Error 18 in module 244

Hello, In event Viewer of NT 4 with NF server 2.6B I have an error 18 in module 244 (e:\NF2.60A\Source\lde\server\SERVER.C (373)) module 244, is TCP/IP, but I don’t find what is error 18, can you help me?

This message means, that the server is not responding anymore. First you should check the content of your services file (at server and client computers). If you use more than one server, perhaps there is an error using the tcp/ip ports on each client. If this error occurs only sometimes, you should check the components of your network. Michael
