If you are using Excel Calculation Web Part on your SharePoint site you might get the following error:
“Excel Web Access. An error has occured. Please contact your system administrator if the problem persists.”
if you are using Kerberos authentication, then this might be the issue. Try to access your site using NTLM authentication and if it worked the you know that it is Authentication issue caused by Kerberos which most probably is not correctly configured in your environment.
Solution:
Make sure that the SPNs are registered correctly specially for the NLB since most of the time it is forgotten!!! and follow this article to configure Kerberos correctly: http://technet.microsoft.com/en-us/library/cc263449.aspx
