Cannot see graphics. RRD files not updating.

Hi Cacti community!

I'm trying to monitor some servers running Windows Server 2008 R2 with Cacti.
I installed Cacti on a Windows Server 2008 R2 with your setup for Windows (http://forums.cacti.net/viewtopic.php?f=3&t=14946) with all features but can not get data from the "devices".

Once installed cacti I try to add new devices. These are in fact recognized in the page of the device can read SNMP information received from it.
I am going to create graphs: "Host MIB - Logged in Users" and "Host MIB - Processes" and wait for the poller be invoked at least a couple of times, then I go to see graphs.
I get an empty graph:


I check the logfile. I get no errors:

If I export a graph to CSV i can see all data is NaN.
RRD files are created with success, but they are not updated, since the last update date is the same as the creation date.
I've tried to monitor processes with Procmon but there is no ACCESS_DENIED.

Can you help me?

hurray, finally a user who tries to solve problems themselves and posts useful information!

You're clearly getting valid SNMP data, so the problem must lay with rrdtool and/or user permissions. Did you ever run poller.php manually with an administrator account? As a test, change the Cacti task to run as the SYSTEM account. If the rrds then start to get updated, there is a permission problem somewhere.

If you change the cacti logging level to debug, it'll show you the rrdtool update commands and possibly any errors thrown too.

I had the same problem.
After a day searching I saw that rrdtool did not have network access.
It turned out that under the file properties all the files in the rrdtool folder where blocked because they came from another computer.
After Unblocking the graphs started updating.
