Drive Information Not Support in Windows??

[aderr]

I have been fighting with this one for a while and have not been able to find any information about why I am having this issue.
I am running Zabbix 1.8.9 and trying to monitor some Windows 2003 servers.
I have not been able to get the vfs.fs.size item to return any data. I turned on the debugging log on one of the servers but I cannot see the specific parameter hitting the agent.
I can see
4960:20111230:091710.124 Requested [vfs.fs.size[d:,total]]
4960:20111230:091710.124 Sending back [ZBX_NOTSUPPORTED]

however there is no d drive on the server so that is to be expected. There is no mention of the vfs.fs.size[c:,total] key.

However on the zabbix server front end all the vfs.fs items show up as Not Supported, even after I enable them. Looking through the Latest Data for the servers, none of them have drive information. Below is the item that I am using from the windows template, please let me know if any one has any ideas on why the vfs.fs is coming back as not supported even though it should be according to the manual. (Zabbix Agent is version 1.8.9).

Type: Simple Check
Key: vfs.fs.size[c:,free]
Type of Info: Numeric (unsigned)
Data Type: Decimal
Custom Multiplier: 1

Thank you in advance for your help!
