I am not sure where to start here so I will go with the most obvious, what type of QVS license do you currently have (user cals, session cals, etc). Next the urls you give above are not the same as each other, if i am to assume this is not a mistype you might want to try the working url but replace the localhost with the ip address, of course this is only assuming you did not type what you meant above as webfolder & webfolder.htm are two completely different things 🙂 .
Btw I have seen a similar issue before and it turned out to be a licensing issue see this forum:
