Before you install a Microsoft Exchange Server gateway:
The computer from which you install the gateway does not have to be the Microsoft Exchange Server computer. This means that you can install a gateway remotely.
If your gateway is designed to operate as a service of Windows NT Server, an administrator needs to set up a Windows NT Server account with the “Log on as a service” right for the gateway before running its setup program. The documentation for your gateway’s setup procedure should make these prerequisites clear.
