Subdomain Problems

[marquis.soft]

Hi

I migrated from Ensim and started using Plesk a month ago. I have a problem accessing any subdomains created. They are accessible for a day or so and then not. If I delete the subdomain and recreate it, it is accessible again - but only for a day or so again.

Does anyone know why this happens?

Thanks.

what exact error message do yoju see when you try to see your subdomain?

In Firefox I get the message 'Server not found'

In IE7 I get the message 'Internet Explorer cannot display the webpage'
