Hello again, my friends.
Sadly, it is still not working. I figured I'd do a quick rundown of what has happened and my hardware/software setup.
This might get long...but everyone is always asking for more details,so hopefully I can provide quite a few for them.
First off, we have a NETGEAR ProSafe VPN Firewall FVS336G
I have SMTP, POP, and IMAP protocols forwarded on to 10.0.0.2 (Server NIC)
Now, I have one LAN port on the router going to Port 1 of a 48 port Dell Gigabit 2748 Switch. I have port 2 from the Dell 2748 going to port 1 of a Netgear 48 24 port switch (NETSWITCH_A). I have port 3 from the Dell 2748 going to port 1 of a differnt Netgear 48 24 port switch (NETSWITCH_B). (We have two Netgear 24 port switches and one Dell 48 port gigaswitch).
*Netgear switches are dumb, the Dell has the option to be managed with VLANS and such; but the Dell switch is currently in UnManaged Mode. (Dumb)
Now, we have 20+ computers, printers, and other devices hooked to all three different switches. Keep in mind that the internal network is functioning fine routing between the three switches.
PowerEdge DELL server. Runs 64bit SERVER2003 OS. The server is the AD (domain.local), the DHCP server for the network, and the DNS server for the network. All devices seem to use the server2003 DNS server without problems. The server also runs Exchange 2007.
The server has 4 gigabit network cards. They are named Internet (10.0.0.2), VPN(10.0.0.9), and TEAM 1(10.0.0.3) *Team 1 is a teamed network connection that teamed two other gigabit network connections....for a total of 4 server NICS.
The Internet NIC is hooked to port 4 of the Dell Switch
The LAN1 NIC is hooked to port 5 of the Dell Switch
The LAN2 NIC is hooked to port 6 of the Dell Switch (Remember LAN1 and LAN2 are teamed as TEAM1)
and VPN NIC is hooked to port 7 of the Dell Swich
My exchange server works beautifully while using POP or IMAP from within the LAN or outside the LAN.
While setting up exchange (instead of IMAP) I get an error saying that the exchange server is not running or is not accessible.
I am setting up outlook exchange account on the client by going to Start| Control Panel | Mail and then I click on Email Accounts and add a new email account. For the server I type in mail.domain.com and for the user name I put the name of the mailbox. I then go into more settings and under the Connection tab I click Connect to Microsoft Exchange using HTTP and inside the Exchange Proxy settings, I have the following:
checked Connect using SSL only and checked Only connect to proxy servers that have this principal name in the certificate. Then I have mttd:mail.domain.com
I have On Slow Networks checked and have selected NTLM Authentication. (I have also tried Basic)
When I go to connect I usually get an authenication box asking for username and password. I enter all the data right Username: DOMAIN\Pault and my password. Once I click OK on the authentication box, it pops right back up...over and over and over.
On the server under the exchange management console, I have enabled Outlook anywhere for address mail.domain.com and have tried both NTLM and Basic authentication.
Also, I enabled RPC over HTTP on the server and the services SEEM to be running. I also setup split DNS, which also seems to be working fine.
*Another tidbit is that my server's name is server.domain.local, I don't know if that causes a problem with it not being .com?!?
I have installed a ssl certificate from GoDaddy onto the default web site in the IIS 7 server. The certificate is for mail.domain.com
If I goto a web browser and type in https://mail.domain.com I go to a site that says the certificate was verified and the basic IIS screen saying that the page is Under Construction. (I don't get a certificate error anymore...I'm guessing that means I installed it right)
Also, I am able to telnet to mail.domain.com on port 25 and 143.
I neglected to mention this earlier, but my client machine is using Outlook 2007 with all the latest updates. And my Exchange server is also fully updated.
Well, the only other thing I can think to tell you is my setup for out web address.
a record for @, Mail, and webmail that points to out external IP address
cname record for www that points to @
MX record that points to @ for the host and goes to mail.domain.com (priority 0)
And, in case I didn't cover it earlier, the port mappings on the router are:
http to 10.0.0.2 (internet NIC on server)
https to 10.0.0.2 (internet NIC on server)
SMTP to 10.0.0.2 (internet NIC on server)
IMAP to 10.0.0.2 (internet NIC on server)
POP to 10.0.0.2 (internet NIC on server)
Now, I think that is all the information I can think of to give. I am getting a lot of pressure form my bosses to get this done, (Not really negative pressure, because they know I'm not a trained tech or network admin) but I am completely stuck and have no idea what to do next.
I might be at the point where I need to hire someone to come in and sort through these last few problems...but they are really expensive. So any last thoughts or ideas from you guys would be much appreciated. Thanks for your help so far.
(sorry it is so long, hopefully I've given you guys enough information that you can help me hunt this down)
