i can't access Any buttons in CONECTIONS OF INTERNET EXPLORER.
ALL BUTTONS ARE SEMITRANSPARENT.

What is the Operating System & Service Pack?

What is the connection?

All buttons are greyed out? Including Setup...?

Hi Jephree.
Windows Xp Professional With Midia Center. A Thing Is Sp2.
The Conection Is Dial-up.
And Yes All The Buttons Including Setup Are Greyed It Out.
Thank You.

There is a security setting in the registry that will enable/disable the connections tabs.

It is reported here although I cannot confirm it on my machine:

User Key: [HKEY_CURRENT_USER\Software\Policies\Microsoft\Inte rnet Explorer\Control Panel]
System Key: [HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Int ernet Explorer\Control Panel]
Data Type: REG_DWORD (DWORD Value)
Value Data: (0 = disable restriction, 1 = enable restriction)

Perhaps this may help (assuming that this is the issue).

it doesn't work. no changes.

Have you rebooted since changing the registry? This is often necessary to create the changes invoked.
