So here's my first request. Now that i've proven i'm now all talk and have started the network guide i need to finish i can prove it. I need someone to help me compile a list of all (or atleast the most common) cmd prompt commands (in windows) for network such as ping and tracert. All help will be appreciated.

NetDiag Syntax

The command-line syntax for NetDiag is as follows:

netdiag [[/q|/v|/debug][/l][/domainName][/fix][/dcaccountenum]

[/test:TestName|/skip:TestName]]

No switches or syntax need to be specified, but several are available, primarily to increase or decrease the level of detail in NetDiag reports. These switches are shown in the Table 31.22.

Table 31.22 NetDiag Switches
SwitchNameFunction

/q


Quiet output


Lists only tests that return errors.

/v


Verbose output


Lists more detail from test data as tests are performed.

/debug


Most verbose output


Lists the most detail from of test data with reasons for success or failure.

/l


Log output


Stores output in NetDiag.log, in the current folder.

/domainName


Find DC


Finds a domain controller in the specified domain.

/fix


Fix DNS problems


Only applies to domain controllers.

/DCAccountEnum


Domain Controller Account Enumeration


Enumerates domain controller computer accounts.

/test:


Perform single test


Runs only the specified test.

/skip:


Skip one test


Skips the specified test.

TestName


Test name


Test specified. For a complete list, see Table 31.23.

/?


Help


Displays this list.

NetDiag prints the string [FATAL] when it detects a condition that needs to be fixed immediately. The string [WARNING] signals a failure condition that does not require immediate attention.

NetDiag Tests

Run NetDiag whenever a computer is having network problems. The tool tries to diagnose the problem and can even flag problem areas for closer inspection.

NetDiag examines DLL files, output from other tools, and the system registry to find potential problem spots. It checks which network services or functions are enabled and then runs the network configuration tests listed in Table 31.23, in the order presented.

note-icon

Note

If the computer is not running one of the network troubleshooting tools listed in Table 31.23, that test is skipped and no results are displayed, not even an acknowledgement that the test was skipped.

Table 31.23 NetDiag Tests
Test Name FunctionDetails

NDIS


Network Adapter Status


Lists the network adapter configuration details, including the adapter name, configuration, media, globally unique identifier (GUID), and statistics. If this test shows an unresponsive network adapter, the remaining tests are aborted.

IPConfig


IP Configuration


Provides most of the TCP/IP information normally obtained from carrying out the ipconfig /all command, pings the DHCP and WINS servers, and checks that the default gateway is on the same subnet as the local computer's IP address.

Member


Domain Membership


Confirms details of the primary domain, including computer role, domain name, domain GUID. Checks that NetLogon service is started, adds the primary domain to the domain list, and queries the primary domain security identifier (SID).

NetBTTransports


Transports Test


Lists NetBT transports managed by the redirector. Prints error information if no NetBT transports are found.

Autonet


Autonet Address


Checks whether any interface is using Automatic Private IP Addressing (APIPA).

IPLoopBk


IP Loopback Ping


Pings the IP loopback address of 127.0.0.1.

DefGw


Default Gateway


Pings all the default gateways for each interface.

NbtNm


NetBT Name Test


Similar to the nbtstat -n command. It checks that the workstation service name <00> equals the computer name. It also checks that the messenger service name <03>, and server service name <20> are present on all interfaces and are not in conflict.

WINS


WINS Service Test


Sends NetBT name queries to all the configured WINS servers.

Winsock


Winsock Test


Uses Windows Sockets WSAEnumProtocols() function to retrieve available transport protocols.

DNS


DNS Test


Checks whether DNS cache service is running, and whether the computer is correctly registered on the configured DNS servers. If the computer is a domain controller, DNS Test checks to see whether all the DNS entries in Netlogon.dns are registered on the DNS server. If the entries are incorrect and the /fix option is on, it tries to reregister the domain controller record on a DNS server.

Browser


Redirector and Browser Test


Checks whether the workstation service is running. Retrieves the transport lists from the redirector and the browser. Checks whether the NetBT transports are in the list from NetBT transports test. Checks whether the browser is bound to all the NetBT transports and whether the computer can send mailslot messages. Tests both via browser and redirector.

DsGetDc


DC Discovery Test


Finds a generic domain controller from directory service, finds the primary domain controller, and then finds a Windows 2000 domain controller. If the tested domain is the primary domain, checks whether the domain GUID stored in Local Security Authority (LSA) is the same as the domain GUID stored in the domain controller. If not, the test returns a fatal error; if the /fix option is used, DsGetDC tries to fix the GUID in LSA.

DcList


DC List Test


Gets a list of domain controllers in the domain from the directory service on an active domain controller. If there is no domain controller information for this domain, tries to get an active domain controller from the directory service (similar to DsGetDc test). Gets the domain controller list from the target domain controller and checks the status of each domain controller. Adds them all the to the list of the tested domain.
If the preceding sequence fails, uses the browser to obtain the domain controllers, checks their status, and adds them to the list.
If the DcAccountEnum registry entry option is enabled, NetDiag tries to get a domain controller list from Security Accounts Manager (SAM) on the discovered domain controller.

Trust


Trust Relationship Test


Tests trust relationships to the primary domain only if the computer is a member workstation, member server, or domain controller. Checks that the primary domain SID is correct and contacts an active domain controller. Connects to the SAM server on the domain controller and uses the domain SID to open the domain to verify that the domain SID is correct. Queries information of the secure channel for the primary domain. If the computer is a backup domain controller, reconnects to the primary domain controller. If the computer is a member workstation or server, sets a secure channel to each domain controller listed for this domain.

Kerberos


Kerberos Test


Tests Kerberos protocols only if the computer is a member computer or domain controller and the user is not logged on to a Windows 2000 domain account and not logged on to a local account. Connects to LSA and looks up the Kerberos package. Gets the ticket cache of the Kerberos package and checks whether the Kerberos package has a ticket for the primary domain and the local computer.

LDAP


Lightweight Directory Access Protocol (LDAP) Test


Run only if the domain controller is running directory services and the computer is a member or domain controller. Tests LDAP on all the active domain controllers found in the domain and creates an LDAP connection block to the domain controller, then searches in the LDAP directory with three types of authentication: unauthenticated, NTLM, and Negotiate. If the /v (verbose) switch is on, prints the details of each entry retrieved.

Route


Route test


Prints the static and persistent entries in the routing table, including a Destination Address, Subnet Mask, Gateway Address, Interface, and Metric.

NetStat


NetStat test


Similar to NetStat tool. Displays statistics of protocols and current TCP/IP network connections.

Bindings


Bindings test


Lists all bindings, including interface name, lower module name, upper module name, whether the binding is currently enabled, and the owner of the binding.

WAN


WAN test


Displays the settings and status of current active remote access connections.

Modem


Modem test


Retrieves all available line devices. Displays the configuration of each line device.

NetWare


NetWare test


Determines whether NetWare is using the directory tree or bindery logon process, determines the default context if NetWare is using the directory tree logon process, and finds the server to which the host attaches itself at startup.

IPX


IPX test


Examines the network's IPX configuration, including frame type, Network ID, RouterMTU, and whether packet burst or source routing are enabled.

IPSec


IP Security test


Checks the current status of the IP Security Policy Agent service. It also reports which IPSec policy (if any) is currently active for the computer.

Make sure you mention the different media types at some point. There's no need to mention all the different categories, but I think you should at least talk about the uses for Straight Through and Crossover cables along with Cat5e and Cat6.

I had planned on cover B G and N, as well as CAT5 5e and 6. i hadn't thought about including crossover until i started typing this reply.... consoles use crossover to do a local game, so it would be pertinent. TY

You're desciptions could be much better as far as Hub's/Router's/Switch's and there duties and how they work. Quite a bit of info is missing regarding them as well as what info you have up isn't all accurate.

I have some images in a previous FAQ that show the differences in the wires when comparing a Straight Through cable to a Crossover cable. You're free to use them if necessary.

How to: Make a Straight Through UTP Cat5 cable

I wrote it a couple of years ago when I was still taking my CCNA but it sill applies today.
