Cant access the iTunes server config page

[JOT]

Hi all;
I recently purchased a QNAP TS-119P II and would like to enable the iTunes server. I enabled iTunes server from the Administration page and also checked the "After enabling..." checkbox and hit Apply. I then clicked the link just below the "After enabling..." line (suffixed by port ":3689") but Safari shows the page as not found. I am running the latest version of firmware (per the QNAP website, 3.6.0 Build 0210T). Can anyone help?
Thanks
