Hello,

Neither Windows Server 2008 nor Windows Server 2012 has a direct equivalent to the open-files parameter in Linux that limits the maximum number of open file descriptors. In Windows, handles are used instead of file descriptors, and there is no straightforward way to set a hard limit on the number of handles a process can open.

To manage resource usage in Windows, you can take the following summary steps:

Monitor Handle Usage: Use tools such as Resource Monitor, Performance Monitor, or PowerShell to track handle usage and identify processes that are using a large number of handles.

Optimize Applications: Review and optimize your applications to ensure they are not opening unnecessary handles. Close handles when they are no longer needed to free up resources.

Increase System Resources: If possible, increase the available system resources, such as memory and CPU, to accommodate higher handle usage.

Configure Automatic Actions: Use monitoring tools to set up alerts or automatic actions when handle usage reaches a critical level. This can include restarting processes or notifying administrators.

Remember, managing resource usage in Windows requires a combination of monitoring, optimization, and configuration to ensure system stability and performance.
