At our company, we’ve elected to offer Roger Zander’s Client Center for ConfigMgr 2012 utility to the staff who need to support CM12 clients. Since often that staff is roaming, instead of deploying the MSI version or instructing them to use the Click-once version, we’ve elected to offer the Browser based version.
With the latest update to Client Center, we’ve obtained a licensee key. For the Browser-based version, to avoid a prompt about whether or not to “Run” the web page, that means that you need to sign a couple of the files offered with a code-signing certificate so it is trusted within your company.
I know just enough about IIS in order to support ConfigMgr, so there was a bit of a learning curve for me to understand how to accomplish that signing. I’ve posted ‘what worked for me’ on the documentation page for ClientCenter, if you happen to use the browser based version, you might find that document helpful.
