In a Microsoft Host Integration Server 2010 environment, after you configure and save a static IP selection in the user interface for the IP data link connection (IPDLC) link service configuration, the configuration is not saved.

For example, in a system that has a static IP address, you add an IPDLC link service. You select Static IP address, and then you select the desired static IP address in the drop-down list. After you save the setting and reopen the IPDLC link service, you see that the Local Address field is blank.

Additionally, when you view the following registry subkey, the value “2” is assigned as the registry value for AddressType, regardless of the setting changes that you make to the IPDLC link service configuration:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNAIP1\Parameters\ExtraParameters
