While most corporate organizations in Malaysia have implemented intranet or portal, questions regarding users' utilization behavior for the purpose of knowledge sharing still remain unanswered. Against this concern, this study seeks to investigate demographic profiles associated with knowledge sharing behavior in an intranet computing environment in selected Malaysian companies. Using the survey research method, 700 questionnaires were distributed using the simple random sampling technique yielding to 359 usable responses. The findings suggest that there is a significant difference in terms of knowledge sharing behavior across demographic profiles. In addition, it was also found that both length of service and internet experience is a significant predictor of knowledge sharing behavior in an intranet computing environment.
