You application is refused for Administrative processing

What does it mean ? when visa consular officer after interview told that, your wife application has be successfully submitted for Administrative processes, but your and both children administrative processing have been refused, but NO problem it will resolve in two to three days, I am keeping your all passport and she given me the paper and click on following text.

You application is refused for Administrative processing , you may be asked for additional information later, your application may be take up to 6 months to complete this process.

This simply means that they need more time to work on your application. The visa has not been denied yet. Visa officer will take a decision after verifying your documents in detail.

Dear Anil;
Thanks for your reply;
This is B1/B2 visa we applied, and they did not ask for any document to submit neither they told about " Application Refused under INA 221(g)", they just given one pink paper stated that "You application is refused for Administrative processing , you may be asked for additional information later, your application may be take up to 6 months to complete this process."

We have been visited before many time before to US
