I have a SharePoint 2010 site that has been running for about 4.5 years now with absolutely no problems until now. It is a very basic site, mainly used for storing files. It's mostly stock - there is only one small piece of custom code.
The site worked without any issues until about a week ago when all the sudden it fails to load and displays an error:
Could not load type 'Microsoft.SharePoint.Portal.WebControls.StringResourceManager' from assembly 'Microsoft.Office.Server.Search, Version=188.8.131.52, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.
This happens immediately when hitting the root page, as well as when I try to go to the Central Admin page. I found a longer error message in the Event Viewer which I have added to the end of this post.
I'm not a SharePoint guru and I've run out of ideas on how to troubleshoot this.
So far I have tried:
- Check IIS - IIS is started, app pools are running, etc
- IIS reset
- Check Event Viewer - nothing relevant other than what I posted
- Check Windows Update - no recent updates
- Restart server
- Check 'C:\inetpub\wwwroot\wss\VirtualDirectories\80\App_GlobalResources' I do see an Office.Server.Serach resx file. (but not a DLL, is that normal?)
- Googled the error - I did not find anything yet that seems relevant. Most suggestions are regarding custom code that uses the search, and suggest fixes to that the custom code. This doesn't seem to be the case for me. Our custom code does not use Office Search, or even have a reference to that library. Also, our custom code is just a web part that is on one page (not the main page). When it breaks it doesn't take the whole system down (well, it hasn't in the past)
My questions for the community are:
- Is anyone familiar with this error?
- What else should I check?
- Should I just reinstall SharePoint and restore from a backup? (this is fine I guess... but, if possible, I'd rather know what went wrong and how to fix it.)
I appreciate your time and help.
