Hi, I am fairly new to using windows server 2008, but an encountering a peculiar problem. I have a samsung multifunctional, standalone connected to the network. Windows server has detected it and installed it as default printer. I have also installed the samsung universal scan driver and windows server detects it fine. Furthermore, to get the wia service, I installed the desktop experience feature on windows server 2008. Now, if I try to import a picture from scanner in paint, it nicely starts the windows scan program and all works perfectly fine. If I start a different application, a small business app for keeping records and I try to scan, 99 out of 100 times, it use a different,samsung made driver and program which doesn't work. On the odd occasion it does work, it uses the (wia?) windows driver and program and scans just fine. For some reason, I can't tell windows server to only use wia? Or uninstall the non wia drivers? Can anyone help me? Especially the 99 times no go, 1 in 100 times work fine bit is just doing my head in... Regards, Ramses
