OWA not working after changes on public IP address

Hi There,

The network setup is:

Technicolor router (public IP)
Draytek Router (WAN2-DZM)
Windows 2008 R2 (single domain, GC, DNS, DHCP, Exchange 2010)

The draytek was the original router and everything was working fine inside and outside the network.

By mistake the ADSL connection on Draytek was terminated and we have to use the technicolor box instead. The Draytek is connected to Technicolor LAN3 port and setup as DZM.

Since the public IP has changed, I have amended the mx records with the new IP public IP of technicolor.

MX webmail.domain.com

I've used MX Tools website to test the MX record above and it seems to be fine.

I have also amended the A records to new IP address:

webmail.domain.com  public IP
autodiscover.domain.com public IP

From inside and outside the network I can reach the OWA page, but after entering the correct credentials I receive the following error:

HTTP 500 internal server error

Is there a problem with the certificate or am I missing some ports to open/forward between routers?

Thanks,

Do you get the error from both inside & outside network?

Check this: http://www.msexchange.org/blogs/walther/news/exchange-2010-sp1-experiecing-an-owa-http-500-error-554.html

Have you tried accessing owa virtual directory from the IIS manager in the sever itself?

Try using  https://testconnectivity.microsoft.com/

This should help where the break is at. Good luck.

yes the error was from inside & outside network.

I rebooted the server without joy.

Looked at your link.

Yes the service Microsoft Exchange Forms-Based Authentication was down, manually started and BINGO I can log on from inside and outside the network.

But if I hit 'New Message' another error is displayed.

HTTP Status Code: 500


Thanks.

From inside or outside?

If from inside, go to individual CAS server, Open IIS Manager, Naviagte to OWA Virtual directory & browse to see the results
