You cannot edit list or document library items on existing SharePoint sites

This problem was fixed in KB961175. The patch will keep the problem from happening again in new lists/libraries you create after applying the patch. However if you have a backup before the patch the restored contents will continue to show the same error. It is also true to existing items. In order to fix this other issue, Microsoft released KB971351 showing some code to fix the problem in existing items. There are two code blocks: one for webs and another for lists. At the time of this writing the codes contained some minor typos and also some memory leaks. Nothing that would prevent a developer to make it work. The memory leak is not an issue as well since it is supposed to only run once. I understand that most of the support people are not that into coding, I put together a more intuitive code together which can be downloaded here (including executable):

How do you know you are experience this problem?

The symptom is having someone with full access to a site collection, web, list or document library being unable to edit list items (user receives access denied) however user can see list items using view item.

 

Source Code:

You know the disclaimer: I work for Microsoft but the code I put in codeplex is NOT endorsed by Microsoft. This is a community tool and must be treated as such. That being told, the application complies with Microsoft best practices and can be used in your environment if you are experiencing the problems described in KB961175. The application will not change anything if you are not facing the problem described.

  For some reason I couldn't seem to get the code publised in the KB article to work when I put it into VS2010 on my x64 Server 2008 R2 environment. I know I was doing something wrong but I am new to programming c# so it was driving me insane. Running your modified pre-built application worked a treat - thank you sooooo much for this you are an absolute legend!! Thank you for spending the time to publish this and awesome work! Rich

  Just wanted to say thanks, this worked like a charm.  We got a site template from another group in our company and they are on a version of MOSS before this was fixed, so using it is what caused the issue for us.
