My colleague has configured new SharePoint site 2013, to replace the old one which was SharePoint 3.0, he has put the DNS entry for new SharePoint site, but on home page its not viewable.
The old share point site can only be accessed when I restart the server on which it was hosted, and it keeps dropping down after 1 or 2 hours.
So how can I make the new sharepoint site to appear on home page?
How I can fix the issue with old sharepoint site which keeps on dropping? ( Staff need to still access it to review and migrate there content)
