Sounds like the 'Connections' tab has been disabled by a policy.
1) Close all Internet Explorer windows.
2) Launch the 'Group Policy Editor' by entering 'Gpedit.msc' in the Start menu's 'Run' dialog.
3) Navigate to 'User Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Disable the Connections page'.
4) If the value shows 'Enabled', right-click on this policy, click on 'Properties' and change the option to 'Not configured'. Apply the change, click OK then close the 'Group Policy Editor'.
Re-run Internet Explorer.
Alternatively, you can edit the Registry, i.e. to re-show the 'Connections' tab, paste the following into Notepad and save as 'show-connections.reg':
Code:
REGEDIT4
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Control Panel]
"ConnectionsTab"=dword:00000000
Double-click on the saved 'show-connections.reg', merge it into the Registry then re-run Internet Explorer.
Finally, to remove policy restrictions that prevent the display of all 'Options' tabs in Internet Explorer, paste the following into Notepad and save as 'ie-options-allow.reg':
Code:
REGEDIT4
[-HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Control Panel]
Double-click on the saved 'ie-options-allow.reg', merge it into the Registry then re-run Internet Explorer.
Hope this helps...
