Specifig Graphics Not showing up

[pamram]

Windows 2000 Adv Server
IIS 5
cacti-0.8.6c + cactid as the poller
MySQL 4.1.8
php-5.0.3
net-snmp-5.2.1 + gnu_regex.dll in %windir%\system32
rrdtool-1.0.48 for win32 (1.0.49 is unstable under windows)

Some graphics show ok, some show with no info and some doesn't show at all (error box).

For example, on a Cisco 3725, the device setup screen shows:

1) Cisco - CPU Usage Is Being Graphed (Edit)
2) Interface - Errors/Discards Not Being Graphed
3) Interface - Traffic (bits/sec) Not Being Graphed
4) Interface - Unicast Packets Not Being Graphed
5) Linux - Memory Usage Is Being Graphed (Edit)
6) Unix - Ping Latency Not Being Graphed

On this one, the #1 and #5 show up but without info, the others doesn't even show up. I'm also monitoring the server where cacti is running, and only 4 graphs show ok, the rest are either blank or not showing up (error box with an X).

Any bright ideas anybody? I appreciate the help. One last thing, is the windows job for the poller.php. dependent on the cmd.exe? Those cmd windows are really annoying !! Thank you !

PS: I'm attaching a copy of the cacti log file.
