I have NSClient++ installed on a VMware virtual machine. The virtual machine has Windows Server 2003 on it. Nagios is able to pull over all the normal stats(memory, drive space, CPU, etc.) but its showing explorer.exe as 'Not Running'. The NSClient was installed on the virtual machine with the local administrator account in hopes that it would fix the explorer.exe problem...but it didn't. So my last thought is that Nagios is having trouble recognizing explorer.exe because its a virtual machine. Has anyone encountered this problem?
Side Note: I have Nagios monitoring a Windows Server 2003 machine but NSClient is installed natively(the server isn't a virtual machine). This was what led me to believe that the native vs virtual instances of the OS is causing the problem.
