<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Execute" preCondition="integratedMode,runtimeVersionv4.0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Execute" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Execute" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
</handlers>

Answer 1

Try removing the webdav module manually from GUI of IIS.
1) Goto the iis.
2) Goto the respective site.
3) Open "Handler Mappings"
4) Select WebDav. Right click on it and delete it.
Note: this will also update your web.config of the web app.
