Timeout executing shell script (Hyper-V Template)

Hi,

I have a problem with the Hyper-V template. Some of the items doesn't work, because shell script gives a timeout.

Example running from console:

```
zabbix_get.exe -s myhost -k hyperv.host[discover,vm_na]
ZBX_NOTSUPPORTED: Timeout while executing a shell script.
```

Can you give me any advice about this?

Thanks,
