Windows 2003 is increasingly favored by users for its stable performance, but in the face of endless new viruses, you still need to strengthen the security of Windows 2003.
1. User Password Settings
Setting a password for a key can largely avoid password attacks. The character length of the password setting should be more than 8 characters, preferably a combination of letters, numbers, and special characters, such as "psp53, @pq", "skdfksadf10@", etc., which can effectively prevent brute force cracking. It is best not to use your own birthday, mobile number, phone number, etc. as a password.
2. Delete the default share
Click "Start → Run", enter "gpedit.msc" and press Enter to open the Group Policy Editor. Expand User Configuration→Windows Settings→Scripts (Login/Logout), double-click the login item, and then add “delshare.bat” (parameters do not need to be added) to delete the Windows 2003 default share.

Then in the window shown in the figure, the remotely accessible registry path and sub-path content are all deleted. Four strokes to enhance Windows 2003 security
