Try backing up and rebuilding the Apache configuration, then restarting Apache:
Code:
# cd /usr/local/apache/conf
# cp httpd.conf httpd.conf.pre-rebuild.bak
# /scripts/rebuildhttpdconf
# /usr/local/apache/bin/apachectl configtest
# /scripts/restartsrv_httpd
Also, check to make sure that the subdomains resolve to the correct IP address. When you say "they were not accessible," do you mean that you saw an error in the browser, or the Apache default page, or something else?
If the subdomains resolve to the correct IP address, and rebuilding the httpd.conf file does not help, please submit a ticket so that we may log into your server and investigate the problem directly.
