We have an ASP.NET application that builds a query based on user
criteria/choices. We are experiencing a problem on our server, when we submit
a query that takes a short amount of time, the query works, if the query
takes over 5 minutes to perform, the query fails and we get a logon for the
server on the screen. We have tried the web page locally and it works for any
query. We do the same queries with the application on the server, and the
long queries fail.

The error in the security web log on the server is;
Logon Failure:
    Reason:        An error occurred during logon
    User Name:
    Domain:
    Logon Type:    3

I think because the query is taking so long, that a timestamp in kerberos is
getting out of range so the security portion is denied and the query fails.

How do we solve this?
