The following is required if you need OS2, Windows 95 or NT 4 SP3 or
earlier, access to resources in a Windows 2003 domain - I have used a dos
client and it does work also.
To prevent domain controllers from requiring secure channel signing or
encryption
Open Active Directory Users and Computers.
In the console tree, right-click Domain Controllers, click Properties, and
then click the Group Policy tab.
Click Default Domain Controllers Policy, and then click Edit.
Under Security Options, right-click Domain member: Digitally encrypt or sign
secure channel data (always), click Properties, and then click Disabled.
Where?
Computer Configuration
Windows Settings
Security Settings
Local Policies
Security Options
By disabling this security setting, you expose secure channel
communications to man-in-the-middle attacks.
