SYMPTOMS
An application that runs in a Terminal Services environment stops running or runs slower than expected in Windows Server 2003.

This problem occurs if the following conditions are true:
 * The %homepath% directory is set in a user's Terminal Services profile.
 * The application extensively reads or writes from the Win.ini file or from the .ini files that are in a per-user Windows directory on a Windows Server 2003-based computer that is running Terminal Services.
 * The application accesses .ini files by using the GetProfileString function or the GetPrivateProfileString function.
 * The %homepath% directory references a server across a high-latency link.

You do not experience this problem when the application is running in Microsoft Windows 2000 or in an earlier version.



CAUSE
This problem occurs for applications that are hard-coded to use the %systemroot%\Win.ini file or a customized .ini file. To avoid sharing violations, these applications automatically receive a copy of the Win.ini file that is stored in the user's Terminal Services %homepath%\Windows directory. If the application accesses the Terminal Services %homepath%\Windows directory across a high-latency connection, the read and write operations may be slow. Therefore, application performance may be slower than expected.



RESOLUTION
To resolve this problem, follow these steps:  Verify that the system is experiencing this specific problem. To do this, follow these steps:  Use File Monitor (Filemon.exe) or a similar file monitoring tool to filter for the Win.ini file or for the .ini file that the application uses. Verify that the read and write operations access the .ini file in the user's Terminal Services %homepath%\Windows directory when the application is running.  Install the Microsoft Application Compatibility Toolkit. Install the hotfix that is described in this section.</li> Use the Application Compatibility Toolkit to configure the hotfix.</li></ol>

Note See the &quot;More information&quot; section for detailed information about how to perform steps 2 and 4.
