Solution
This error message appears because there are too
many temporary files in the 'TEMP' folder. The
IUSR_<computer name> account requires permissions
to delete files from this folder.
====================
NOTE:
By default the 'TEMP' folder is set to
'C:\WINNT\TEMP' or 'C:\WINDOWS\TEMP'. You can
designate a different folder by changing the 'TEMP'
environmental variable.
====================
To resolve this issue, complete the following steps:
1. Delete all files in the 'TEMP' folder.
2. Right-click the 'TEMP' folder, and select
'Properties'. The 'Properties' dialog box appears.
2. Click the 'Security' tab and then select the
'IUSR_<computer name> account.
3. Select the 'Allow' check box for 'Full Control'.
After deleting all the temporary files and setting
the permissions, the report now previews.
