Sharepoint 3.0 SP-2

Hi,

we are trying to install the FIM 2010 R2 on SharePoint 3.0 SP-2. SharePoint is installed successfully. However, when we open the  file applicationHost.config  to add (” As per the  FIM 2010 R2 test guide lab, there should be ” added.  Two of the instances will have
useKernelMode=”false” already present. so total are  5 - windowsAuthentication enabled=”true”.But in our environment, there are only 3 -windowsAuthentication enabled=”true” . Please help us to resolve the issue. It seems due to this, FIM portal is not successfully installed. FIM Installation is   roll backing automatically.

Thanks

Anil
