In a Microsoft Host Integration Server 2010 environment, you use IP version 6 (IPv6). However, the IPv6 implementation is broken between the SNA client and the SNA Server.
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To resolve this problem, install cumulative update package 6 for Host Integration Server 2010 on all servers in the Host Integration Server subdomain. Make sure that all servers are also configured to support IPv6.
Additionally, this cumulative update must be installed on all clients that use IPv6. After this update is installed on a client, you must add the following registry value, depending on whether the client is configured to run the Resource Location component as an application or as a service.
- If you run the Resource Location component as an application, you must add the SNAIP6.DLL value to the following registry entry:HKEY_LOCAL_MACHINE\Software\Microsoft\Services\SnaBase\Parameters\Transports
The current transports should already be listed. These include transports such as SNALM.DLL and SNAIP.DLL. Add the SNAIP6.DLL value according to the order in which you want the client to use the transports.
- If you run the Resource Location component as a service, you must add the SNAIP6.DLL value to the following registry entry:HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Snabase\Parameters\Transports
Note This entry will be removed every time that you make modifications by using the Host Integration Server 2010 Configuration Utility, and the entry must then be reapplied.
