SYMPTOMS
When a user logs on to a system that was upgraded from the Microsoft Host Integration Server 2000 End-User Client to the Microsoft Host Integration Server 2004 Client, the SnaBase service logs the following event:

Event ID: 1006

Source: SNA Base Service

Description: Unable to access configuration information

Action: The SnaBase service was either unable to open the configuration file or unable to initialize SNACFG.DLL. The error code from SNACFG.DLL is 2. An error code of 0 means that the SnaBase service was unable to initialize SNACFG.DLL.

Additionally, the SnaBase service does not start.

This problem only occurs when multiple users log on to the Host Integration Server 2004 Client system. This includes terminal services environments and environments where multiple users share a client workstation.

Additionally, this problem does not occur for the user who initiated the Host Integration Server 2004 Client installation to upgrade the existing Host Integration Server 2000 End-User Client. This problem only occurs for subsequent users who log on to the system and try to run the Host Integration Server 2004 Client.



CAUSE
The Host Integration Server 2004 Client does not correctly copy the required registry parameters from the  registry subkey to the   registry subkey when the SnaBase service starts. This problem occurs when users who did not perform the upgrade log on to the system.

STATUS

MORE INFORMATION
When the SnaBase service starts, the SnaBase service determines the Host Integration Server Client type. To do this, the SnaBase service examines the ClientType registry value in the following registry subkey:

If the ClientType registry value is set to Microsoft Windows 95, the SnaBase service does not copy the SnaBase registry parameters from the  registry subkey to the   registry subkey. Therefore, this problem occurs for any user who logs on to the Host Integration Server 2004 Client system after the user who performed the upgrade.

The Host Integration Server 2000 End-User Client sets the ClientType registry value to Windows 95 in the following registry subkey:

Then, the ClientType registry value is copied to the  registry subtree for each user who logs on to the Host Integration Server 2000 End-User Client system when the user first starts the SnaBase service.

The Host Integration Server 2004 Client Setup and configuration processes do not remove any part of the previous Host Integration Server 2000 End-User Client settings that exist under the  registry subtree. Therefore, the incorrect ClientType registry value exists for any user who logs on to the Host Integration Server 2004 Client who had previously used the Host Integration Server 2000 End-User Client. However, the incorrect ClientType registry value does not exist for the user who installed the Host Integration Server 2004 Client on the system.

If the ClientType registry value is set to Microsoft Windows NT, the SnaBase service copies the SnaBase registry parameters from the  registry subkey to the   registry subkey. This problem does not occur in this case.

After you apply this hotfix, the SnaBase service first examines the ClientType registry value in the following registry subkey:

The ClientType registry value in this registry subkey is updated to Windows NT when the Host Integration Server 2004 Client is installed. Therefore, the ClientType registry value will always have the correct value for the Host Integration Server 2004 Client. This prevents the problem.
