Crystal Reports access denied error

Hello,
I've been stumped trying to resolve the following error when running Crystal Reports on a new server I'm setting up:

HTTP 500.100 - Internal Server Error - ASP error
Internet Information Services

------------------------

Technical Information (for support personnel)

Error Type:
Seagate Crystal Reports ActiveX Designer (0x80043AC6)
Access denied.
/OrbitRpt/Crystal/AlwaysRequiredSteps.asp, line 57

I'm running a Win2K server (service pack 4) with Crystal Reports 8. I've tried setting the security to "Everyone - Full Control" on all folders but I'm still getting the "Access denied" error. Has anyone seen this before? Any info would be greatly appreciated. Thanks!The following changes fixed my problem:
To properly set up your System Environment Variables:

1. Create the directory "C:\Temp" if it is not already created.
2. Right-click on "My Computer" on the server machine, and choose "Properties".
3. Go to the "Environment" tab.
4. Under "User Variables", select "TEMP", and then click "Remove". Repeat for the variable "TMP".
5. Select any variable under "System Variables".
6. Change the value for "Variable" to "TEMP" (no quotes).
7. Change the value for "Value" to "C:\Temp" (no quotes).
8. Click "Set".
9. Change the value for "Variable" to "TMP" (no quotes).
10. Change the value for "Value" to "C:\Temp" (no quotes).
11. Click "Set".
12. Click "OK".

Be sure to give "Read" and "Delete" access to this TEMP folder so that the Crystal Reports web components can read and write to this directory.
