WORKAROUND
To work around this issue, before you install Exchange 2000, on the Exchange Server 5.5 computer that is used to join the site:
 * 1) Run the Microsoft Exchange Server Administrator program.
 * 2) Click to expand Organization, click to expand Site, click to expand Configuration, and then click to expand Protocols.
 * 3) Double-click LDAP Protocol to open the properties.
 * 4) Click the Search tab.
 * 5) Modify the value for the Maximum number of search results returned option to a value that is equal to or greater than the number of servers in the organization. Also, if the LDAP protocol object at the server level is NOT set to use the site defaults, you need to change the value at the server level.



STATUS
This was fixed in beta 3 and is not an issue for Exchange 2000.
