Symptoms

An SNA 3270 or APPC/CPIC application may experience a delay when you initially open a session through a Microsoft Windows 2000 Server that is running Microsoft Host Integration Server 2000. This problem occurs when you run the Win5250 emulator on Host Integration Server 2000 configured to use Active Directory.

When you enable the SNA Application full internal traces by using the Snatrace.exe tool, the following delays and error messages occur in the resulting Cliint1.atf file. (Note that some data has been omitted for readability).

Note the 2-second delay when the Active Directory interface is initialized and the 3-second delay when you connect to the WMI server running on Server5. Also, note the error message that is returned when WMI is queried, and the WMI error information taken from the Microsoft Platform SDK documentation, as follows:
WBEM_E_PROVIDER_LOAD_FAILURE 0x80041013
COM cannot locate a provider referenced in the schema. This error may be caused by any of the following:
- The provider is using a WMI DLL that does not match the .lib file used when the provider was built.
- The provider's DLL or any of the DLLs on which it depends is corrupt.
- The provider failed to export DllRegisterServer.
- An in-process provider was not registered using the regsvr32 command.
- An out-of-process provider that was not registered using the /regserver switch. For example, myprog.exe /regserver.

Cause

The "WBEM_E_PROVIDER_LOAD_FAILURE 0x80041013" error message occurs because of a system configuration problem on the Windows 2000 Server computer on which Host Integration Server 2000 is running. The Wmisna.dll file (the SNA WMI provider interface) cannot load because it is dependent on the following Wbem DLL file:
%Systemroot%\System32\Wbem\Framedyn.dll
However, this directory is not present in the PATH environment on this particular Windows 2000 Server-based computer, and therefore, this DLL file is not found.

Any retail installation of Windows 2000 Server or Windows 2000 Advanced Server automatically adds the %Systemroot%\System32\Wbem folder to the system PATH.

Resolution

From a command prompt, type "path" (without the quotation marks) to view the PATH environment setting on the computer, and then check for the presence of the Wbem folder. For example, type the following: 
C:\>path
PATH=C:\WINNT\System32;C:\WINNT;C:\WINNT\System32\WBEM;C:\Program Files\Host Integration Server\System
If the Wbem folder is not present, add it manually to your search path by performing the following steps:
1.Log on to Windows 2000 by using an Administrator account.
2.In Control Panel, double-click System.
3.Select Advanced Folder, and then select Environment Variables.
4.In the System variables window, highlight the Path variable, and then click Edit.
5.Add the Wbem folder to the beginning of the Variable value data, followed by a semicolon (;). For example: 
 Variable value:   c:\Winnt\System32\Wbem;c:\Winnt\System32;C:\Program Files\Host Integration Server\System
