Practice & Litmus Tests Ezine #29 - Registry Hacks for Internet
This weeks ezine tackles virus attacks on your Internet Explorer.
My main emphasis is on using Regedit to solve annoying problems in the
registry. These are my 3 objectives for this ezine.
- Understanding how a virus could attacks your Internet Explorer
- Awareness of your registry settings.
- Experience of .Reg files.
Calculating IP Address
ranges is a black art, which many network managers solve by creating custom
Excel spreadsheets. IPAT cracks this problem of allocating IP addresses
in networks in two ways:
For Mr Organized there is a nifty subnet
calculator, you enter the network address and the subnet mask, then IPAT
works out the usable addresses and their ranges.
For Mr Lazy IPAT
discovers and then displays the IP addresses of existing computers.

Scenario: Your homepage is locked in Internet Explorer.
The problem is that your Internet Explorer's menus have been locked. You can no longer set
the home page, or worse, you cannot open the Tools (Menu) Internet Options..

be affected sooner or later.

The problem "HomePage"
When you try and change Home page Address, unfortunately, 'Use Current' is greyed
If you experience this IE problem at your office, then it is

your network administrator has a group policy in operation; if so, the chances are
that their group policy will also forbid registry changes.
Where there are no group policies in effect, then I would suspect a Virus attack, those menu's do not just 'Grey out' of their own accord.
Open Regedit and navigate to 'HomePage" by tracing this path:
Note: this is a job for HKEY_Current_User (not HKLM).
Just to be clear, 1 = lock, "HomePage"=dword:00000001
Whereas, 0 (zero) = unlock "HomePage"=dword:00000000
In my opinion, the only use of "HomePage"=dword:00000001 is for
testing the problem.
You may know that you can make changes to the registry by double clicking or
merging .reg files. These are .reg files ordinary text files with the path and
keyword(s) necessary to change the registry without blundering about with with regedit.

Internet Explorer Tools (Menu) lockout
The situation is this, in Internet Explorer, you wish to alter the Internet Options
however, all that you get is an error message saying :
This operation has been cancelled due to restrictions in effect on this
If you are at work, then perhaps your Administrator really has a group
policy which stops you changing your options. In that case, the chances are that the group policy will also
forbid registry changes.
Alternatively, if you are at home the problem may be due to Microsoft
Plus! for Kids 1.0.
However, in my case I believe it was a virus, for example TABER
Again you need to make a registry change. One way of finding
the right place in the registry would be to the Edit (Menu), Find : NoBrowserOptions
This "NoBrowserOptions" option is controlled by a different section of the registry.
Note the word \Policies
Once again the logic is 1 = Locked, 0 = unlocked.
