I have a network with about twenty-five nodes. All the machines are Windows 98 boxes except two which have Windows 2000. When exploring network drives on the two Windows 2000 boxes, windows explorer stops responding for a couple of minuets and then begins responding agian until another file or directory is accessed then explorer stops responding again for a few minutes. This makes for very slow browsing and is very annoying. Does anyone know if this is a Windows 2000 problem or network. Oh, by the way the network is NT4, BackOffice Server. This doesn't occur on the 98 boxes. Any Ideas?
