SYMPTOMS

If you have the Internet Locator service (ILS) installed in BackOffice Small Business Server (SBS) 4.5 or BackOffice Server 4.5 and the ILS is using TCP port 389 (which is necessary for Microsoft NetMeeting clients to connect), some of the console wizards may not work.

For example, the Add User Wizard may skip past the information necessary for creating the Microsoft Exchange mailbox, or you may receive the following error message and events when you try to manage your e-mail distribution list:

E-mail Distribution List Wizard
The specified Exchange server could not be found or is not running. This program cannot continue.

Event ID: 1306
Type: Error
Source: MSexchangeDS
Description: Register LDAP protocol failed with error 10048. If port number 389 is used by another application, change to an unused port, then shutdown and restart Microsoft exchange Directory Services. Contact Microsoft Support service if the condition persists.

Event ID: 1309
Type: Error
Source: MSExchangeDS
Description: Register LDAP SSL protocol failed with error 10048. The LDAP SSL server is not available. Make sure port number 636 is not used by another application.

CAUSE

When you run the Add User Wizard from the console, it attempts to make a Lightweight Directory Access Protocol (LDAP) query to the Microsoft Exchange server on TCP port 389 (by default). The ILS may start before the Exchange Directory service, which would take control of TCP port 389.

RESOLUTION

See the following article for information about how to configure Exchange to use a different port, allowing the ILS to use TCP port 389. The Add User Wizard can query Exchange on the alternate port.
