NRPE check_disk

Im having this strange issue atm

I use NRPE to check my other servers and its always good but I have this 1 server that outputs wrong. This is only with the disk checks… the other checks are all just fine!

example:
[root@nagiospilot libexec]# ./check_nrpe -H hostx.networkx.nl -c check_diskD -t 20
Drive D: - Total: 23 MB - Free: 21 MB - Used: 2
[root@nagiospilot libexec]# ./check_nrpe -H hostx.networkx.nl -c check_diskD -t 20
Drive D: - Total: 22.18 GB - Free: 20.35 GB - Used: 1.83

and its wrong for like 70% of the time or worse… It is a windows box 2003

is there anyone who had this issue before ?

well thanks in advance

I managed to resolve it myself.

Installing the NRPE service as a specific user on windows… I used nagios…
