Exchange 2k

I have exchange server setup on a remote Win2k Advanced server which is also acting as the DC. I have tcp/ip filtering setup on the server. What ports do I need to allow for exchange to work correctly?
Do i need to open ldap, rpc etc?

Any help would be appreciated.

No. What are you trying to get remote access to, just mail?? Then it's SMTP port 25.

You can also do a text search of this page for any port number you want: http://www.ietf.org/rfc/rfc1700.txt?number=1700

Let me be a little more clear....
Exchange 2000 on Windows 2000 Advanced Server
Server is Domain Controller and Global Catalog server.
Server is not DNS.
Port 25 (smtp) and port 110 (pop3) are both open.
What other ports need to be open for Exchange to work?
I know that other ports need to be opened because if I turn off tcp/ip Port filtering everything works fine! Its only when I filter that problems occur.

I would open ports 110, 143, 25, 80 and 389.

MSGeek-
I tried 110, 143, 25, 80 and 389 but the Microsoft Exchange System Attendant will not start with only these ports open.
Any other ideas?

MSGeek

Is that the same problem you had when you turned port filtering off, I don't recall you saying anything about the System Attendant?
