Your network connection may be reset when you try to perform a file operation on a remote Windows Server 2003-based computer (843515)

SYMPTOMS

When you perform a file operation on a remote Microsoft Windows Server 2003-based computer, such as saving a file from a local Windows Server 2003-based computer, the remote computer may reset the network connection during the operation.

For example, when you perform a Microsoft SQL Server database-backup operation on the local server, you can specify a location on the remote server to store the backup file in. However, the backup operation may not be completed successfully in this scenario. Additionally, events that are similar to the following may be logged in the Application event log: Event Type: Information

This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. Event Type: Error
Event Source: MSSQLSERVER

CAUSE

This problem occurs if a client Server Message Block (SMB) redirector connection on the Windows Server 2003-based computer that is running the SMB service is not initialized correctly. When a new client or the server itself creates a new SMB session to the server that is running the SMB service, the server may not correctly determine whether the SMB session request is made by the new client or by the existing client. If the server incorrectly determines that the existing client made the new SMB session request, it resets the network connection for the existing client.
