Question:
When I try to access Exchange Outlook, it produces the following message: “The Microsoft Exchange Address Book was unable to log on to the Microsoft Exchange Server computer. Contact your system administrator if the problem persists.”
I’m able to ping the Exchange server by IP address, but I never could ping the server by name. What do I do?
Answer:
Sounds like you’re having the classic name resolution problem. If it’s just that one workstation, then I’d suggest you create a HOSTS file on the workstation in the C:Windowssystem32driversetc. directory.
The HOSTS file is just a plain text file named “HOSTS” (no extension) that contains the IP address and name of your server in this format:
111.222.333.444 MyServerName
Try creating one and see if it resolves your problem.
If you have multiple machines, then you’ll want figure out why your WINS or DNS name resolution isn’t working properly for your remote users and get it fixed.
