Details

Troubleshoot the issue by using this guide:

Using IE browser, check if the client cannot download the server.ini using the following URLs:
- http://servername:8080/OfficeScan/download/server.ini
- https://servername:4343/OfficeScan/download/server.ini
Verify that there is no firewall between the server and the client.
Verify that OSCE server is installed on Windows 2003 server
Verify that the permissions on the IIS and folders are correct.

If it is an IIS issue, resolve it by modifying the MIME type of IIS 6.0 in OfficeScan:

Go to Administrative Tools > Internet Information Services (IIS) Manager.
Go to the download folder under OfficeScan virtual directory.
1. Right-click the server.ini file and then select Properties.
2. Under the MIME Types option, select the MIME Types button.
3. Click New.
4. Create a new MIME type with the following characteristics:
  - Extension: .*
  - MIME type: application/octet-stream.
5. Click OK.
6. Click OK to close the window.
Click Apply and then click OK to save the changes.
