Migration from Exchange 2003 to 2007 External OWA problems

I just recently migrated from Exchange Server 2003 to 2007. Right now I have both boxes running and connectors between the two setup. I made the changes to our PIX and internally to route the mail to the 2007 box and it is working correctly. When I test the internal OWA (https://mail.server.com/owa) I go right to the page with no problems. When I try to access it externally I get a "Page not found" errror from IIS, but it is the IIS 6 from the "old" mail server. I have made all the internal DNS changes to point to the 2007 box and mail is flowing through the 2007 box but I can't get external OWA to point at the box! Any ideas on what I am missing?

Hi,

I supose you have done it but have you updated the port forwarding in your pix to point to the new server ( public wan:port 443 ->  exchange 2007:port 443)

What do you have publish the website? with two versions of exchange working you need two diferent web publish rules. The diference will be, in case of beeing isa server publishing the website, in the path, because exchange 2003 owa access is trought the /exchange path and exchange 2007 is trough the /owa. Create 2 publishing rules and report the result.

hope it helps.

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Yes changed the line in the PIX to point the Internal IP address of the new mail server "access-list external permit tcp any host 192.168.42.78 eq https". I am assuming that this is the line that you are talking about?

I should mention that I don't need the two OWA sites to Coexist, I just need OWA 2007 to work correctly so I can move all the users over from the 2003 box and then decommission it.

Is there a pointer somewhere else that needs to be changed?

Antonio VargasMicrosoft Senior Cloud ConsultantCommented:
that line you wrotte is not a redirection line. it's one access list line. the allow traffic. you need to reconfigure the nat entry. it's still pointing to the old server because the nat entry was not changed. you did well on creating one access-list but also change the nat entry. the pix is the only thing that publishes services? dont you have one web service machine in the dmz or one isa server? if not.. do it in the pix.

The Static NAT rules on the PIX were changed as well.

Any other ideas?

Antonio VargasMicrosoft Senior Cloud ConsultantCommented:
if nat rules are correct you should be redirected to the new iis on the new server. if you are going to the old one double check the rules.

I checked again, they all look correct:

static (inside,outside) tcp interface smtp 192.168.42.78 smtp netmask 255.255.255.255 0 0
static (inside,outside) tcp interface www 192.168.42.78 www netmask 255.255.255.255 0 0
static (inside,outside) tcp interface pop3 192.168.42.78 pop3 netmask 255.255.255.255 0 0
static (inside,outside) tcp interface https 192.168.42.78 https netmask 255.255.255.255 0 0

Antonio VargasMicrosoft Senior Cloud ConsultantCommented:
yes they look ok. you have only changed the https rule? if so maybe a reboot to enable the config or one enable runing_config command can solve this

doboszbAuthor Commented:
I changed all four of the above rules to point to the new Exchange server because they were pointed at the old one previously.

doboszbAuthor Commented:
I took a look and the running config has the changes I made...

Any other thoughts? Could it not be a firewall issue?

Andres PeralesCommented:
have you ran a clear xlate command on your pix?

doboszbAuthor Commented:
That did it! Thank you so much!
