Okay, looking at the last script snippet posted by Grasshopper75 in http://www.kixtart.org/board/ultimatebb.php?ubb=get_topic;f=2;t=004433 it does seem to write to the NICs, however, it writes empty values. You will have to substitute the empty values with the relevant values of your own network. Multiple WINS entries can be inserted by using the pipe character as described in the KiXtart Manual under WRITEVALUE().

Also, please read Why does the console display zeros and ones (amongst others)? in the FAQ Forum.

The CheckNICs() UDF might fit your bill, too.
