The connection to Microsoft Exchange is unavailable

I am running Microsoft Outlook 2010 and I am trying to connect to Exchange Server 2003.  When I try to add the exchange account, I get the error:
The action cannot be completed.  The connection to Microsoft Exchange is unavailable.  Outlook must be online or connected to complete this action.

Is there a simple fix for this?

The computer on which you have Outlook 2010, is it on the domain and are you trying to configure Outlook for the user account that is logged in.

Have you tried manual configuration of Outlook as oppose to Automatic? Try Manual Configuration and see does this make a difference.

Can someone tell me what this means and how to do it.  It seemed to work, I just don't know what it means:

Hi,
did you try manually adding the exchange internal ip address in the host file on the machine.

The error seems to be with name resolution. what is the DNS server entry in your client machine NIC. set the local DNS server as the primary and the internet DNS server as the secondary.

you can also try flushing the DNS entries

Check the IP settings fully. The Exchange will be part of a Domain and therefore nslookup should respond with the AD Domain server name (DCname.DonmainName.Local)
If not, then your primary DNS address needs to be set to the AD Domain IP where your inhouse DNS must be working.
To test this theory you should be able to set the exchange connection in Outlook to the IP address of the exchange server, put your name in and click [check name] button. If that works then DNS is the problem.

Sorry OSheila, the link I provided is relating to Outlook 2003.

Is this happening on all machines or just one or two machines? Have you tried reinstalling Outlook on one machine to see if this solves the problem?

Only happening on one machine.  Tried re-installing and it didn't help.

@ OShiela, in relation to your last comment.

There is a host file on every machine, c:\windows\system32\drivers\etc\hosts
In the host add the ip address of the DNS Server for example Server Name= ExchangeServer and IP Address= 192.168.1.2 - it would look like this in the host file.

ExchangeServer      192.168.1.2

Certainly check the ip schema on this one machine, and make sure the ip schema is the same as the other machines on your network. Try flushing the dns cache on the machine. Go to the command prompt and type
ipconfig /flushdns and then press enter

ipconfig /registerdns and press enter again.

Thanks JBond, when I entered: ipconfig /registerdns

it responded with: The requested operation requires elevation.

On the PCs in question, at the command prompt type

netsh winsock reset and then restart your PC.

If this does not resolve the issue try giving the PC a static ip schema. I presume that the PC is configured for DHCP?

Then see if Outlook will work.
