I have 20 computers (XP-P)along with a 1TB network HD connected using WORKGROUPS (no internet connection). All machines, network HD, and router/switcher are 1Gb. The best I can do speed wise is 25% or about 130Mb/sec. All the machines show a yellow triange with ! on the network connection on the task bar - I assumed this was due to the lack of a internet connection - but could something else be wrong? The LaCie network HD is advertised to allow 25 connections.
