Hi, We have some issue while accessing one of the URL (as like below with unstandard port no: 2443) from windows 7 Professional Edition with IE 8 but all other websites works fine , However we tried this link accessing from Win XP Sp3 with iE8 it works fine. https://abc.def:2443/NPRD.htm Let us know is there any setting which blocking this website accessing from Windows 7, We have tried the below option which did not helped much. - Disabled Windows Firewall - Enabled Firewall with specifying firewall policy rule Also we ran the netstat command to check the connection status on both windows 7 and windows XP systems and noticed if we access the above link from windows 7 professional computer it takes above 49000 port number (local port) to connect to website and with Windows XP Sp3 it takes between 3000 to 4000 Port number (Local Port) to connect to website. Is there any option to restrict local port number to access specific websites in Windows 7 Operating system. Thanks, Pradeep

Hi Pradeep, Did you receive any error when trying to access the website? Are those windows xp PCs within the same network environment? First, I would suggest check the IE settings first: Open Internet Options->under Security tab->click on restricted website->Site, check if the URL was list there. Second, locate the hosts file in C:\Windows\System32\drvers\etc, open it in notepad and check if any malicious record on the specific URL. If so, remove it.
