If you use HTTP to connect to an instance of Microsoft SQL Server 2005 on a computer that is running the original release version of Microsoft Windows Server 2003, the HTTP connection may time out and may end unexpectedly. This problem occurs after the instance of SQL Server 2005 receives the SQL Server data that you sent as an HTTP request over the HTTP connection.
The timer in Http.sys is the kernel mode driver that handles HTTP requests in Windows Server 2003. This timer is not reset correctly after the instance of SQL Server receives the data as an HTTP request. Because the default connection time-out period is set to 120 seconds, the HTTP connection times out and ends if SQL Server 2005 takes more than 120 seconds to process the client request and to send the processing results as an HTTP response to the client.
To work around this problem, you must increase the connection time-out value of the Web sites on the computer that is running Microsoft Internet Information Services (IIS). For example, if IIS is installed on the computer that is running your instance of SQL Server 2005, follow these steps on the computer to increase the connection time-out value:
