Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi,

Thanks for your update.

According to your description, I understand currently you can not schedule
a non business time to temporary remove 3rd-party software on your Small
business server.

So please perform the following steps on SBS box.

1, Open ESM, expand Server---Server Name-Protocols-SMTP, right click
Default SMTP Virtual Server,
2. On General Tab, make sure 127.0.0.1 listening on 25 port. Or you can
select All unassigned.

In addition, I suggest you rerun CEICW to configure your SBS. To do so:

1. On the Small Business Server 2003 computer, click "Start", and then
click "Server Management".

2. Expand "Standard Management", and then click "To Do List".

3. In the right pane, click "Connect to the Internet", and then click
"Next".

4. On the "Connection Type" page, click "Do not change connection type",
and then click "Next".

5. On the "Firewall page", click "Enable firewall", and then click "Next".
Important Do not click the "Do not change firewall configuration" option.

6. If you receive the following message, click "OK":

To ensure the proper configuration of ISA Server, existing custom packet
filters will be disabled. For information on how to re-enable existing
packet filters, see Small Business Server Help.

7. On the "Services Configuration" page, click to select the check boxes of
the additional services that you want to make available from the Internet,
and then click "Next".

h. On the "Web Services Configuration" page, click "Allow access to only
the following Web site services from the Internet", click to select the
check boxes of the services and of the Web sites that you want to make
accessible from the Internet (i.e. Outlook Web Access, Remote Web
Workplace, Outlook Mobile Access, Outlook via the Internet, Business Web
site (wwwroot), etc.), and then click "Next".

8. On the "Web Server Certificate" page, click "Create a new Web server
certificate", type the Small Business Server computer's fully qualified
domain name in the "Web server" name box, and then click "Next".

[Important] The fully qualified domain name that you type in the "Web
server name" box must be the same name that you use to connect to the Web
site from the Internet. For example, if the URL that you use to connect to
a Microsoft Outlook Web Access Web site is
<<https://external.domain.com/exchange>>, type "external.domain.com"
(without the quotation marks) in the "Web server name" box.

Note: If you don't have your own registered fully qualified domain name
(FQDN), we can input the "Public IP Address" (As you mentioned the [valid
IP address]).

9. On the Internet E-mail page shows, select "Enable Internet e-mail" and
click Next.

10. Select either "Use DNS to route e-mail" or "Forward all e-mail to
e-mail server at your ISP". If you select the latter, enter the ISP SMTP
server. Click Next.

11. Specify to receive e-mail using one or both of the following methods:

- POP3 Mailboxes
- Exchange

Click Next.

12. Enter your e-mail domain name and click Next. The e-mail domain name
should match the mail exchanger (MX) resource record maintained at your
ISP. This must be a registered Internet domain name.

13. Go through the steps to finish the wizard.


14. On the "Completing the Configure E-mail and Internet Connection Wizard"
page, view the configuration information to make sure that it is correct,
and then click "Finish".
