Mac ARA: AppleLink Gateway Conflicts with ARA

The communication program in the AppleLink gateway will not function correctly with AppleTalk Remote Access (ARA) version 1.0. If ARA is installed on the server with an AppleLink master gateway and the communication program in the AppleLink gateway tries to initiate a call, the following error message will occur:

ARA utilizes the Serial Port Arbitrator to check if the serial port is in use before attempting communication. The AppleLink gateway does not recognize the Serial Port Arbitrator and tries to use the modem port directly. To avoid this problem, put the AppleLink gateway on another server that does not have ARA installed. If an alternate network connection exists such as EtherTalk or TokenTalk, ARA may be moved to the printer port which will leave the modem port available for AppleTalk exclusively. This solution however, requires a modem for both the gateway and ARA.

Microsoft has confirmed this to be a problem in version 3.1 of Microsoft Mail for AppleTalk Networks. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
