After running February 2016’s batch of Microsoft security updates, we started receiving calls from end users about errors when attempting to update their passwords through the Citrix web interface.

Thankfully it didn’t take long for some savvy Citrix support forums users to pinpoint the issue to a recent patch Microsoft released which changes the api behavior for NetUserChangePassword.
