Hello All, I've problem with my ispconfig box. We can see website correctly and then they are unreachable and then it's OK and then it's not ok, etc, etc .... It's only on website who are in subdomain (example : *.e4y.org / *.espace4you.org and *.espace4you.com) For example, I can't access on site1.e4y.org ==> firefox's error : "Server unreachable", but I can access on site2.e4y.org, etc ... The problem is very random. I don't know if it's become to my Bind server or others. Could you help me please ? Thank you for your answers.
