If there are difficulties with starting an invokable TP, there may be a mismatch between the information for the invokable TP, the invoking TP, and/or LUs in the SNA Server configuration. That is, there may be a mismatch between the symbolic destination parameters, the registry or environment variables, and/or LU aliases specified in SNA Server Manager. For details about how to specify LU aliases in SNA Server Manager, see the Microsoft SNA Server Administration Guide.
