I installed Sql Server 2005 developer edition in my system. While installing it gives the error message saying the IIS might disabled or not running in your system. If am running the iis in the browser it was working fine. Now the problem is i could not able work on the Reporting services. So, can anyone help me on this.

You need IIS up and running for SSRS 2005. For SSRS 2008 this requirement has been removed.  

If you have not found out answer already Windows Vista apart from enabling IIS there are certain steps that you need to do. Try this I used to for configuring it on my machine http://support.microsoft.com/kb/934164.. Addtionally I disabled UAC (though not recommended :( ) as I had to run IE in admin mode to look at reports

This is best one http://www.mathgv.com/sql2005docs/SQL2005ReportingServicesInstall.htm I have seen so far on web about fixing the problem.
