PRB: DLC Protocol Is Not Supported by Microsoft Cluster Server 1.0

 * }

Q189986

-

The information in this article applies to:


 * Microsoft Windows NT Server, Enterprise Edition version 4.0

-

SYMPTOMS
When you try to make a DLC printer a failover resource in MSCS, a print job might hang in the spooler and cause other unexpected behaviors.

CAUSE
Microsoft Cluster Server only supports failover of the TCP/IP protocol because of its ability to flush the Mac address. The DLC protocol talks directly to the card in the printer and cannot be flushed during a failover.

RESOLUTION
Do not install the DLC protocol on a computer that needs to failover a printer that does not support the TCPIP protocol.

STATUS
This behavior is by design.
