Hi all, This seems like a stupid question but here goes : In the lab I have setup a windows server 2003 inc exchange, and two workstations, at the time I used an old 24 port 10 meg switch and all works fine, yesterday I got hold of a new 8 port 100 switch and no matter how I try I cannot get them to communicate, even by pinging they cant see each other, so I assumed the 8 port to be faulty, today I purchased a new 8 port switch and still the network does not work. I have now tested both 8 port hubs on another test network and both switches work fine ........ scratching my head now, how come both switches work on another network but not the domain controlled win2003 server test network ???????? anone shd a light on this for me Steve Alcock Calder House Spring Lane Colne Lancs BB8 9BD www.calderglen.net phone : +44 (0) 1282 871717
