LMHOSTS

LMHOSTS is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand LMHOSTS rather than just read about it. In short: The LMHOSTS (LAN Manager Hosts) file is used to enable Domain Name Resolution under Windows when other methods, such as WINS, fail. It is used in conjunction with workgroups and domains.

Key takeaways

LMHOSTS belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect LMHOSTS to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of LMHOSTS from memory before moving on to harder problems.

Reference excerpt

The LMHOSTS (LAN Manager Hosts) file is used to enable Domain Name Resolution under Windows when other methods, such as WINS, fail. It is used in conjunction with workgroups and domains. If you are looking for a simple, general mechanism for the local specification of IP addresses for specific hostnames (server names), use the HOSTS file, not the LMHOSTS file. The file, if it exists, is read as the LMHOSTS setting file. A sample file (lmhosts.sam) is provided. It contains documentation for manually configuring the file.

File locations Windows 95, 98, Millennium Edition

The file is located in %windir%, and a sample file (lmhosts.sam) is installed here. Note that %windir% is an environment variable pointing to the Windows installation directory, usually C:\Windows. Windows NT 4.0, Windows 2000, Windows XP, Vista, 7, 8, 10, Windows Server 2003, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2016+

The file is located in %windir%\system32\drivers\etc\, and a sample file (lmhosts.sam) is installed here. Note that %windir% is an environment variable pointing to the Windows installation directory, usually C:\Windows.

Worked examples

Example 1 — a first encounter with LMHOSTS

Start with the simplest possible case. Write down what LMHOSTS claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to LMHOSTS before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about LMHOSTS ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of LMHOSTS

In research: LMHOSTS appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses LMHOSTS in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: LMHOSTS is common in secondary-school and first-year university syllabi. It links to neighbouring topics Configuration files, Windows communication and services, so understanding it makes those chapters shorter.
In everyday life: Look for LMHOSTS outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is LMHOSTS in simple terms?

The LMHOSTS (LAN Manager Hosts) file is used to enable Domain Name Resolution under Windows when other methods, such as WINS, fail. It is used in conjunction with workgroups and domains.

Why does LMHOSTS matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study LMHOSTS?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on LMHOSTS.
