cmd.exe permissions

[DarkCable]

FYI to all...
If you are using IIS and have used the lock down tool,
you better make sure to check your permissions on the cmd.exe.
I have found on my server that the IUSR account had deny permissions
to the file. This stopped the server from serving images (graph files).

I think I have a permission problem somewhere...not sure.
I have the correct permissions on the cmd.exe.
When I reset (iisreset on iis5) the webserver, I can
only get a graphic once....then the page just hangs.
If I open up task manager...I see cmd.exe just hanging.
If I open up the site several more times (each in their own
browser) multilple cmd.exes appear. I cannot end them either.
It takes another iisreset command to the server...then again I
can only get one graphic to work...and then the server hangs.
For some reason, the server or php is not releasing the cmd.exe
from memory.
IIS 5.0
php 4.3.1
0.8 beta on april 1 (had same problem with 0.6x)

thanks for help in advance.

### UPDATE ###
I think the problem I am having has been isolated to only
the preview screen (where it shows a preivew of all the interfaces
I have). If I turn on graph debug...everything is ok.
In fact, I only have a problem when showing multiple graphs
on the same screen (either from same or different interfaces)
It is like IIS is getting flooded with image requests and hangs.
after it hangs, I have to do an iisreset command.



#### UPDATE ####
I found this link :

It may be what I am experiencing...

Well..I have narrowed down my problem to the php4isapi.dll file.
If I configure IIS to use only php.exe, the pictures all show up ok.
If I use the isapi filter option, I can only get one picture per page.
Any more than one cause the servers to hang...I have to do a
IISRESET command.
