| Source | TN3270 Server |
| Description | The TN3270E Server has opened a socket to listen for clients |
| Event Information |
CAUSE:
When the TN3270 server calls the CloseSocket() function, the Windows NT TCP/IP address object connect handler address is set to NULL, which causes TCP/IP to send a TCP/IP Reset when clients attempt to connect to the TN3270 port number. When an SNA session becomes available, the TN3270 Server reopens the listen socket by calling the socket() function. This causes the Windows NT TCP/IP driver to create a duplicate address object with a valid connect handler address. However, connection requests are validated against the old TCP/IP address object, which still has a NULL connect handler. RESOLUTION: To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. |
