Have a Windows XP SP3 on a Windows 2003SBS network. This user ONLY has the issue of when they click on a network mapped folder that has some "size" to it meaning many subfolders and GB's worth of data the response is slow. If she clicks on a network mapped drive folder that is smaller in nature and not many subfolders the response is normal/fast. What settings could be tweaked to allow the speed to increase when she clicks on these folders that are large in Data Size and has many subfolders. I have other XP users in the office that are NOT experiencing this issue -- only this 1 PC.
