HostnameItem converts hostname to capital letters

[xanadu]

When using HostnameItem=system.hostname the system automatically looks up the hostname from the local machine. I noticed on a windows 2003 r2 server that it converts the hostname to capital letters.
The same thing also goes for Windows Server 2008 R2. The issue would be resolved if the value is always written in miniscule.

if you lookup hostname via the hostname command it displays "server01", however the zabbix agent converts it to capitals which gives an error in the zabbix agent log:

When I manually fill out the hostname field in the zabbix_agentd.conf the error disappears:

I reported this earlier as a bug ZBX-9832. They recommended me to use "system.hostname[host]", however this doesn't resolve the problem.
