Have you run into some interesting errors or humorous Knowledge Base Articles lately? Well, I run into them once in a while. Here are a few. Sometimes in the middle of an intense troubleshooting session you deserve a little relief. Check em’ out.
The reason for this error was that the operation completed successfully
This error was on my SharePoint server.
The Windows SharePoint Services Timer service depends on the Netlogon service which failed to start because of the following error:

Authentication prompts have been a pain in the neck for a lot of SharePoint users over the years both in SharePoint 2007 and SharePoint 2010 environments. There are several reasons for the prompts. I can’t cover all the possible solutions but I have documented multiple solutions to different authentication prompt issues.
In SharePoint 2010, you have multiple site collections on your intranet that you access on a regular basis. When you access these sites remotely from an external network and connect to the first site you are prompted for authentication. You logon successfully. Then you try to connect to the second, third and fourth Site Collection but you are prompted for authentication each time. You want to have access to all the sites without being prompted for authentication each time.
Add the intranet sites to the Local intranet zone in Internet Explorer (IE).
Now once you logon to the first intranet site, you should be able to access all the other sites in different Site Collections without entering your username and password.
NOTE: There are lots of other scenarios where you may experience multiple authentication prompts and depending on the scenario you may have to use a different solution. One setting that you should be aware of is located in the Internet Explorer’s options.
NOTE: You can deploy this setting to client computers using Group Policy. Go to User Configuration -> Policies -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Trusted Sites Zone. In the right-hand pane locate “Logon options” double-click it. First Enable the option and then in the drop-down box select the option “Automatic logon with current username and password.” On the client computer run gpupdate /force at the command prompt to refresh the Group Policy.
Prompt for Credentials When Accessing FQDN Sites From a Windows Vista or Windows 7 Computer
There is another issue that you may run into that is documented in the KB article 943280. Sometimes you may get prompted for authentication when you open a Microsoft Office document in SharePoint. Here are the steps documented in the KB article 943280 to resolve the issue in Windows 7 clients.
- Click Start, type regedit in the Start Search box, and then press ENTER.
- Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
- On the Edit menu, point to New, and then click Multi-String Value.
- Type AuthForwardServerList, and then press ENTER.
- On the Edit menu, click Modify.
- In the Value data box, type the URL of the server that hosts the Web share, and then click OK.Note You can also type a list of URLs in the Value data box. Here’s a sample.
- Exit Registry Editor.
After this registry entry is created, the WebClient service will read the entry value. If the client computer tries to access a URL that matches any of the expressions in the list, the user credential will be sent successfully to authenticate the user, even if no proxy is configured.
Note You have to restart the WebClient service after you modify the registry.
Things to avoid in the URL list
- Do not add an asterisk (*) character at the end of a URL. When you do this, a security risk may result.http://*.dns.live.*
- Do not add an asterisk (*) before or after a string. When you do this, the WebClient service can send user credentials to more servers. See the following examples:
- http://*Contoso.comIn this example, the service also sends user credentials to http://extra_charactersContoso.com
- http://Contoso*.comIn this example, the service also sends user credentials to http://Contosoextra_characters.com
- In the URL list, do not type the UNC name of a host. For example, do not use the following:*.contoso.com@SSL
- In the URL list, do not include the share name or the port number to be used. For example, do not use the following:
- Do not use IPv6 in the URL list.
Important This URL list does not affect the security zone settings. This URL list is used only for the specific purpose of forwarding the credentials to WebDAV servers. The list should be created as restrictively as possible to avoid any security issues. Also, because there is no specific deny list, the credentials are forwarded to all the servers that match this list.
NOTE: You can deploy the above setting to clients using Group Policy.
Disabling Authentication Prompts in SharePoint 2010
In SharePoint 2010, another thing you can try to disable authentication prompts is to modify the Web.config file.
<add verb=”OPTIONS” allowed=”false” />
<add verb=”PROPFIND” allowed=”false” />
Disable “Remember my credentials” Option
If the users check the option “Remember my credentials” and then they change their password, they will keep getting prompted for authentication. It is not a good idea to remember passwords for security reasons and when working with SharePoint you might want to disable this feature. You can disable this feature using a Group Policy. Open the Group Policy (e.g. Default Domain Policy) and go to Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options and enable the setting “Network access: Do not allow storage of passwords and credentials for network authentication.”
Use Credential Manager in Windows 7
Yet another method to avoid authentication prompt is to use Windows 7′s Credential Manager. Go to Control Panel -> User Accounts and in the upper left hand corner select Manage your credentials.
Select Add a Windows credential and provide the logon information.
There is no need to reboot the computer. You should be able to access the site in your browser without being prompted for logon credentials.

A lot of blogs and articles on the Internet indicate that in order to crawl PDF documents in SharePoint Foundation 2010 you must install Microsoft Search Server. I want to clear this myth by stating that according to Microsoft, Search Server is not required to crawl PDF files in SharePoint Foundation 2010.
The main problem that people run into is the fact that, unlike WSS 3.0, SharePoint Foundation 2010 does not have an interface to add file extensions for additional file types and iFilters. So how can you crawl additional file types, such as PDFs, in SharePoint Foundation 2010? One easy solution is to use the following VB script. The VB script is available in the KB article 2518465. Here’s the step-by-step procedure.
if WScript.Arguments.Count < 1 then
extension = wscript.arguments(0)
Set gadmin = WScript.CreateObject(“SPSearch4.GatherMgr.1″, “”)
For Each application in gadmin.GatherApplications
For Each project in application.GatherProjects
Note that this method adds the PDF extension. You can use the same technique to add additional filters as necessary.
If you go to Google or Bank of America’s Web site you will notice that your browser displays a custom logo to the left of the URL. It’s nice to have a custom icon or logo for a SharePoint 2010 site so when visitors add the site to their Favorites in Internet Explorer or Bookmarks in Mozilla Firefox it displays the custom icon/logo. I wrote about this last year but in this blog I have added numerous troubleshooting tips that will come handy. You can follow the procedure described below to change the browser icon for a SharePoint 2010 site.
There may be other methods of achieving this but this is the method that I use. The procedure is very simple but it requires you to use SharePoint Designer 2010. The good news is that SharePoint Designer 2010 is a free download from Microsoft. The bad news is that if you don’t know what you are doing you can completely destroy your site by “messing” with your site in SharePoint Designer.
WARNING! Always backup your site before you make any modifications to your site in SharePoint Designer 2010.
NOTE: If you are working with a standard HTML-based Web site (not a SharePoint site) then all you have to do is copy the favicon.ico file to the root of the Web site, e.g. wwwroot folder, and your icon will be displayed automatically. The root folder is where your home or index file is located. There is no need to edit any files.
If your icon is not displaying properly, here are some troubleshooting tips.
Have you ever experienced the following error in SharePoint Server 2010 when you try to open a Microsoft Word 2010 file? I have run across this error a few times on Windows Server 2008 R2 computer running SharePoint Server 2010 and Office 2010.
Word experienced an error trying to open the file.
Try these suggestions.
* Check the file permissions for the document or drive.
* Make sure there is sufficient free memory and disk space.
* Open the file with the Text Recovery converter.
Here’s a solution that has worked for me.
You may also experience this error in other Microsoft Office 2010 applications. Just use the same method to disable Protected View.
