I have a Windows Exchange 07 and all my users are using Outlook (2k3, 2k7, 2k10). Every time I need to reboot the server for maintenance, their Outlook lost the connection, but when it's back online, it's asking for credentials.
The problem is, the default login is myDomainServer\login instead of myDomain\login, I don't understand why it's using my server name by default instead of the domain name.
I'm sure it's something easy and stupid but I just can't find it :(
Thanks for your help !
