Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – doncherry Jan 15 '13 at 6:45
isn't it called mdframded? – Rico Jan 15 '13 at 9:22
@Timebandit mdframed ;-) – Harish Kumar Jan 15 '13 at 9:32
@Harish Kumar my bad, it's to early ;-) i'll edit the question maybe we find someone to answer this question afterwards – Rico Jan 15 '13 at 9:35
@Timebandit I doubt that this question gets some answers in its current form :-) – Harish Kumar Jan 15 '13 at 9:51

Assuming that you are using the fancyhdr to make the header, simply redefine \headrule to do nothing:
\renewcommand\headrule{}
