Problem:
Following the use of the Microsoft IISLockdown security utility, the ArTrac G4 Real-Time Performance Plug-In no longer displays thumbnails or charts. Instead, an "X" appears in the upper left corner of where the image would appear.
Solution:
The problem is that the lockdown tool denies write access to all IIS directories. The Real-Time Performance plugin generates thumbnails and charts dynamically and must write the images to the NevronTemp directory under the wwwroot path. To fix this use the following procedure:
For Windows NT Server and 2000 Server:
1. In the ArTrac G4 machine, give the ASPNET group write permission for the entire directory:
- C:\InetPub\wwwroot\NevronTemp
2. Open up the task manager in the ArTrac G4 machine and click on the "Processes" tab.
3. Locate the process named aspnet_wp.exe and end the process. It will automatically restart in a few seconds.
4. Access your ArTrac G4 system and attempt to display a Real-Time Performance thumbnail or chart again. You should note that the screen now displays correctly.
For Windows 2003 Server:
1. In the ArTrac G4 machine, give the NETWORK SERVICES group write permission for the entire directory:
- C:\InetPub\wwwroot\NevronTemp
2. Open up the task manager in the ArTrac G4 machine and click on the "Processes" tab.
3. Locate the process named w3wp.exe and end the process. It will automatically restart the next time ArTrac is accessed.
4. Access your ArTrac G4 system and attempt to display a Real-Time Performance thumbnail or chart again. You should note that the screen now displays correctly.
