Security settings
In order to be able to access a Microsoft Windows 2003 server with a panel or PC you must disable the following security settings on the Microsoft Windows 2003 server.

Under "Start > Programs > Administrative Tools > Security Policy for Domain Controller > Security Settings > Local Policies > Security Options" you locate the security settings. 

Applicability
The settings described are to be made only

• If you are using a Microsoft Windows 2003 server with Active Directory.
• If the Windows CE 3.0 operating system is installed on the operator panel.
  Operator panels with the Windows CE 5.0 operating system are not affected
  (e.g. operator panels MP 277 / Mobile Panel 277 and higher). You can check which operating system is being used on the operator panel in the Control Panel under "System > General".

Disabling security settings:

• Microsoft network (server): Digitally sign communications (always).
• Microsoft network (server): Digitally sign communications (if client agrees).
• Network security: "LAN Manager authentication level" change to "Send LM & NTLM responses".

After you have made the settings you must reboot the computer. This makes the changes made effective.

Note:
The changes made lower the security level of the network communications. Please check beforehand with your network administrator whether you are permitted to make these changes.
