SYMPTOMS
You cannot find the getnamebyaddr application programming interface (API) after you configure TN3270 Server to resolve IP addresses to NetBIOS names and this process fails causing the following event in the system log:

Event 203: TN3270 server

Description:

Windows Sockets API call getnamebyaddr(xxx.xxx.xxx.xxx) failed in

function TCPSessionInitialize with return code WSANO_DATA.

EXPLANATION

An unexpected error was encountered on a Windows Sockets API call.

ACTION

Record message and contact technical support.

NOTE: xxx.xxx.xxx.xxx in the description above represents the IP address.



CAUSE
The API getnamebyaddr does not exist. Instead, Event 203 should refer to the API call gethostbyaddr.

STATUS
