Athif, when running forestprep (or any time you reference the Exchange server in setup), are you using the following nomenclature: SERVERNAME:LDAPPORT? It would look like: EXCHANGESVR:389. This is assuming that Exchange is actually listening on port 389 (previous messages have all the info needed to check); modify the port number accordingly. Some other obvious things to check: can you ping the Exchange 5.5 box by name from the box you're trying to install Exchange 2000 on? Is WINS running on your network? Exchange 2k requires it (believe it or not), so try installing it and run setup again. If you install WINS on a box other than the Exchange 2k box, be sure to modify the Exchange 2k box's TCP/IP settings to reference that server. Is DNS working well in your organization? Make sure that everything in your DNS zone that should be there is: references to the domain controllers, etc. You shouldn't need to modify your hosts file at all if DNS is working as expected. -- Greg Lara ---------------------------------------------------------------------------- --------------------------- This e-mail message may contain privileged, confidential and/or proprietary information intended only for the person(s) named.

In my scenario, the Exchange 5.5 is on NT4 which is acting as a BDC. I am trying to install a new exchange 2000 in same site and i am getting this error, Setup encountered error while attempting to bind the Exchange Server "Servername:0xC103FC93(64659): could not bind to the Microsoft Exchange Directory Server,SERVERNAME. The Microsoft Exchange Server computer doesnot respond" The machine on which i am trying to install e2k is also an Additional Domain controller. How do i troubleshoot this error? Any suggestions. Thanks again, Athif
