I created a new service in order to monitor the free space of unit C: for windows server and attached it to different hosts. Some of them worked like a charm they look ok and send properly the status, but, on the other hand, there're a small amount that are giving error:
- (Return code of 255 is out of bounds) --> This error is returned by server with NSClient++ version 0.4.1.105
- CHECK_NRPE: Error - Could not complete SSL handshake. --> This error is returned by servers with NSClient++ Version: 0.3.9.328
I googled those errors, just for give a try solving them, but all solutions given are not working.
The hosts which are returning those errors have other services configured and working properly.
Here is the service details:

$USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c CheckDriveSize -a MaxWarnUsed=$ARG1$ MaxCritUsed=$ARG2$ Drive=$ARG3$:
All the affected hosts are Windows Server 2008 R2 x64
