Nagios config file entries

Hello Team,

1) We have installed nagios windows server & clinet ("NSCP-0.4.1.73-x64.exe(NSclinet ++)) successfully and also we are able to connect the host using check_nrpe. present we are facing the issues with configurations, we are not able to add more host entries & services in configuration, could you please help me in adding multiple hosts and services. because of this issue we are not proceeding further.

define host{

        use                     windows-server,host-pnp            ; Name of host template to use

                     ; This host definition will inherit all variables that are defined

                     ; in (or inherited by) the linux-server host template definition.

        host_name               < >

        alias                   < >

      hostgroups             windows-servers

        address                 < >

        }

   define service{

        use generic-service

      host_name < >

      service_description CPU Status

      check_command check_nrpe!alias_cpu

      }

   define service{

        use generic-service

      host_name < >

      service_description Service Status

      check_command check_nrpe!alias_service

      }

      define host{

        use                     windows-server,host-pnp            ; Name of host template to use

                     ; This host definition will inherit all variables that are defined

                     ; in (or inherited by) the linux-server host template definition.

        host_name             < >

        alias                   < >

      hostgroups             windows-servers

        address                 < >

        }

   define service{

        use generic-service

      host_name < >

      service_description c: Free Space

      check_command check_nrpe!alias_disk

      }

 If i add one more service immediately web url is not working.
 
2) If we execute the "nagios check configuration" everty thing looks fine.

3) If we check the nagios services all 4 nagios services status is "started"
 
4) if we add Multiple host entries in confige  we are not able to see the web results then we remove one  host entry restart the nagios service we are able to see the results.  (C:\Program Files (x86)\ICW\etc\nagios\nagwin)
 
please help on configuration file entries. if you have any standard config templeat supports multiple hosts pelase share.
 
Thanks & Regards,
Naveen
