CAUSE
This problem may occur when the following conditions are true:
- Your Windows Server 2003-based computer uses the standard port monitor to control the ports for several TCP/IP printers.
- The TCP/IP printer ports have Simple Network Management Protocol (SNMP) status enabled.
When the standard port monitor prints to a TCP/IP printer, the standard port monitor uses SNMP to read the configuration of the target printer and to determine the status of the target printer. When the standard port monitor controls many printer ports, the polling scheme for the SNMP status of these printer ports is inefficient. The number of standard TCP/IP ports on a print server directly affects SNMP performance. The more ports there are, the longer it takes to clear an SNMP print-blocking error.
Additionally, the standard port monitor waits for blocking SNMP API calls to time out for each unresponsive printer.
