Close unnecessary network connections
The Shared Folders (SMB) server service must be able to allocate enough system resources to function properly. If too many connections are present, the service may stop responding.
To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.
To close unnecessary network connections:
Note: Closing sessions in this way will disconnect all connections from the client computer to the server. If any application is running on the client computer, data may be corrupted. Please close running applications or reboot the client computer before deleting the connection.
- Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
- Type net session.
- From the resulting list, close any unnecessary connections by typing **net session \\**computername /DELETE.
