[Dxbase] DX Clusters/Hosts files

[JNMazzoni]

 I am a new user trying to set up the sytem to allow me to access DX clusters. Here 
 is the situation......
  
 * In the Internet tab the IP Hosts window has one listing/ message   " Could not 
 open PKTCMDS.TXT"
 
 * In my system (Widow 98) there are eight (8) Hosts files as listed below . Each one contains many 
> other files. 

        Hosts.sam
        LMHosts.sam
        Hosts.001
        Hosts.002
        LMHosts.002
        Hosts.dxb25.bak
        Hosts.dxb25.bak ..........recent

 When I look directly at the DX base host file it seems to contain the same files as the ones I have listed above, e.g. excel, explorer, MS Access, MS Backup etc. etc. I couldn't tell what to copy to paste to one of my Hosts files and which of my Hosts file to use. 

Can anyone help?
