Hello, I may be having network problems but I'm not sure. When the transfer gets to 2.254 gigs the transfer fails showing many send errors then finally says, always at 2.254 gigs "send error". I am on a 100 megabit network using computers with 10/100 realtech 8139s. The updcast software brings up 2 nic modules and the one that works is called ...8139too. Some 10 megabit devices are also running on it. The cd is very easy to use using the default setting. I tested the udpcast software at home on a fully 100 mega bit network and everything just worked fine. I guess (or hope that) the problem must be with our old network at school that has many old devices hanging on it or old and bad wiring. How should I use the --half-duplex option and would this help? Also, I tried an older crossover cable and it only ran at 30 megabit or so and also failed going directly from machine to machine at the 2.254 gig mark. It showed the same errors the busy network transfer. It worked at home, so it must work at school... Thanks for any ideas, Jim _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail
