Note this code is in http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/server/mpm/winnt/mpm_winnt.c and the only arguments that can be corrupted are the cmd we build for the child, the args to the cmd, the environment, and process attributes (program type, standard input/output handles etc). So your driver busted something; the question is, what? Since we didn't create it, you can presume we have no interest in debugging it :) But here's just a smattering of things that might help; Lingering, corrupted system environment variables? Permissions of the system account? (Try changing the service to 'Logon As' another user who you create and set up with Write permissions to the logs/ directory.) Corrupted msvcrt.dll? Corrupted service? Might have to uninstall the service, reboot, then manually delete this key; HKLM\System\CurrentControlSet\Services\[service name] and reinstall the service. > PS: this question was also asked at experts-exchange, but got little > response: So much for 'expertise' ;-) Glad you found a more informed place to ask. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
