The legacy systems only support smb version 1.0 but I can work around it though. To be honest, I wasn't sure if this was just another one of those things as the technology gap increases between old retro PCs and newer PCs. I must confess that a lot (most actually) of the technical aspects where way over my head, but finding that it wasn't just an oddity at my end I thought I'd better report it and see what others think. I understand that to properly fix the problem it will take a lot of time, especially for an old unsupported protocol, and for my simple needs I can easily work around it. Thank you for your time. Ian.
