ITunes 9.2 (Error Message -50)

Question

I seldom have the need to access iTunes Store (not iPhone, iTouch, iPad user) - However recently I discovered that my iTunes 9.2 is unable to access the online store at all! This will definitely affect me in the near future if I decides to get the new iPhone4, as updates and apps are done via iTunes Store.
I kept getting the following error message every time I try to sign in to my Apple account of the iTunes Store:
+*"We could not complete your iTunes Store request. An unknown error occurred (-50). There was an error in the iTunes Store. Please try again later."*+
I have re-tried ample times, uninstalling and reinstalling iTunes, it just don't work till now. Even tried Apple's Support help "http://support.apple.com/kb/TS1811", that don't work for me either! I'm running a wireless broadband connection at home.
Any experts able to assist here? =X

Answer 1

I have a resolution to the problem! I hope it will work the same for you too!
1. Launch your iTunes as per normal.
2. Go to iTunes > Preferences > Parental. This is the area to resolve this problem!
3. Under Disable: Check the boxes for *'iTunes Store'* and *'Allow access to iTunes U'*. By doing these will disable accessibility to the 2 areas. Click OK.
4. Exit iTunes completely and relaunch iTunes again.
5. Go back to iTunes > Preferences > Parental. Now we uncheck the 2 boxes for *'iTunes Store'* and *'Allow access to iTunes U'*. This way, we are enabling the access again! Click OK to continue.
6. Now attempt to sign in your Apple ID to access your iTunes Store, it should be up and running properly! +(at least for me still...)+
