal client computer's NIC and the internal NIC of the
server box to use the internal DNS Service (the internal NIC IP) as the DNS
Server. And there is only the DNS server be configured on client computers.

III. Please ensure enable NetBIOS over TCP/IP on client computers, please
check the settings.

1. Right-click My Network Places, and then click Properties.
2. Right-click the external network adapter''s Local Area Connection icon,
and then click Properties.

4. Click Advanced.

6. Click "Enable NetBIOS over TCP/IP".
7. Click OK, click OK, and then click OK.

IV. Please try to clean IE cache, temporary files on client workstations
and the server box:

To clean IE cache on all domain computers, follow the steps:

1. Launch Internet Explorer.
2. Click the Tools menu and then click the Internet Options item.
3. On the General tab, click the "Delete Files" button in the Temporary
Internet Files area.
4. Click to add a checkmark to the "Delete all offline content" item and
then click OK.

6. Click the "View Files" button, and then remove all the files in the
"Temporary Internet Files" folder. Then close the folder.
7. Click the "View Objects" button, and then remove all the objects whose
status is "Damaged". Then close the folder.
8. Click OK twice to close the dialog boxes.

To clear ISA cache: url cache. You can find the file by default in:

After check above settings and verifying them. Then please Re-run CEICW to
refresh network connection. It is greatly recommended that you take a look
at the following KB article to get detail steps to configure network
connection:

Please ensure you have chosen appropriate connection type, FQDN and e-mail
server type.

Then please test the issue, what is the result?

If the issue persists, please help me collect some information to isolate
the issue:

1. What is your meaning of "All our outgoing connections die after 1 minute
10 secs."? How you know this? Could you describe more detail to the issue?
What is the error message you received when you attempted to browse
internet? Can you help me collect some screen shots to the symptom?

2. Does the issue also happen on the server box? Please try to browse
internet from the server and tell me the result. Please also test ping and
nslookup this time, what is the result?

3. Have you installed any third party anti-virus or firewall on the server
box or client workstations? If yes, please disable them all and test the
issue again, what is the result?

4. What is the version of the ISA server? How you enabled the VPN facility?
In SBS environment, you just need setup VPN server using Configure Remote
Access wizard.
