Get "unknown error" when adding new users

  Asked By: Bobbi    Date: May 13    Category: Sharepoint    Views: 4070

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.

Hi, any updates to this? I am experiencing this in a site I am supporting as well.

Same issue, unknown error is thrown as soon as you click on "New" or even on the "Site Permissions" link.

I am going to adjust the custom errors/callstack in the web.config and hope that points us in the right direction.
