SYMPTOMSDelays may result when you print to a Windows NT 3.51 Service Pack 5 (SP5) or Windows NT 4.0 print server connected through line printer remote (LPR) to a shared printer using the Line Printer Daemon (LPD) service. CAUSE
In Windows NT version 3.51 Service Pack 4 (SP4) and earlier, the LPR
service used TCP ports 721 through 731 for LPR connections. This complied
with RFC 1179 but limited performance because it only allowed 11 TCP ports
to be in use by the service at one time. Per RFC 1122, each port must not
be reused for four minutes (2 * Maximum Segment Lifetime as defined in RFC
1122).
RESOLUTION
To revert back to the RFC 1179 specification, use the steps listed in the
appropriate section below. Windows NT 3.51 SP5To revert Windows NT 3.51 SP5 back to being RFC compliant, obtain the hotfix mentioned below or regress back to the SP4 files, by copying the following files into your %Systemroot%\System32 folder:(from the Windows NT 3.51 SP4 CD) Lprmon.dll (from the original Windows NT 3.51 CD) Lprhelp.dll Lpdsvc.dll NOTE: It is necessary to restart the Spooler service for the changes to take affect. To stop the Spooler service, type the following command at an MS-DOS command prompt: net stop spooler To restart the Spooler service, type the following command at an MS-DOS command prompt: net start spooler Windows NT 4.0 SP2 and earlierWindows NT 4.0 SP2 and earlier can become RFC compliant by applying the latest service pack for Windows NT 4.0.To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base: Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack STATUSMicrosoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4. MORE INFORMATION
With Windows NT 4.0 Service Pack 3, the default TCP Ports for LPR are 721-731.
Changes can also be made so that ports greater than 1,023 can be used
to prevent LPR from running out of available ports or conflicting with
reserved ports.
