Bug #: 8388 (SSCE)



SYMPTOMS
When a network connection that connects a Microsoft Windows CE-based device to a network is disconnected, a Microsoft SQL Server 2000 Windows CE Edition 2.0 connectivity application that is running on the Windows CE-based device may stop responding. The SQL Server CE 2.0 connectivity application returns no error messages.

Note The connectivity application may be a replication application or a Remote Data Access (RDA) application.



CAUSE
This problem occurs because the Windows CE-based device may experience many periodic failures when communicating through a network. To work around these periodic failures, the SQL Server CE connectivity component is designed to retry network connections. Therefore, even though the network is disconnected while a replication method call or an RDA method call is made, you may not receive an error message, and the connectivity application stops responding.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



Apply the hotfix
 On the Windows CE-based device, replace the following SQL Server CE files with the corresponding files that are included in this hotfix:  Ssce20.dll (SQL Server CE Engine) Ssceca20.dll (SQL Server CE Client Agent)

Notes  When you deploy your SQL Server CE 2.0 connectivity application from Visual Studio .NET, the SQL Server CE files are installed in the &quot;Program Files\SQLCE 2.0&quot; path.</li> When you deploy your SQL Server CE 2.0 connectivity application from Microsoft eMbedded Visual Tools, the SQL Server CE files are installed in the &quot;\Windows&quot; path.</li> When you develop an application in a mixed environment that contains Visual Studio .NET and eMbedded Visual Tools, you must replace the files in both paths. You can replace the files in the path where the application was last deployed.</li></ul> </li> On the computer that is running Microsoft Internet Information Services (IIS), replace the Sscesa20.dll (SQL Server CE Server Agent) file on the appropriate virtual directory.</li> Perform a soft reset of the Windows CE-based device.</li> Restart IIS on the computer that is running IIS. To do this, run the iisreset command at a command prompt.</li></ol>
