My problem is more or less getting the credtool to work, does anyone know the proper syntax I should use to get this to work with a 3rd Party Application. If I can't get this to work with this app, what is the alternative? Can I map a higher port using IIS, if so what would be the syntax for using IIS on that higher port? I am using Serv-U FTP, and I have read over the learning zone notes. These notes describe in some detail how to make the high port work. I am using the new version of Serv-U and have run into a few problems using the credtool.exe. When trying to use the credtool.exe with the proper service which is now Serv-U and not Serv-u32. I checked for the service name on the server and its name is Serv-U, so i assume after researching that this will be the bracketed name in the wspcfg.ini file. WSPCFG FILE [Serv-U] ServerBindTcpPorts=21 (Want this to be high port 421) LocalBindTcpPorts=20 (Should this be port 420) Persistent=1 KillOldSession=1 ForceCredentials=1 The firewall client is installed correctly and working as well. After getting the correct information in the .ini file I try using Credtool and get errors every single time. When I type in credtool -r -n c:\progra~1\Serv-U\ServUDaemon which is the executable that starts the program, i get this error ERROR: Authentication data were not found for [c:\progra~1\Serv-U\ServUDaemon] Am i missing something with the configuration of the .ini file or the credtool.exe.....does anyone have any idea where i should go next so i can this high port running.
