<h2 id="description">Description</h2>
<p>Configures a connection object for use in remote computer management.<br />
This function will either create new records for computers that have no connection registered so far, or it will configure existing connections if already present.</p>
<p>As such it can be handy in making bulk-edits on connections or manually adjusting some settings.</p>

<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Get-DbaCmConnection sql2014 | Set-DbaCmConnection -ClearBadCredential -UseWindowsCredentials
</code></pre>
<p>Retrieves the already existing connection to sql2014, removes the list of not working credentials and configures it to default to the credentials of the logged on user.<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Get-DbaCmConnection | Set-DbaCmConnection -RemoveBadCredential $cred
</code></pre>
<p>Removes the credentials stored in $cred from all connections' list of &quot;known to not work&quot; credentials.<br>
Handy to update changes in privilege.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Get-DbaCmConnection | Export-Clixml .\connections.xml
PS C:\&gt; Import-Clixml .\connections.xml | Set-DbaCmConnection -ResetConfiguration
</code></pre>
<p>At first, the current cached connections are stored in an xml file. At a later time - possibly in the profile when starting the console again - those connections are imported again and applied again <br>
to the connection cache.<br>
In this example, the configuration settings will also be reset, since after re-import those will be set to explicit, rather than deriving them from the global settings.<br>
In many cases, using the default settings is desirable. For specific settings, use New-DbaCmConnection as part of the profile in order to explicitly configure a connection.<br></p>

<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
