 Last reviewed: September 19, 1997
Article ID: Q111664

The information in this article applies to:
  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

After a process makes several connections to another server, the following error message appears in the event log: 

   The redirector was unable to create a worker thread

CAUSE

An operation required more threads than the MaxThreads entry specified in your configuration information.

RESOLUTION

Increase the value of MaxThreads. It can be found under the following key in the Registry: 

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
   \Services\Lanmanworkstation\parameters
WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

MORE INFORMATION

Increasing the workstation services MaxThreads parameter increases the number of kernel threads that the redirector will create, thus allowing more operations to be outstanding at any given time.

The parameter can be set from 0 to 255 (the default is 17).
