Sharon,

Here is a sample message: 
Authorized Use Only! 

You must be assigned an account to access this computer and the network.
The information on this computer and network is the property 
of this organization and is protected by intellectual property rights. 
Anyone using this system expressly consents to their activities being monitored. 

The Graphical Identification and Authentication (GINA) at login that is displayed can be interpreted as 
an invitation to breach system security. The "Welcome" caption on the dialog box cannot be changed. 
However, you can enable a warning message dialog box to be displayed. 

NOTE: This dialog box is presented to the user after they press CTRL+ALT+DEL and before the logon dialog 
box is presented. 

Windows NT and Later
To enable a warning message to be displayed, make the following changes to the registry: 
Start Registry Editor.
From the HKEY_LOCAL_MACHINE subtree, go to the following subkey:
SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon 
Add or modify the following values:
      Name                 Data Type   Value
                -----------------------------------------------
                LegalNoticeCaption   REG_SZ      Dialog Caption
                LegalNoticeText      REG_SZ      Dialog Message


Windows 95 and Windows 98
To enable a warning message, modify the following registry key: 
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Winlogon 
The string values will appear on the logon banner.

Example: 
"LegalNoticeCaption"="Important Notice:"
"LegalNoticeText"="No Unauthorized access allowed"

Hello List,

We have a small network consisting of an NT 4.0 Server with Win95, Win98
and W2k workstations connected to it. There are three versions of a
login banner popping up on these workstations and we need to standardize
to the one "official" version. We've changed the banner on the server,
but this has only changed some workstations. Most still have their old
login banner displaying. Can anyone tell me how can we push out the
changed login banner to all workstations?

I've been doing mainframe (acf2/racf) security for 10 years and just
started working on our NT environment (didn't lose the MF resonsibility,
though), so I apologize if this question is overly simplistic. Please be
kind.
