With reference to previous problem, not really any further forward.
I set up a W2K Pro system to act as a Wingate server with nothing else on it. Tested it in my workshop uploading & downloading from my client's website server and it worked with no problems.
Put the server in place at my client's - everything working except for FTP which will now allow small files <2K to upload to his web server from his workstation, but fails on anything bigger (the same problem from another workstation). Works fine connecting to my server from the same client systems.
He can FTP to his web server from his system using dial-up so the problem must be network/Wingate related.
Please, please, can anyone suggest what could possibly be wrong with either his network or Wingate? Where should I look for a clue?
Thanks
Jackie
