Active Directory Connector problem

I'm trying to set up an Active Directory Connector agreement between Windows 2000 Server ADC and Exchange Server 5.5. (This is in preparation for upgrading to Exchange 2000). I get an error (IDno: c103aa1a) "The Exchange Server specified in the Connections page is invalid".
It isn't an invalid name so what could be the problem?

You need to assign the LDAP protocol in Exchange Administrator to a different port.  Put it on 388.  AD uses the same port as the LDAP service and they conflict.

Check which LDAP port your Exch 5.5 Server is currently using, then change the LDAP port on the Connections tab of the Connection Agreement properties to the LDAP port number that Exchange Server is currently using.

To check on Exch 5.5:

1. Start the Exchange Server Administrator program.
2. Under the server name, click Protocols.
3. In the right pane, double-click LDAP
4. Check the LDAP port number that is displayed on the General tab.

Now make sure the same port is specified on the Connections tab of the ADC's connection agreement properties.

This should be something other than 389. 390 is popular.

Thanks for the suggestions. Having changed the port (geoffryn and spherion you gave the same advice but geoffryn was first!) I now get "Unable to contact the Exchange server, please ensure that your connections are configured correctly"

I'm sure the suggestions were correct as far as they went. It didn't solve my problem, but I've now got round the problem by doing a fresh intallation of Exchange 2000 on another server. We'd hardly started using 5.5 so it won't matter. Geoffryn was first, but I don't know how to award the points!

What if the protocol ldap does not show up in Exchange 2003? How do I add the protocol into exchange?
