I know the topic isn't to descriptive but here goes... basically the network is Server 2008 - quad core, 4gb ram, dual Seagate cuda's in RAID1 on onboard controller, enough to run server 08 quickly 10 workstations all vista business - e8400's, 2gb ram, sata 3.0 hdd's all latest drivers, bios, etc in case people have questions if things were up to date. Now to the problem, we run a health care program that has the server side program and basically thin client programs that read/write back and forth to the server from the workstations. When we were on SBS 2003 and XP machines, the clients would read/write back and forth to the server almost instantly (which is what youd expect), since the upgrade to "faster" computers and gigabit LAN there is a good 10-20sec lag in accessing different pages within the program. Acessing the program on the server itself is basically isntant, connecting remotely to the server is also very quick. The only other problem is file transfer speeds.... if i drag and drop a file from the server to my workstation I am getting approx. 1-2MB tops. Any ideas?
