WinInet was developed for use by Internet Explorer. In fact, to use later versions of WinInet, you must load a minimal installation of Internet Explorer. WinInet also exposes APIs for use by other client applications that wish to access resources on the Internet or intranet. It is important to recognize the environment in which WinInet was developed and tested in order to understand the appropriate use for the DLL.
WinInet was developed for use in a client environment. The preferred solution is to use WinHttp, which is designed to run in a service environment, and because it is a server-side HTTP stack, it is not bound to the two connection limit that is imposed by RFC that client-side HTTP stacks.
Another problem to be aware of when using WinInet in a server environment is the two-connection limit imposed by Internet Explorer. While is possible to use WinInet in a service and in a server environment, it is not recommended nor is it supported by Microsoft. Please rate your experience Yes No. Any additional feedback?

These utilities allow a user to store many account passwords in one central location, locked with a master password. If you know the master password, you gain access to your entire list of passwords.
But before allowing users to save passwords in such tools, consider the risks: first, it is software-based and therefore can itself become a target of attack, and, second, since it is all based on a single master password, that password becomes a single point of failure for all the user's passwords.
The best technique is to combine technology, physical security, and company policy. Sometimes passwords need to be documented. You should discourage writing down passwords in many situations, but if writing them down helps or is necessary, be smart about it. Although most users do not realize it, both Windows and Windows XP allow spaces in passwords. In fact, if you can view a character in Windows, you can use that character in a password.
Therefore, spaces are perfectly valid password characters. However, due to how some applications trim spaces, it is often best not to begin or end your password with a space. Spaces can actually make it easier for users to come up with more complex passwords. A space is used between words therefore using spaces may encourage users to use more than one word in their passwords.
An interesting fact I recently discovered in my research is that spaces do not fall into any of the categories for Windows password complexity requirements.
It is not a number or letter yet does not count as a symbol either. So while it will make your password more complex, it does nothing to help you pass Windows complexity requirements. And finally, one drawback with spaces is that the spacebar makes a unique noise when tapped. It is not hard to hear when someone uses a space in their password.
So use spaces, but don't overuse spaces. In Windows and XP it is implemented through the "Passwords must meet complexity requirements" policy. While it is often a good policy to enforce, some users may find it frustrating when their passwords are rejected because they are not complex enough.
Even experienced administrators have likely had to enter multiple passwords before finally getting one that does pass complexity requirements. Frustrated users certainly are not going to be giving you or your password policy much support.
If you find users are frustrated with the complexity requirements, perhaps a better solution is to not enforce that policy but instead require long passwords. If you do the math you will see that a nine-character lower-case password is roughly as complex as a seven-character password that uses upper and lower-case letters and numbers.
The only difference is how the password cracking software handles different character subsets; some brute-force password crackers may attempt all lower-case letters before trying numbers. Educating users on what makes a password complex and giving them some ideas for strong passwords will also help. Although they are useful in some situations, you should also consider the disadvantages. First of all, holding down the ALT key and typing on the numeric keypad is something that can easily be observed by others.
Second, creating such a character requires five keystrokes that must be memorized and later typed every time the password is entered. Perhaps a more effective technique would be to make your password five characters longer, which would actually make your password much stronger for the same number of keystrokes. For example, a five-character password made up of high-ASCII characters will require 25 keystrokes to complete.
Clearly, you are better off just making longer passwords. Another thing to consider is that some laptop keyboards make numeric keypad input difficult and some command-line tools may not accept high-ASCII characters. Nevertheless there are times where it is good advice to use extended characters codes. If you have sensitive service or local admin accounts that are rarely used, sometimes the extended character set will be worth the extra keystrokes. Since few password crackers are set up to handle extended characters, that may be enough to make your password very difficult to crack.
But in that case, don't stop with high-ASCII, one little-known fact is that you can actually make use of the full Unicode character set which has 65, possible characters. This character appears as a space and can often fool those who are somehow able to view the password. Say, for example, that an attacker is able to install a keylogger on your system.
If you use a non-breaking space in your password, it will look like a regular space in the keylogger's logfile.
But if the attacker is not aware of the non-breaking space, and without seeing the actual ASCII code, the password they think they have will fail. And many people simply are not aware that this character exists, although perhaps they do now. Office Office Exchange Server. Not an IT pro? Resources for IT Professionals.
