Microsoft network server: Amount of idle time required before suspending a session


This security setting determines the amount of continuous idle time that must pass in a Server Message Block (SMB) session before the session is suspended due to inactivity.

Administrators can use this policy to control when a computer suspends an inactive SMB session. If client activity resumes, the session is automatically reestablished.

For this policy setting, a value of 0 means to disconnect an idle session as quickly as is reasonably possible. The maximum value is 99999, which is 208 days; in effect, this value disables the policy.


  • 15 minutes for servers.

  • Undefined for workstations.

Configuring this security setting

You can configure this security setting by opening the appropriate policy and expanding the console tree as such: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\

For specific instructions about how to configure security policy settings, see Edit security settings on a Group Policy object.
