accessing webmail if internal DNS is down RRS feed

  • Question

  • currently I have exchange and owa setup in my internal network.

    users can access the webmail via https://mail.company.com. this domain name has a public Internet IP address from ISP.

    How can my users access the webmail via the same domain name if there is network outage in my internal network ?

    eg. AD and DNS server is down. currently if there is network outage, we will direct users to access the webmail via the public IP address.

    any suggestions is welcome

  • Hi,

    Users should not be able to access webmail if AD is down - Exchange server won't run without AD

  • Hi,

    It's difficult to access anything if name resolution does not work, but if they can resolve the url for the webmail you must just communicate that fact to the users - maybe via an intranet page or??

  • Hi

    Test to reach it through the IP address if it's very critical..

    https://xxx.xxx.xxx.xxx/owa or /exchange if it's Exchange 2000/2003

  • If DNS is down, the domain name will not be resolved. Then, OWA and other client will not be accessed normally.

     

    Thanks.
