We have exchange server 2003 setup in our office and we have everything working great, except of the laptop users. The exchange server address should be mail.ourcompany.com, but when we put this in and select 'Check Name', it automatically reverts to server1.mail.ourcompany.com. Not a problem except for the laptop users. Once they leave the office, they get password errors and if we change it to mail.ourcompany.com, it stays like that until they return to the office, and then it reverts again. I'm sure I'm missing something in DNS or Exchange Server settings...any help or direction would be greatly appreciated.
