basically i am trying to automate the process for installing the device driver via command line in windows 2003 server. my driver doesn't support the command line install, i want to try installing via some utility like devcon... i want to do it thru' telnet... as thats the way my automated TCL script will do... following are the issues: 1)i am able to use devcon install from commandline, but the same thing fails when i do it from telnet session. 2)i tried looking at the devcon code and i am seeing error code 22F in updatedriverforplugandplaydevices, i left this update.... and wanted to use setupcopyoeminf file and then do a rescan to install the device, which also gives the same problem... it runs from the command line, but running it from telnet session gives a errorcode 800b0003(ERROR_GENERAL_SYNTAX) the setupcopyoeminf call is coded like the below, SetupCopyOEMInf(L"c:\\temp\\mydriver.inf",L"c:\\temp",SPOST_PATH,0,NULL,0,NULL,NULL) can someone help me out, what is wrong here? thanks a lot, /n
