           Refer to the IM Security Getting Started Guide for 
           messaging clients and recommended system requirements.


5. Installation
========================================================================
   This section explains key steps for installing the software. Refer to 
   the Getting Started Guide for detailed information such as 
   deployment considerations and pre-installation tasks.
 
   1) Setup automatically installs RTC Client API 2.1 and MSDE 2000 
      IM Security instance.
      
      Note: Setup skips this step if you are upgrading from previous 
            IM Security build or if you have not removed these programs
            from previous IM Security installation.

   2) Set the product and database installation folder.

   3) Configure the Web server and proxy server settings.

   4) Activate the product and set World Virus Tracking participation.

   5) Set administrator and notification accounts.

 
6. Post-Installation Configuration
========================================================================
   Trend Micro recommends performing the following tasks after installing
   IM Security:
   
   - Prepare other antivirus applications running on the IM Security
     server by excluding IM Security's quarantine, backup, and temp
     directories.
     
     For example, if you have Trend Micro(TM) ServerProtect(TM) running,
     exclude the IM Security archive, backup, download, and quarantine
     directories from its real-time, manual, or scheduled scanning.
     Refer to your server-based antivirus product's documentation for 
     instructions on how to configure the exclusion list.
   
   - Verify successful installation by testing EICAR through a file
     transfer session.
     
   - Update components manually to ensure the latest antivirus and
     content protection.
     
   Note: The Getting Started Guide has the complete post-installation
         instructions.


7. Known Issues
========================================================================
   Here are the known issues in this release:

   1)  Files being transferred are not scanned if IM Security services
       are stopped.       
   =====================================================================
       If IM Security services are stopped when the sender is initiating
       a file transfer session to intended recipient(s), file is not
       scanned and will be delivered to intended recipients. Such file
       may harbor viruses or other threats, which can result to a virus
       outbreak.
       
       Restart the IM Security server or its services during holidays or
       off-peak hours to avoid this scenario.

   2)  IM Security performance counters are missing from the 
       Performance Monitor > Object list.
   =====================================================================
       When using a Remote Desktop Protocol (RDP)-based client to 
       remotely manage an IM Security server, the performance counters
       for the product are missing.

   3)  The "Cancel instant message transfer" action prevents archiving 
       of messages to the LCS Archiving Server.
   =====================================================================
       If Cancel transfer is selected for instant messages matching a
       content filter rule, IM Security will not deliver the message to
       intended recipient. Consequently, this action prevents the message
       from being archived to the LCS Archive Server.

   4)  Removing the IM Security MSDE 2000 instance before the IM Security
       program prevents the latter from being uninstalled successfully.
   =====================================================================
       Do not uninstall MSDE 2000 nor RTC API Client 2.1 if IM Security
       is still installed. Uninstalling IM Security will automatically
       remove these programs.

   5)  IM Security does not support Access Proxy server and other LCS
       server roles.
   =====================================================================
       IM Security can only be installed on LCS 2003 Home server and 
       LCS 2005 Standard or Enterprise Edition (Front-end). Other LCS
       server roles are not currently supported. Please refer to the
       Getting Started Guide for detailed system requirements.
   
   6)  Unwanted keywords are still delivered to intended recipients.
   =====================================================================
       If a message or file matches two or more content filtering rules,
       IM Security will apply the action set by the rule with the 
       highest priority. If the rule with the highest priority set 
       the Deliver action, unwanted keywords will still be delivered 
       to intended recipients.
       
       Trend Micro recommends giving higher priority to rules with the
       most restrictive action (for example, Replace entire content).

   7)  Notifications or files cleaned by IM Security cannot be delivered.
   =====================================================================
       IM Security uses the agent notification account (IMS_<server name>)
       to send notifications and cleaned files. If the account is blocked
       in Windows Messenger, IM Security will not be able to send 
       notifications or cleaned files to intended recipients.
       
       To prevent this issue from happening, do not block the IM Security
       agent notification account from Windows Messenger.
       
   8)  PDF/HTML reports issues
   =====================================================================
       8.1) PDF reports cannot be opened nor read.  
             
            If the following settings are enabled, PDF reports cannot be
            displayed. 
       
            - HTTPS management console through Secure Sockets Layer (SSL)
            - Internet Explorer > Options > Advanced > "Do not save 
              encrypted pages to disk"
            
            As a workaround, disable “Do not save encrypted pages to disk”.

       8.2) HTML reports cannot be open directly when sent as email
            attachments.
            
            If the "Internet Explorer Enhanced Security Configuration"
            Windows component is installed, reports sent as email 
            attachments cannot be opened directly from the email.
            
            As a workaround, uninstall “Internet Explorer Enhanced 
            Security Configuration” or save the attached *.MHT file to a
            folder on your computer before opening the report.            

   9)  Certain files are blocked even if IM Security file blocking rules
       are disabled.
   =====================================================================
       By default, Windows Messenger 5.1 blocks the following file 
       extensions:
       
       ade, adp, app, asp, bas, bat, cer, chm, cmd, com, cp, crt, csh, 
       exe, fxp, hlp, hta, inf, ins, isp, its, js, jse, ksh, lnk, mad, 
       maf, mag, mam, maq, mar, mas, mat, mau, mav, maw, mda, mdb, mde, 
       mdt, mdw, mdz, msc, msi, msp, mst, ops, pcd, pif, prf, prg, pst, 
       reg, scf, scr, sct, shb, shs, tmp, ur, vb, vbe, vbs, vsd, vsmacros, 
       vss, vst, vsw, ws, wsc, wsf, wsh
       
       Please refer to the Windows Messenger documentation for more
       information.

   10) Live Communications Server Snap-in generates an error when trying
       to stop or restart LCS service.
   =====================================================================
       In a Live Communications Server 2003 deployment, starting, 
       restarting, or stopping the LCS service through the LCS Snap-in 
       generates the following errors:
       
            'Live Communications Server Snap-in failed to start one or 
             more dependent services. For more information see Event 
             Viewer...'
            
            'Live Communications Server Snap-in failed to stop one or
             more dependent services. For more information see Event
             Viewer...'
       
       These errors do not prevent IM Security services from starting
       or stopping. Click OK, and then try starting, restarting, or
       stopping the LCS service. The error message no longer appears.
       
       Start, restart, or stop the LCS service through the Windows 
       Services panel to prevent this issue from happening.
    
   11) Some help content cannot be displayed when using Netscape 
       Navigator.
   =====================================================================
       The IM Security main online help and context-sensitive help are
       using JavaScript codes. Some JavaScript codes are not compatible
       with Netscape Navigator. This situation prevents the help content
       from being displayed and generates an error similar to the 
       following:
 
            'arrayofDivs has no properties'
       
       This issue does not happen when using Internet Explorer.
