PipeMaximum

HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters

Data type Range Default value
REG_DWORD 0x0 - 0xFFFFFFFF milliseconds 0x1F4 (500)

Description

Controls the maximum time at which the redirector "backs off" on failing nonblocking named pipe read operations.

This entry exists to prevent an errant application from swamping a server with nonblocking requests when there is no data available for the application. You can use the backoff statistics to tune this entry to be more efficient for an application that uses nonblocking named pipes (except for SQL Server applications).
