Error Description
** Last updated on December 6, 2002 **                          
NOTE:  The latest modifications are marked with a "*" in the    
first column.  The changes made on December 6, 2002 were only  
to the format and not the content.                              
This information is for all releases of Client Access          
Express for Windows, now called "iSeries Access for Windows"    
in V5R2.                                                        
The following servers are used by Client Access Express for    
Windows.  In addition to the servers listed, the Port Mapper    
(Port 449) is also used by all functions.  However, if the      
user changes the Connection properties for an iSeries connection
so that "Where to look up Remote Port" is set to "Standard" or  
"Local," then the Port Mapper will not be used.  In addition,  
if a DNS server is to be accessed, Port 53 should be made      
available to the client.                                        
NOTE:  The port number in parentheses is the one used to        
 connect to the server via SSL (encrypted session).            
 See more notes after the following list of servers.

        STRHOSTSVR *ALL command.  The others need to be started
        individually, or can be set to autostart when TCP/IP is
        started (as can 449, 8xxx, and 9xxx).                  
Note 2: Although 8474 is listed next to NetServer, it is only  
        used internally so does not have to be set in your      
        firewall IP filtering.  However, that server (print    
        server) must be started for NetServer to work properly.
Note 3: If any applications are registered under Application    
        Administration, then the remote command server will be  
        required in addition to what is listed below.          
Note 4: Port 5544 is required only on V5R1 and later systems    
        and is used for both non-SSL and SSL traffic.          
        Port 5577 is only required for SSL connections          
        between the "central" system and "endpoint" systems.
