ISA 2004 Stopping Blackberry OWA access with default last rule

I have recently changed the A record for the public facing OWA address. Since then the ISA server is denying any further blackberry connection attempts. All was fine before the A record was changed. I can see the default last rule denying the HTTPS requests in the logging. Not sure why though.

ISA 2004 SP3
Exchange 2003

Thanks

Are you surprised?

Define what you mean by changed the A record - the IP address of the record or the FQDN?
If it is the name, have you got new certificates? Are these imported into ISA and associated with the web publishing rule listener?
Has the updated certificates been pushed to the respective Blackberry hand-helds?
Have you re-run the publishing wizard to rebuild the rule?

I have changed the IP address of the record, not the host name. I have not re-run the publishing rule. I'm using the same certificate as before. Do I need to re-run the web publishing rule?

Should be OK - unless you had more than one ip address on the external interface.

For example, I have 5 external IP addresses on my external FTMG server (FTMG being the latest version of ISA). When I publish my internal services to the outside you need to create a listener. By default, ISA/FTMG will use ALL the external ip addresses OR you can select the ip address to use from that list. Not sure if this applies to you or not but if it does - and you have changed the IP address that is associated with the service then the service listener will require amending.
