I cannot scan to an HTTP or 
HTTPS site.
1. If the machine has been configured to scan to an HTTPS 
destination with Server Validation enabled, the scan will fail if 
the server certificate is either expired, untrusted, or contains an 
incorrect domain name. Verify the HTTPS configuration within 
CentreWare Internet Services.
2. Verify the server certificate within CentreWare Internet 
Services.
3. If jobs greater than 2MB are failing using the ASP script, the 
server upload limit may need to be increased. 
• Open the service manager and temporarily stop any IIS 
related services. 
• Edit the file MetaBase.xml on the server. The file may be 
located using the Windows search functionality. 
• Locate the AspMaxRequestEntityAllowed variable and 
make its value larger. 
• Restart the IIS service.
4. If jobs greater than 2MB are failing using the PHP script, the 
server upload limit may need to be increased. 
• Open the phh.ini file. 
• Adjust the following settings to accommodate the desired 
upload limit for Network Scanning or Server Fax jobs: 
upload_max_filesize, default_socket_timeout, 
max_execution_time, max_input_time, memory_limit.
5. To help determine possible failure reasons: 
a) Refer to the Server Log which may reside in the following 
locations: IIS - c:\windows\system32\LogFiles\W3SVC1 or 
for Apache - /apache/logs/. 
b) Look for errors in script operations identified in the log, such 
as directory permissions denied, size limits exceeded, etc.
