Thanks

Firewall issues? Port 80 or 443 going to the right place for the IP used for OWA? Rule got erased? We may need more information on your setup if you said it was working before and after a power fail it stopped....

Yes I checked the entry's on the firewall and they are all there. Although i have nothing on 443 but I never have ether. I tryied reseting both the firewall and the router and I still get the same message.

thanks

Ok.. we need info..
How you access your webmail (IP or FQDN)?
Is it in a DMZ? If so, details...

details.. details.. DETAILS!! hehe.. never enough details.

443 is for SSL

Ok I will give what details that I can... We access webmail VIA IP. It is not in a DMZ. And the setup appears to be exactly the same as when it was working.

Thanks

From the outside can you run a trace route to see if it getting to your server?

Also do a reverse look up and make your name to Ip is working properly.

I imagine you already have some utilities that will do all that bit if not, you can Download Sam Spade it is a nice free utility package.

Thanks for the advise. A tracert shows the problem. It is timing out at execulink.com who hosts our domain. I assume I should call them.

Thank You

Yes, I would call them sounds like they have a DNS or Firewall issue

Glad to have been a help.

Well checked with them and still not working. Actually they are able to connect no problem. I have done some more research and it actuall seems to be just some users. Including myself. the one common thing is we are all on DSL connections using XP.... Could this mean anything. Come to think of it mine was working until I switched from dial up to DSL.


ANy more ideas out there. Someone mention I might want to tweak the MTU settings but I don't know what to set them to.

Sounds like your local DSL provider is doing something fishy. =)

Maybe they have a web proxy that doesn't work properly with OWA? I don't know how to go about testing that theory...

Did you verify that there is a valid route for the public IP and that a router was running a config that was not saved or that the static routing was taking place on an internal host that did not have it added as persistent?
