Is it QV9 or QV10?
QVP port should be left at default value 4747.
If it's QV10 you need to change the default URL in the config.xml file, something like
If it's QV9 then just change the Port
<Port>8080</Port>BTW, you don't need both QVWS and IIS if you want to use DMS, using IIS alone should work fine.
