SYMPTOMS

When you try to start the Monitor service from the Command Prompt or from the Control Panel Services tool, you receive the following error:
Could not start the monitor service on SERVERNAME. Error 2002 - the window style or class attribute is invalid for this operation.
Monitor.exe is a command-line utility that ships with the Microsoft Windows NT version 3.51 Resource Kit. Monitor.exe controls the Data Logging Service that performs the same function as the Alert and Logging facility in Performance Monitor. You can schedule the Datalog.exe file to start automatically using Monitor.exe and the At.exe commands, but you must start the Performance Monitor manually.

CAUSE

This error can occur if one or more of the following is true:
  • The Monitor service cannot locate the workspace settings (.pmw) file that it was configured to use.
  • The workspace settings file (.pmw) was saved in Chart view or no objects were added to monitor.

RESOLUTION

The workspace settings file (.pmw) must reside in the %Systemroot%\System32 directory. It also must be saved in Log view, not in Chart view.

The .pmw file is a Performance Monitor workspace file that saves current Performance Monitor objects and counters to be used with the Monitor and Datalog utilities. For more information on these utilities, see the Microsoft Windows NT Resource Kit documentation.
