With each passing version of Windows, it seems that it wants to build previews of files and it ends up going slower. You can de-registrer the DLL that builds such a preview to see if that's it. You should also look at the usual XP networking speed tweaks. ->

I have a network with 20 Windows 2000 clients, a couple of Windows98 clients, and a couple of Windows NT 4 computers. Recently I had to add a couple of computers and these ended up being Windows XP Professional SP2 machines.
The problem I am having is with some applications that open scanned documents (TIF files) across the network. A 20 page image will open up with the first page displayed and about 7 subsequent pages shown as thumbnails. On the Windows 2000, 98, and NT machines this happens in about one second. On the Windows XP machine it takes one second per thumbnail. These XP machines all have AMD 3400+ and higher CPUs with 512MB to 1GB RAM. The Windows 2000 machines range from 500Mhz to 750Mhz and have 128MB or less.
I have tried the browsing/scheduler related fix, but that has made no change at all. I have turned off the firewall, installed NetBeui, turned off every service possible, but it still takes much longer to do the same thing the "slower" 2000, NT, 98 machines are currently doing.
Does anyone have any ideas?
One thing that may be of significance is that the Windows Imaging control used in the software does open and close the image file for each thumbnail in a multi-page tif, which seems a bit odd to me, but it still works fine on the other operating systems.
