What Is a Server Address?

The Open Systems Interconnect (OSI) model for network communications establishes a layered approach to communicating between computers on a network. Each layer of this seven-layer model may have its own way of referring to the other computers with which it communicates. This means that any given network server may have many different addresses on file--for use with the different communications layers at work. Ethernet Working at layer two of the OSI model, all systems connected to an ethernet network will have a unique ethernet address. This address is expressed as a set of eight hexadecimal values, such as 00-2B-78-5F-03-8A. This address may be used by network switches and bridges to help constrain and route traffic to this particular server. Internet Protocol The Internet Protocol, working at layer three of the OSI model, establishes a unique IP address for every machine on the Internet. IP addresses have three parts: network address, node address and subnet mask. Though the o...

Troubleshooting NTLM

This section provides help for diagnosing and resolving any issues that might arise when configuring NTLM.Alfresco supports NTLM v2 protocol, which is more secure than NTLM v1 protocol. However, NTLM v2 cannot be used with pass-through authentication. You will have to switch to NTLM v1 if you want to use pass-through authentication, where Alfresco passes the log on request to an Active Directory or other server to validate the login credentials. roubleshooting This problem is most likely caused by enhanced security in Windows 7, Vista and Windows 2008. Previous versions of Windows (XP) would fall back to NTLM v1, if NTLM v2 failed. On Windows 7 clients, navigate to Control Panel > Administrative Tools > Local Security Policy. In the left pane, navigate to Security Settings > Local Policies > Security Options. In the right pane, find Network Security: LAN Manager authentication level. By default, the value of Network Security: LAN Manager authentication level is ...

How Can I Lower an Upstream Power Level?

Upstream power levels that are too high will affect a modem connection's consistency. As the levels increase, the modem's ability to connect to the provider decreases, which may cause the modem to power down or disconnect. As with all modulation signals, the upstream power level tends to fluctuate depending on various influences including temperature and signal interference. If the problem is on your end, it may be due to poor cabling, bad connections or a faulty splitter. Troubleshoot your upstream power levels by first capturing the initial results and then begin going through the procedures necessary to identify the problem. Step 1 Connect your computer directly to the modem, using an Ethernet cable. Open a Web browser and type your router's IP address in the address bar, such as "192.168.0.1." This accesses the modem's software interface. Step 2 Click the "Status," "Signal" or "Statistics" link. The names can vary by ma...

Disabling Storage of the LM Password Hash

You want to prevent the LM hash for new passwords from being stored in Active Directory. The LM hash is susceptible to brute force attacks and is primarily used for backward compatibility with Windows 95 and 98 clients. Solution For Windows 2000, you need to create the following Registry key on all domain controllers: HKLM\SYSTEM\CurrentControlSet\Control\Lsa\NoLMHash. Note that this is a key and not a value entry. Also, this is only supported on W2K SP2 and later domain controllers. For Windows Server 2003, the NoLMHash key has turned into a DWORD value entry under the HKLM\SYSTEM\CurrentControlSet\Control\Lsa key. This value should be set to 1. You can accomplish this by modifying the Default Domain Controller Security Policy as described next. Using a graphical user interface 1.Open the Group Policy Object Editor and target the Default Domain Controller Security Policy. 2.In the left pane, expand Local Policies → Security Options. 3.In the right pane, double-click on Ne...

How to Validate Windows

Microsoft protects its software copyrights with validation codes and product keys. One way they do this is through a program called "Windows Genuine Advantage." This program requires that you validate your copy of Windows to make sure it is "genuine" before you can access the "advantages" of the Microsoft website. When you purchased your Windows software, you were supplied a product key that is necessary for Windows to install. Validation simply checks that product key against Microsoft's database to ensure your copy of Window has not been pirated. Windows Validation Step 1 Go to the Windows validation website (See Resources). Step 2 Click "Validate" in the menu bar beneath the page title "Genuine Microsoft Software." Microsoft download websites typically support Internet Explorer, but if you are using Mozilla Firefox, you will be redirected to a download page that is compatible with your browser. Step 3 Click the "V...
