Adding Links to TopNavigation via Powershell

Question

I am receiving the following error when attempting to add a Link to the Top Navigation Bar.

"Exception calling "AddAsLast" with "1" argument(s): "Access is denied"

Here is the code:

$web = Get-SPWeb $url.Url;

$newLink = New-Object Microsoft.SharePoint.Navigation.SPNavigationNode -ArgumentList  @($web.Title, $web.Url);  

$web.Navigation.TopNavigationBar.AddAsLast($newLink);
$web.Update();

looking for some reasons and work arounds. Thanks!

Answer 1

The syntax is fine, I run the exact same code and it works without a problem.

Some things to look at:

• Does your account have the right level of access? I know, probably silly question, but just checking
• What does the ULS log say when you're running this command?
• Try wrapping in an SPSecurity.RunWithElevatedPrivileges({}) statement
• Try some more simple cases (get the web then update it immediately without adding anything to the navigation bar to verify navigation is part of the problem)
