SYMPTOMS
When you try to install an Exchange 2000 server into an existing Exchange Server 5.5 site, you may receive the following error message:


 * ScFindLDAPPortNumberUsingDAPI

(K:\admin\src\libs\exsetup\dapiaccess.cxx:682)

Error code 0XC103FC93 (64659): Could not bind to the Microsoft Exchange Directory server



CAUSE
This behavior occurs because the Exchange Server 5.5 computer is not using or does not have the correct Domain Name System (DNS) information.



RESOLUTION
Either configure the Exchange Server 5.5 computer to use DNS, or configure HOSTS files for the servers.



MORE INFORMATION
How to identify:

The error reports a bind issue; use LDP to bind to the Exchange Server 5.5 directory. Then, install Network Monitor and perform a trace of the bind to the server. In this trace, you will see the endpoint=success (in the packet) and bind=success; remote procedure call (RPC) bindback success or failure from remote host is not seen.

This behavior is a result of a DNS issue, which explains why there is not a bindback or bindback failure, because the request never made it from the server.
