Verify That the Microsoft Exchange Server Computer is Listed in the Hosts File

The Hosts file is read every time a Microsoft Windows Sockets (Winsock) application attempts to resolve a host name. There are no #PRE options to preload entries (LMHOSTS). You can add the Microsoft Exchange Server entry to the Hosts file and then try again without having to restart Windows. The Hosts file on Microsoft Windows 95 is located in the Windows directory. On Microsoft Windows NT, it is located in the Windows\System32\Drivers\Etc directory.
