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:

  1. Go to Administrative Tools > Internet Information Services (IIS) Manager.
  2. 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.
  3. Click Apply and then click OK to save the changes.
