Problem with dual pane tree view and IIS6/Win2003

[slowtrance]

EDIT: Though I thought I looked through the other posts, now I see one mentioning the same problem. It referenced a PHP timeout setting as fixing the issue so I will try to look for that. If anybody knows for sure what to change please let me know. Thanks!

ORIG:
I have run into a problem upgrading our cacti setup. I have had it running on a windows XP box with IIS 5 with no problems (cacti 0.8.6c). I recently tried upgrading to a windows 2003 server system and IIS 6. Now I can not get the dual pane tree graph to display. It gives me the error:

"CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers."

If I use preview, list, or single pane tree view it works fine. I did not know where to look since the error is in only one specific view. I was wondering if there was something with the way the pane was generated that the new OS didn't like? The PHP, MySQL, and Cacti versions are identical on the 2003 box to the old XP box.

The specifics:
Windows 2003 Server (Std)
IIS 6
PHP 4.3.10
MySQL 4.0.22
Cacti 0.8.6c

In my include/config.php file I have
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "127.0.0.1";
$database_username = "cactiuser";

Any help would be greatly appreciated!!!

Hope this helps. If you solve, let me know. I am not certain that it is just a timeout.
