I have repeatedly experienced STOP 0x000000F7 in sr.sys "A driver has overrun a stack-based buffer" while attempting to copy a set of Internet Shortcuts to a USB drive using the XCOPY command. I infer that there is something wrong with the file name by default when shortcuts to http://www.likewise.com/index.php are added to IE Favorites. I have been able to work around the problem by simply renaming the shortcut. System is running XP SP3, AFAIK with all known production security patches. Does anyone know of a fix for this issue?
