Hi I am running preupgradecheck command on sharepoint 2003 in windows 2003. It is giving me error that is : " Missing operation name or the operation name is invalid" . The path of stsadm command is as under : " C:\Program Files:\Common File\Microsoft Shared\Web Server Extensions\60\Bin> STSADM.EXE -o preupgradecheck" I would like to know where is the problem or this command doesn't run in Sharepoint 2003. If this command doesn't run on the sharePoint 2003 then how to check the compatibility of the server for Sharepoint 2010. Pls reply soon Rgds Puneet SudPuneet Sud
