Hi, got what might be a problem with DECnet on the DECstation Ultrix.

Environment
-----------
        An Alpha OpenVMS server displays x-windows using DECnet as transport
        protocol to a DECstation5k25 (40MB mem) Ultrix 4.2a client installed
        with DECnet.

        The Alpha and the DECstation are on the same segment.

        The DECstation is used as trader workstation, mounting NFS drives
        and receiving multicast (broadcast and point-to-point) network
        traffic - some of which are market data which updates continuously.

Encountered Problem
-------------------
        Significant and visible (and irritable) delays on updates to the
        windows displayed from the Aplha server occurs often - but not
        continuously.

Troubleshooting
---------------
        Sniffer shows that the DECstation often does not ACK and the Alpha
        retries however then timesout and continues to the next transmission.

        This then occurs again because the results are not displayed in the
        window and the user initiates the Alpha server to do the same
        procedure again.

        The user initiation does not occur from the DECstation, rather a
        separate device attached to a DECserver (async terminal server) via
        the LAT protocol. There does not seem to be any problem with this
        circuit.

Assumed Conclusion
------------------
        Most of the technologists feel it is the DECstation that is the
        cause of this problem (hard for me to believe).


Would anyone be able to help or have any ideas, this is all too new to me.


Sincerely yours, Leslie
