SYMPTOMS

Version 3.2 of Microsoft Mail Gateway to X.400 may give this error on an outbound connection:

ERROR 3 (layer): Open failed.

The gateway failed to initialize the protocol stack for an outgoing call. An earlier message may indicate the problem.

This error may occur during an attempt to connect to a remote message transfer agent (MTA). Some possible reasons for this error are:

The remote MTA is busy and is not accepting any calls.
An incorrect X.25 number is specified for the remote MTA.
An incorrect X.25 user data field is specified for the remote MTA.
An invalid X.25 facility is specified for the remote MTA.
There are not enough logical sessions between the MTA and the EiconCard. The number of logical sessions between the MTA and the EiconCard is determined by the n parameter specified in the following command:

nabios rdr <computername> /n

To determine if there are enough logical sessions available, run the ECSTATUS program on the computer with the EiconCard.

Check whether the TP4 or the X.25 drivers are loaded. For X.25, also check whether the EiconCard server machine is running.
