Outllook/Exchange Killing me slowly - HELP PLEASE

Post by bom » Fri, 06 Sep 2002 22:15:51



Could someone please help me with this issue - I'm about to go crazy.
I have been working it for about 3 months now with no resolution, it's
a good thing my job does not depend on this.
My situation - I have Exchange 2000, an ISA server, a 2000 domain
controller all on seperate boxes (all with latest SPs) attached to a
switch attached to a router (doing NAT) with a static IP, DNS is
split-split also running locally. The Exchange box is a securenat
client to the ISA.

The Exchange box is published via secure mail server on the ISA.
Internally Outlook XP or 2000 conncet to the Exchange server with no
problem, it is connecting from an external source over the internet
via mapi that does not work. Outlook comes back with "Outlook cannot
log you on.........................Work Offline to work locally until
the server becomes available"
I have reloaded TCP/IP as per one Q article, I have added registry
hack - NO RFR Service, I've rebuilt exchange onto another server,
rebuilt ISA as well, opened and closed various ports on the router,
currently open are 135, 137, 138, 139, 25, 80, 443, 110, 119.
I can manually SMTP into exchange from external sources and also
manually SMTP out from with my domain. Mail is delivered into exchange
okay as well.
My ISA Logs tell me that the connection from outside is being made ok
(snapshot of IP and FW logs below) and is accepted.

I've read Tom's book and all articles I can find back to front but I
guess I am missing something. Can anybody give an insight into whats
gone wrong.
I know VPN is another way but not for this project.

Thanks

1. Exchange sending mail slowly...PLEASE HELP

We are testing a copy of Exchange 2000, and when I go to
send a message it will take OWA and Outlook at least 5
minutes to tell us we have a new mail.  I can keep hitting
the send and receive button as well and nothing happnes.  
When the message does arrive, it says that it was recieved
the same time I sent it, or instantly which should


12:00 just when I sent it.  Is there a reason that could
be casuing this delay?
