In sharepoint 2007 I have tried to access the lists.asmx service(http://sppcd2/_vti_bin/Lists.asmx) in the browser. But I am getting an access denied error. I am site collection admin of the web application but still I am getting the Access Deined error.I have checked in the regedit - DisableLoopBackCheckup is available.

I have commented the following line in the http handler section of the web.config of the web application.
<remove verb="*" path="*.asmx" />

After Commenting the above mentioned line I am able to access the lists.asmx service and it's working fine. This will affect any issue in the working behaviour of the web app could anyone provide why the lists.asmx is working after commenting the line <remove verb="*" path="*.asmx" /> in the http handler section.
I have commented this line(<remove verb="*" path="*.asmx" />) in the http handler section and due to that it will affect the behaviour of the web application ? The service is working now (http://sppcd2/_vti_bin/Lists.asmx).
