that the driverlist could not be rebuild ("driver files possibly corrupted - access denied"). Nevertheless the new driver is functional and uploaded correctly. After removing the Win9x driver from the box, the next upload does not result in an error message any more. This behaviour does not occur using Win2k as print server (Xp->Win2k) nore when transmitting drivers from a Win2k client to my box. Hope, anyone has an idea. Thanks, Martin
