Description:
The description for Event ID (8214) in Source (Windows SharePoint Services 3) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: A request was made for a URL, http://novashare, which has not been configured in Alternate Access Mappings.  Some links may point to the Alternate Access URL for the default zone, http://novadc2.  Review the Alternate Access mappings for this Web application at http://nasdac
: 13651/_admin/AlternateUrlCollections.aspx and consider adding http://nasdac as a Public Alternate Access URL if it will be used frequently.  Help on this error: http://go.microsoft.com/fwlink/?LinkId=114854.

Resolution:
1.       Open you Central Administration site and go to “operations”
2.      Look for “Alternate Access Mappings”
3.      In the page you will find “Alternate Access Mapping Collection” and it will say “Show All”
4.      Click on the small arrow point downwards on this “Show All” location and you will get “Change Alternate Access Mapping Collection”
5.      Go ahead and choose the Web Application which is responsible for the problem site
6.      You will see that there is a URL already showing in “Default” zone
7.      You need to specify the URL which is giving you problem in the “Intranet” zone. So it will see like this:
Default: http://sharepointmagic
Intranet: http://myspinventions.org
8.     Performed IISRESET

Now everything should be working fine, you should be able to check-out and edit the office documents
