Turn off XP unknown publisher warnings

Yet another thing that drives me nuts about XP. I'm sick of having to tell the system over and over that I actually DO want to run the program that I just executed. This will prevent that dialog box from popping up every time you try to run a new file on the system.

Run gpedit.msc, and go to
Local Computer Policy
 ->User Configuration
  ->Administrative Templates
   ->Windows Components
    ->Attachment Manager
Enable "Default risk level for file attachments"
Enable "Inclusion list for low risk file types"
Add the file extensions that you want to open without being bothered.

.exe; .zip; .rar; .doc; .xls; .com; .bat; .lnk; .msi;
note: right click on Administrative Templates and add system.adm if if attachment manager is not showing.

     logon hangs does not show resources...SCHFH issue

When you logon to Windows by using cached logon information, if the domain controller is unavailable to validate your account, you cannot access network resources that require domain validation. However, you can access network resources that do not require domain validation.

How to reset your Serial Number in Windows XP
example:  > xp is looping with activation request and will not logon
               > boot in safe mode/command prompt
               > run regedit | search for oobetimer
               > change/delete data and reboot
               > attempt activation and/or call Microsoft
Run regedit and go to: HKey_Local_Machine\Software\Microsoft\WindowsNT\Current Version\WPAEvents
on the right double click on "OOBEtimer" and change at least one digit of this value to deactivate windows.

2. Choose run from start menu and type in this command:
%systemroot%\system32\oobe\msoobe.exe /a
to get the activation screen and go to the second option which is activate by phone.

3. In the new screen choose the option to change product key, and type in the new product key (Corporate one only).

4. Close that window, reboot your system and enter the command in step 2 for the second time to verify your activation , you should see "windows is already activated".

To restrict null session connections (or disable null session access):
  1. Start Registry Editor.
  2. Locate, and then click the following key in the registry:
  3. On the Edit menu, click Add Value, and then add the following registry value:
    Value Name: RestrictAnonymous
    Data Type: REG_DWORD
    Value: 2
    Default: 0
    A value of 2 restricts null session connections.

    To set the RestrictAnonymous value, change the registry key to 0 or 1 for Windows NT 4.0 or to 0, 1, or 2 for Windows 2000. These numbers correspond to the following settings:
    • 0 None. Rely on default permissions.
    • 1 Do not allow enumeration of SAM accounts and names.
    • 2 No access without explicit anonymous permissions
  4. Restart the computer.

Method 2

Use the following method to avoid null session connections that have a high session idle time and that have opened a handle to the named pipe \PIPE\spoolss.
