SYMPTOMS

Link_info

Gw_info

Link_def_info

For example, if you follow the steps outlined in the following Knowledge Base articles to build an application to monitor or retrieve status information, the application may fail to produce the expected results if the SNA Server computer is configured to use a Channel adapter.
