You may need to go through these steps on the client to make sure it is allowing access to WMI

is there any way to monitor a windows server without installing any agent....

WMI should be pre-installed, but some systems may have security context that blocks access remotely.

Without using an actual agent, or WMI, or SNMP, You would only be able to check if certain ports on the machine were accessible. Nagios is awesome, but it still needs a way to get the data, and for security sake this is a good thing, if there was a way for it to access all of your system information without you specifically allowing it, this would be available to any intruder...

the nagios server we use is a linux server...how do i check if wmi is already installed on my xi server

If you have a 2012 version of XI, it is pre installed on the XI server

we are on 2012R1.0.....

It should be installed on the XI server, you can verify by running the following command the document I linked earlier was more about page 2-12 setting up the windows machines to make sure they allow connections...
