The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

MOSS 2007 - HTTP 500 - An unexpected error has occurred

Asked by vmurray in MOSS-Sharepoint

Tags: , , , ,

We have been running MOSS 2007/SQL 2005 for 6 months.  We had an issue yesterday where a user could not see all document libraries in a particular site.  We discovered that these document libraries were created to not inherit permission from the parent.  After changing this document library to copy and inherit permissions, several things happened.  I will outline the architecture.

https://servername (No known symptoms)
https://servername/subwebx (No known symptoms)
https://servername/subweb1 (HTTP 500 Internal Server Error)
https://servername/subweb1/subweb2 (Page loads, but left nav does not load - Error below)
https://servername/subweb1/subweb2/subweb3 (No known symptoms)

https://servername/subweb1/subweb2 is the site that had the document library that was changed to inherit permissions.  After this completed, https://servername/subweb1/subweb2 gets an error at the top of the left nav bar (Error below).  Other than that, the page loads.

A second side effect is that https://servername/subweb1 no longer loads at all.  You cannot access any part of it... even manually.  You get a HTTP 500 error when trying to access.

https://servername/subweb1/subweb2/subweb3 is fine.

Specific Error Message in left nav (quick launch):
An error occurred while rendering navigation for requested URL:
/subsite1/subsite2/default.aspx. Exception message: Object reference not set to an instance of an object. Stack trace: at Microsoft.Sharepoint.Publishing.Navigation.PortalSiteMapNode.GetNavigationChildren(NodeTypes includedHiddenTypes) at Microsoft.Sharepoint.Publishing.Navigation.PortalSiteMapProvider.GetChildNodes(PortalSiteMapNode node, NodeTypes includedHiddenTypes)

All other non specific errors are:
HTTP 500 internal server error
Unknown error occurred
Cannot perform this action.  Please try again later.

I have found some others having this issue:
http://www.msdner.com/dev-archive/204/328-1200-2047691.shtm

There does not appear to be a solution.  I found another article on Experts Exchange saying that someone had contacted Microsoft and recieved a download link to a KB Hotfix.  Wasn't extremely helpful, but I have a call in with Microsoft.

It sounds like a bug, but with these non-specific error messages, its hard to tell.  All help is appreciated!  Thanks.
