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

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.

Default:This policy is not defined, which means that the system treats it as 15 minutes for servers and undefined for workstations.
