Get "unknown error" when adding new users

Asked By: Bobbi Allison Date: May 13, 2009 Category: Sharepoint Views: 677

This is very strange and has us stumped. We have a web application and we need
to add a new user to some of the sites but we all get "unknown error" message
when we click on the 'New' button to add a new user in the 'People and Groups'
section of a team site. This is an intranet server and everyone is in Active
Directory. Both Site Collection Administrators and one staff member with Full
Control get the same error message.

Is the error thrown immediately after you click "New", or does it happen
when you try to submit the form with your new users?

Does the Windows Application Log show any relevant errors or warnings?

Is the web app built in house or 3rd party? And what is it supposed to do?

Are you using the External Collaboration Toolkit for SharePoint solution
as your Extranet?

The unknown error message is a generic custom error page that comes up for a
variety of problems. The key is finding the specific error message.

* Have you checked the log files and the event log to see if there are
any specific errors?

* Have you modified the Log and Trace settings under diagnostic logging
in Central Admin to show more detail in the Trace logs for Administration and
Site Management.

* You can also change two settings in the Web.config file to display the
specific exception instead of the custom error. Change CallStack= to True and
CustomErrors= to Off. (The settings are case sensitive). Then try your action
again. You will get the specific exception being thrown and a stack dump.
