How do I create a internet proxy for an account that does not have internet access?

The development domain for my current client does not given its account internet access. Thi can be overcome in Powershell scripts as follows:

$user = "MyDomain\MyAccount"

$password = ConvertTo-SecureString –String "password" –AsPlainText -Force
$cred = New-Object –TypeName System.Management.Automation.PSCredential –ArgumentList $user, $password

[System.Net.WebRequest]::DefaultWebProxy.Credentials = $cred

but it becomes a problem is the current user credential is used do download files or if the proxy server blocks certain actions. A fantastic tool to resolve this problem is cntlm, which allows you create a local internet proxy.

The configuration (simplified) is as follows:

1. Download and install the software.
2. Set the username and domain in the .ini file. Remove the password setting
3. Type the Url of internet proxy.pac file in a browser and get proxy urls. Add these urls to the config file and remove the 'sample' entries.
4. Execute 'cntlm -M http://www.google.com' and get the authentication type. Copy the Auth and Password to the configuration file.
5. Remove/uncheck the 'Automatic configuration' settings and update the proxy in the browser to point to localhost 3128 (which is configured as the listen port)

6. Close existing browsers and restart the windows service.

You should be good to go.

SharePoint 2013: Error updating managed account credentials

I encountered the following message when trying to change a password for a managed account: Error deploying administration application pool credentials. Another deployment may be active. An object of the type Microsoft.SharePoint.Administration.SPAdminAppPoolCredentialDeploymentJobDefinition named "job-admin-apppool-change" already exists under the parent Microsoft.SharePoint.Administration.SPTimerService named "SPTimerV4".  Rename your object or delete the existing object. The error message is self explanatory - Rename your object or delete the existing object.  I choose the latter. Powershell to the rescue. $job = Get-SPTimerJob -Identity "job-admin-apppool-change" $job.Delete() Reset the password and all should be good.

Error deploying Nintex workflow: An item with the same key has already been added

My client recently upgraded their version of Nintex Workflow 2010 and suddenly some of my workflows started to fail on deployment. The following error cropped up: Error deploying workflow: Server was unable to process request. ---> An item with the same key has already been added. ---> An item with the same key has already been added. WTF???? A little digging unveiled the problem - I had two items in a 'Create Item' shape with the SAME DISPLAYNAME. I needed to move the second item to a new 'Update Item' shape in order for it to work. I order to get the workflow to deploy, I had to manually remove the 'duplicate' item from the serialized XML. Hooray!! It was then a simple matter of creating a new shape to update the 'duplicate' value.
