It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

what is the error/behavior? Did you set any name resolution (hosts file or DNS entry) that resolve the host name to the IP of the server ? – Steve B Jul 2 '12 at 11:58
I assume there is a DNS record in place for your host header pointing to the correct web server? A hosts file entry would also do for local testing. Do you get any error message? – Thomas Vochten Jul 2 '12 at 12:00

Is this SharePoint 2010 or MOSS? When you say you have a problem accessing the site - what does that mean? a 404? blank page? constant authentication? what is the issue?

You need to check in Central admin for alternate access mappings (where this is, depends on 2010 or 2007), this sets up the valid URLs your web application can be accessed on. Also double check in IIS that the host header is present on the new site.

Need more detail to diagnose this.

If you use host headers you need to check the Loopback adapter settings for your server:
