It's regarding Powershell which I feel is a language that's more used by sys admins than developers, hence being here rather than stackoverflow.
It's regarding manipulating server configuration, which firmly places it here
Given that only just over 15% of powershell questions on serverfault have yet to be answered, I'm now wondering if perhaps there's information lacking from my question that would help others to answer it. Being new to Powershell and far from an expert in IIS configuration (other than via the GUI) I'm not sure what more I could add.
If my question would be better placed on stackoverflow (due to the quasi-coding nature of it) or needs more detail (because I'm a muppet), I'd appreciate any feedback either way =)
I think your question is fine -- It's possible nobody has an answer (posting a question does not guarantee an answer - it just means people will see it).
Also your question is only a day old, and has only been viewed a few times. Give people a chance to actually read it and determine if they know of any solutions. A lot of our PowerShell gurus don't come to the site every day, so patience is a virtue (or so everyone keeps telling me anyway) :-)
