Windows XP slow opening TIF files over a network

by DMan65 / November 17, 2006 1:08 AM PST

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.

Hello Bob,

Thanks for the reply. Unfortunately this isn't a problem associated with browsing. The user never even opens a file system dialog box. They put a document number into a text field and the software determines what file server has that document number and opens that file. So there is no browsing associated with the process. I had already deactivated the scheduling query and now I have tried the other link you mentioned, but the problem persists.

The computer isn't having any trouble in finding the file. I have watched the SMB packets go back and forth and I am not seeing any errors, but it takes far longer for XP to do this than it does Windows 2000. I am guessing I will have to try to find some older computers that have Windows 2000 and just replace these newer machines with those.

I found transfers to go faster after these tweaks.

I take it you are not open to trying them to get them out of the way?

I don't have this issue, but I know that all my drivers are current and the firewall isn't looking over each packet, got plenty of ram, cpu and whatnot.

Light bulbs you shouldn't buy

There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
