Hi all,

I have just recently set up a domain, currently with only one server. It is set as the DNS server also, with forwarding to our external ADSL DNS. Everything else is working fine, browsing, loging on, accessing shared files, etc. is all great but outlook wont send/recieve. It says it cannot connect to the server, check port and SSL settings.

Before now the DNS of each PC was set to that of out ADSL ISP which caused logging in and shared file access to be extremley slow, amoungst other problems, but outlook worked.

Now that our local server is the DNS, everything works perfectly, loggin's and shared access is instant, but outlook will not send/recieve on any PC.

Thanks in advance for any and all help.

Does your mailserver resolve correctly when you ping it? Perhaps there's something buggered up with that record on your internal name server.

Try clearing the DNS cache using ipconfig /flushdns.

are you using exchange and it is part of your domain or are you using an external account? is the server on your LAN or different location. are you using POP3 or MAPI

Thanks for the quick reply.
The situation actually is that we currently do not have a mail server. i.e. were just useing the one provided by our web site host. The workstations were connecting directly through the ADSL connection to the hosts mail server. This is all I need to get working, at the moment I dont need a mail server or any server side mail control at all. Just a standard everyday outlook/web server connection like you'd use at home. I think the problem is actually more likley an issue with the ports/dns setup. When I open the DNS config on the server, it includes services for "_tcp" and"_udp" but I can't find pop3 or smtp anywhere. I also get a problem when I try to connect to a website control pannel via http on port 8443. This makes it seem like the dns is not properly forwarding for certain ports... maybe...

I dont think this would be the problem as the problem is the same on several workstations (all with email access) al using different accounts and datafiles.

As above we dont actually have a mail server at the moment.

I tried /flushdns as you suggested on the workstation and server and the problem is still the same.

Did you name your windows domain the same as your internet domain?  Like for example is your mail server mail.company.net and your internal windows domain is company.net ?  If so there will be an internal dns entry for company.net which is now screwing up your mail.  If that's the case then I'll explain how to create the dns entry you need.

Problem Solved.

I added the external mail server to the list of hosts in the DNS, so its IP address could be resolved from our DNS server.

Thanks anyway for the ideas.

You hit the nail right on the head... just about the same time I did :)
I found your comment when I posted my last one... so...
But I'll give you the points anyway, good job, and now this info is at least out there to find for others... unlike it was this morning :)
