[ActiveDir] ldap ports

[Pelle, Joe]

Hello!  Can someone please clear something up for me...?  If Exchange 2000 runs on LDAP port 379 and Exchange 5.5 runs on LDAP 389 - how do they talk to each other?  Doesn't the ADC run on port 389 as well?   Scenario:   Windows 2000 domain controller GC - want to install Exchange 2000 on it...  Already has ADC (from exchange CD) installed on it and configured a two-way CA fro 5.5 and Active Directory.  I am able to replicate the ADC and get changes/updates to my Active Directory, however when I try to install Exchange 2000 it hangs at "configuring SRS database and initializing".  I have the install point to the same site the ADC is replicating with in 5.5.    So my question is this:  Do I have to change the port on E5.5 to something OTHER THAN 389?  It seems as though my 5.5 can talk to the Active Directory database and do updates but my Exchange 2000 can not talk to 5.5 (or vice versa).  Is that because I am trying to install Exchange 2000 on a Domain Controller that is also a Global Catalog?  Or is my problem completely unrelated to the LDAP ports?   Thanks in advance for you help and suggestions!   Joe Pelle Systems Administrator Information Technology Valassis / Targeted Print & Media Solutions 35955 Schoolcraft Rd.   Livonia, MI  48150 Tel 734.632.3753      Fax 734.632.6240 [EMAIL PROTECTED] http://www.valassis.com/   This message may have included proprietary or protected information.  This message and the information contained herein are not to be further communicated without my express written consent.
