Symptom：
Access to any computer through \\ip or \\< computer name > will appear "the network path not found" error, unable to access the cyber source, but can access the external web page.
The final solution:
Netsh interface IP reset c:\log.txt operation command to reset the tcp/ip components to the initial state, to solve the problem after restarting the computer.
Problem solving steps:
1, check the physical connection: because the symptoms
described access to external web page no problem, so this step can be skipped.
2, Ping 127.0.0.1 loopback address is normal, indicating that tcp/ip protocol installation (basic state) no problem.
3, Ping the other computer name and IP address are normal (including large useful data packets to Ping), there is no packet loss, indicating the basic connection with the computer (including the connection between the card and the computer itself) and network name resolution no problem. The physical layer to the network layer are not the problem, the application layer protocol problems.
4, check the network settings: check on TCP/IP protocol bundled with NETBIOS (in the TCP/IP protocol properties - Advanced - WINS - enabled TCP/IP NETBIOS selection); check if you have to install the Microsoft file and print service component, other computers must also start with "file and print sharing, and check the Microsoft client network setup. This examination is normal.
5, check whether to start a "Computer Browser service computer browser WIN2K/XP, to ensure that the computer browsing service to ensure the normal start, can participate in web browsing and the host declared the election. Open computer management, services and applications, services, see the "Computer Browser" has not been stopped or disabled. This examination is normal.
6, no band network, Windows XP computer must enable the guest
guest account, because did not join the domain of the Windows XP default will visit the computer account is equivalent to the guest account, after examination, the other is access to the computer's guest account is disabled, but after the opening of the fault is still.
Describe relevant policy settings:
1) in order to choose the "computer configuration, security settings, Windows settings, local strategy, security strategy options network access: sharing and security model for local accounts, the default settings" - guest only local users authenticate as guest "changed to" classic: the local user in its own authentication". The use of Windows XP this strategy can make access to computer users access the Internet through the computer, you can log in with their own "identity". The default setting is only a guest Windows XP, windows 2003 and windows xp join domain default settings for the classic.
2) in the "classic: the local user to enable authentication in their own way, can limit the number of access to shared files and users, and can set different permissions for different users. But the user's password is empty, access will be rejected. It is necessary to check the security options to "account: use a blank password for local accounts only allow for the console login" strategy is enabled, enabled by default, according to reject the principle of priority, the computer password is empty the user through the network access using Windows XP will be banned.
7, check whether the computer is allowed to access the account:
Lai Bin looked all the local security settings of the computer whether to allow Guest (Lai Bin) account to access the local computer from the network. In the local security policy manager gpedit.msc,
In order to choose the "computer" and "Windows configuration settings", "local policy" to "user rights assignment", "refused access to this computer from the network, whether contains the GUEST account check strategy, if there is deleted.
8, to ensure that the built-in firewall is access to the machine did not open: open the local connection properties > advanced, turn off the Internet connection firewall. If you use the third party firewall, refer to the relevant manuals, ensure the firewall does not disable the UDP-137 and UDP-138, TCP-139 and TCP-445. This check, all the computers were not open the firewall service.
9, check the RPC Plug and, Play service is started, following the re registration of the dynamic link library:
Regsvr32 netshell.dll
Regsvr32 netcfgx.dll
Regsvr32 netman.dll
By the examination of RPC and Plug and play services have been started, and successfully re registration of the dynamic link library above.
10, is probably the last system Tcp/ip component damage or missing in the windows 98/2k computer can directly uninstall and then reinstall this agreement, and in the windows xp/2003, because Tcp/ip is a core component of the system, not only directly uninstall, reset, reset the Tcp/ip and related components to a clean state. In the command line window input Netsh interface IP reset c:\log.txt (where log.txt is the state of the log file name, specify the command generated can be arbitrary). After the restart, troubleshooting.
Summary:
After so many wrong steps, finally will fix a command, but the essential troubleshooting steps correctly. Netsh and some other important functions listed below several Netsh commands some common sub functions and methods of use, other more detailed usage please see windows help and support.
1, for the specified IP address and gateway network interface
The following command will be named Local Area Connection configuration interface, the static IP address is 192.168.0.2, subnet mask of 255.255.255.0 and default gateway for
192.168.0.1:
C:\>netsh interface IP
Netsh interface ip>set address name= "Local Area Connection" source=static addr=192.168.0.2 mask=255.255.255.0
gateway=192.168.0.1
2, reset the Winsock directory for the blank.
C:\>netsh Winsock reset
3, for the specified DNS network interface
The following command will be named Local Area Connection configuration interface, the DNS address is 192.168.0.3:
C:\>netsh interface IP
Netsh interface ip>set DNS name= "Local Area Connection" source=static addr=192.168.0.3 ddns=enabled suffix=interface
4, reduction of Tcp/ip and related components to a clean state
C:\>netsh interface IP reset c:\log.txt
Reset Tcp/ip and command execution log output to c:\log.txt.。
