Why won't Outlook connect to Exchange?

We just replaced a XP box with a new Windows 7 64bit box. I joined it to our local domain and setup Outlook to receive mail via our Exchange Server. It is the same setup I used on the XP box and all was working. Now I can not get the new Windows 7 box to connect to the exchange server in Outlook. I tried to connect to the exchange server by mapping a drive letter to it just to see if I could actually connect to it. I was prompted for username and password and could log on with the users info. Without logging out or restarting I tried Outlook again, it prompted me to enter username and password (which it accepted) but still would not connect to exchange. I restarted the computer, logged in as the user, went to map a drive letter to the exchange again, and when prompted I logged in with the domain admin username and password and then tried Outlook, it prompted me for username and password, I used the users login credentials and it worked. All looks and runs great until restart. Then I have to follow the same login with admin username and password first. It seems to me like a security restriction somewhere, but I'm just guessing. Any assistance is appreciated.

Are you sure when you are logging in that you are logging into the domain and not the local workstation? I know is sounds minor, but has gotten me before.

Good question, but I am logging with domain\username and the usernames password. Also, I did check in Outlook to make sure I was not Offline. I forgot to mention that the windows 7 box will, on occasion show a balloon asking for the latest credentials. Please logout and enter your latest credentials.
I'm not at that computer right now so the balloon message may be similar, not necessarily exact.

it seems like your computer is not a member of the domain, or it has the wrong dns servers on its network card (either hard coded or by dhcp)

take a look at the dns settings (ipconfig /all) and make sure they are your correct one(s)

when you map a network drive, it shouldn't ask you for a password.

on the other side of the fence, your windows firewall could be blocking certain domain functions from reaching the workstation - you might try disabling the windows firewall and see if it's cleared up.  if so, make some custom allowances in it, or just leave it disabled for the junk that it is.

I would join your workstation back to a workgroup reboot and then rejoin to the domain.

What I was asking was when you logged into the PC after logging off or rebooting, are you logging in local account or the domain?

Commented:
make sure you are able to access local intranet
Add the domain to dns sufix and try accessing outlook
Exchange 2007 uses Autodiscover so it should not prompt you for a login/pass when configuring your outlook to connect to exchange. It should be passing your domain login credentials to exchange and automatically configuring your account. I would try as one user suggested. Go back to a workgroup, reboot and rejoin the domain. If your using SBS 2008 open up IE and go to https://connect to join the domain.
