We are hosting the DNN site in a webfarm environment using the UNC shared approach.  Everything works fine except for the skin installation part.  When attempting to install skin package, after the skin package was parsed, we got this error "A critical error has occurred. Could not find a part of the path 'c:\stgnas001\data\cms\phoenix\Install\Temp\hs3dx3dw\phoenix_skin.dnn'."

The installation process is trying to access the path under c drive which is not where the site files are hosted.  Is there anyway to get around this?
