Server cannot be found dns error

[Martin911]

I have a domain controller (Windows 2000) and an exchange 2000 server on the same domain on my lan. Both of those computer are behind a firewall.

I have configured a port forward for users from the internet to access this Exchange server trough Owa but they cannot access it from the internet. The server is configured to use port 80 and ive check in IIS everything is fine.

If i try to access the OWA server from a workstation on my lan it works fine using

http://10.x.x.x/exchange

when i try to connect trough the internet i get an error i use

http://externalip:portnumber/exchange

this ask me for a login screen and right after i enter my credidential i get this error message.

I've download a documentation for troubleshooting outlook web access in microsoft exchange 2000 server but nothing from this documentation works.

If i use

http://externalip:portnumber/

i get page under construction error which is normal.

My exchange server has no problem receiving or receiving email with pop account.

I double checked to make sure i used the same dns from my windows 2000 domain on my exchange server. The information is the same.

I called my ISP to verify the problem and they said everything was fine and it had something to do on my lan for sure.

Any help would be appreciate.

Thanks a lot,

Martin

Does exchange owa not use a secure page?

ie HTTPS which runs on port 443
