apache 2.2.10 can't use VirtualHost with SSL

[Buddy wu <ejournal4me@xxxxxxxxx>]

my environment is windows server 2003 and apache 2.2.10

if I use VirtualHost director in httpd.conf without SSL support, Apache can startup and servering request.

but when I enable SSL,like use "SSLEngine on" directive, and enable Virtual host together , apache can't startup, it saids " The requested operation has failed" and don't give any other messages or errors.  the syntax is ok， can pass the test configration process. 

and if the httpd.conf don't has VirtualHost part, it can startup with SSL opertion, and through https to access the site. 

what's wrong. can anybody help? 

thanks
