In our companies network we have a folder that contains a large amount of files. This folder is on a windows NT server. It contains over 50,000 files taking up about 11 gb of space. There are a couple of subfolders. When ever someone in our network browses to this folder, it takes about 30-45 seconds for the folder to actually open and display the files. However anyone in our network that has an NIC integrated into their motherboard with VIA Rhyne Ethernet Adapter is able to open and browse the folder instantly. No one with a PCI NIC can and no one with any other integrated NIC's are able to instantly open the folder. Everyone has 100mb adapters and the OS vary from windows 2000 and XP. We can't figure out why the Rhyne NICs are able to open the folder so quick but the others are not. Since we know it is possible to open them quickly, is there anything we can do to speed up the others? They browse fine to all the other folders in the network..
