U have problem with internet ports , or maybe ur firewall block's ur itunes connection .
Check c:\windows\system32\drivers\etc\hosts to see if there are activated more ip than

127.0.0.1 localhost
#74.208.10.249 gs.apple.com
#127.0.0.1 gs.apple.com


Should look like this .

Thanks for answer I did that now it shows error 21 while update to 5.0.1

done updated thanks for help.
