SBS2008 Exchange, OWA and RWW problems

SBS 2008 with Exchange 2007 suddenly stops receiving mail and RWW and OWA unavailable. Cannot telnet to server from external source.
Mail works internally and mail can be sent successfully via smart host. RWW and OWA also work within the LAN. Cannot see any obvious problems in event logs.
Any ideas please? Thanks

Thanks for your assistance but I have resolved the issue. As it turns out it was the ISP that suddenly decided to start blocking certain ports when they altered the billing system. I had actually called them to check initially but it was only on the fourth call they admitted or realised it was being done.

If everything is working internally, and your not able to telnet from the outside, send or receive email or access RWW, it sounds like something is blocking the services. I would first reboot the server, make sure it is fully patched, run the SBS best practices and fix any errors and then reboot the router/firewall.

Thank you, The server is fully patched but not running Service Pack 2 for Windows Server 2008, it has been rebooted twice and so has the router.

There are a few warnings that relate to user accounts not showing up in the SBS Console. These were created for the print/copy/scanner over 12 months ago. It mentions Service Pack 2 is not installed. Should I install this?

The only error is a DNS error: "DNS A resource record points to incorrect IP address The host (A) resource record points to the incorrect IP address 192.168.12.2192.168.12.31. The record should point to 192.168.12.2."     192.168.12.31 refers to the IP of the PPP adapter RAS (Dial In) Interface. This has always been the case as I have looked at this before and believe it to be quite normal for this error to show up when running the BPA. Please correct me if I'm wrong.

When I run the Mail Flow Troubleshooter from Exchange console I receive the following error which I believe may assist "Error submitting mail Mail submission failed: Error message: Server does not support secure connections."

When I run dcdiag I receive the following which I feel also relates to the problem:

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Well this is fairly dissappointing. 4 days since my last post and it seems that this one has slipped through the cracks and been abandoned by all the gurus out there. Why am I paying for this subscription? Doesn't anyone have any ideas?

The Experts did not provide the resolution and only provided one possible solution which I responded to immediately, inidcating that was not the solution. The problem was then left sitting for a further four days without any Expert suggestions being added, during which time I found the resolution myself.
