Hi,
When publishing one project within Win 2012 server, I've got this
Error 1 Web deployment task failed. (There was an error reading IIS configuration schema from 'C:\Windows\system32\inets
rv\config\
schema\'.)
0 0 Start
Why? Please see the screenshot attached for what I do to publish it.

Also check the permissions on the schema folder
It is also said to be a known issue when using WS2012 with Windows 8 and IIS 8
