【 Weak current College 】 LAN visits six classic problem

On the local network cannot exchange topic has always been very concerned about network management, recently raised similar issues users are also quite a lot, mainly Windows98 cannot access WindowsXP or Windows2000 or WindowsXP cannot access WindowsXP, below for these visits failure solution do a review.

Question 1: how to use hardware exclusion method
Use the ping command to see NIC lamp method to verify that the hardware or software.
Check the network lights, if one is not lit, there is a problem with the network card. If only the network signal is off, click on "start → run" and type "ping each other IP-t" (actually entered without quotation marks), if prompted consecutive four "Requesttimeout" (request suspend//timeout), describes the physical line access or network is too busy causing obstruction. Available line instrument further check the network cable and network head, troubleshoot them one by one.

Question 2: what about the lack of agreement
LAN visits required protocol: TCP/IP (IPX/SPX as necessary, Novell network and some network games to set the Protocol), NetBIOS.
1.NetBIOS protocol
WindowsXP is not supported in the default NetBIOS Protocol, but now many are small network using the Protocol. Add method as follows:
(1) copy the WindowsXP installation CD Valueadd\MSFT\Net\netbeui directory nbf.sys file to the system directory in the; \system32\Drivers
(2) copy the netnbf.inf to system \lnf directory, and then add protocols like usually do operations on it (in my network places have corresponding add protocol options, in the optical drive into the Windows installation disc you can also directly add).
2.NetBEUI protocol
The communication protocol is Windows95/98 from the times, has no WindowsXP such agreements (but still relevant file NetBEUI on WindowsXP CD), there must be some LAN can access the network NetBEUI some or all of the information on your computer, you need to do to install NetBEUI. Methods are as follows:
In WindowsXP installation CD into the "ValueaddMsftNetNetbeui" directory will be copied to the C:\Windows\INF Netnbf.inf; the Nbf.sys copied to C:\Windows\System32\Drivers; tap "Start → Control Panel → Network places", choose "network connections", "LAN connection" and press the right button, choose good content; in the "General" this item, tap the "install → communication protocol → add", you can see the "select NetBEUI NetBEUIProtocol", then press OK.

Issue 3: Setup error handling
Determine all the computer's IP are on the same network segment, determine all computers are in the same working group (or domain) to change the workgroup, if your computer is already a member of a domain, you should have an administrator will separate you from the domain and to deactivate your account with your computer. Want to modify the working group you must be logged on as an administrator.
In addition, make sure your firewall is not set too high a level, or they may turn off the necessary communication ports, it is recommended that you turn off and then try it out.

Issue 4: installation services?
In order to achieve shared aims to install the "Microsoft network file and print services" on the essential. Steps are as follows: turn into "local area connection → control panel → properties → install", "select network component type" dialog box, click the "add services" → "select network service" dialog box, click the service you want to install.

Question 5: do you want to distinguish between domain network
LAN including band domain and domain of the two, in the case of a domain network, but also in the "network" properties of "primary network logon", select "Microsoft network users" guarantee domain name filled out correctly.

Question six: account not to do
As with the external network, you do not enable the Guest account is recommended, if only used within the local network, you can directly access enabled, so it would be convenient, but there are many considerations.
1. open the Guest user
Password can not set, so you can just enter the account Guest, you can log in (visits). But the need to ensure that the following policy.
Click on "start → run" and enter "gpedit.msc" and open the group policy. Then click on the "computer configuration → Windows Settings → Security Settings → Security options in local policies →" found "accounts: use of blank passwords for local user to console logon only." When enabled, you cannot use an empty password access, disable it.
2. lifting Guest
(1) open the group policy, then click on the "computer configuration → Windows settings → security settings → local policies → user rights assignment", "deny access to this computer from the network," a double-click, if there is no Guest, please delete.
(2) are still in the group policy, in the "access this computer from network" double-click on items, see any Guest, if not, please add.
(3) remains in the group policy, then click on the "computer configuration → Windows Settings → Security Settings → Security option" double-click "Network access: sharing and local account in safe mode ", the default settings" → guest only-local users authenticate as guest "changed to" classic-local users authenticate as themselves. "
In addition, if you only see WindowsXP PC file directory, but you cannot access the folder. This is because the default is the file WindowsXP simple shared methods can be modified: in the "Explorer", click "Tools → folder options", "view" tab, "Advanced settings" in the "use simple file sharing (recommended)" to remove the front hook.
