LAN visits - [ Network]

     LAN visits - [Network] Therefore, neighbors can not visit each online exhibition. Symptoms: Ping the computer from the computer to pass, but can not access shared resources, in the Solution: In Control Panel - Administrative Tools - Services start the Server service. And set 2, IP settings are correct. Symptoms: no interaction between the dual-Ping, twisted-pair connections have been tested with no problems,mac makeup, no firewall. Solution: Check whether the two computers in the same IP network segment, there are sub-mask are the same. 3, WINXP default settings are not correct. Symptom: can not access from another machine on WIN98/2000/2003 WINXP machine. Solution: In the Then enter secpol.msc running start Local Policies -> User Rights Assignment, open the Also sometimes encounter another situation: Access XP, when the user name in logon dialog box is gray, is always Guest users can not enter the other user accounts. Solution: Local Policies -> Security Options -> the security policy. Symptoms: In the user rights assignment, open the 5, the firewall rules. Symptom: Install a firewall (including the WINXP system comes with a firewall), there can not Ping-pass, or when access to shared resources prompted to Please contact the administrator of this server to find out if you have access, Solution: Stop the firewall or add the local network access rules. WINXP built-in firewall: Open the Control Panel - 6, Win2000/XP with Win98 visits Symptoms: Ping command can be passed, but not in the Solution: In WIN2000/XP system: Control Panel - Account is disabled Guest under the rumored Windows XP users have serious security flaws, but also in the But here they can: in the In the Well, now we give you the user to set up a password for it Guest. The way to the top of the hook is also marked with it. 1. Access permissions are set incorrectly Windows NT/2000/XP/2003 systems support NTFS file system, NTFS can be used effectively enhance the security of the system, but in the ACL (access control list) in the setting of user access is not the time, can lead the user can not normal access to the local shared resources, a 2. Account and Policy Working Group set up properly in the Windows environment, under normal circumstances, the user should use the Guest account to access shared resources. But to the system's security, disable the Guest account of the system, in addition, in the Windows 2000/XP/2003 systems, Group Policy default Guest account is not allowed to access this computer from the network, so that other users can not access led to the machine's shared resources, an 3. Network firewall set up properly the user in order to enhance the security of the machine to prevent illegal intrusion, the installation of the network firewall. However, the firewall settings on the network properly, also lead to other users can not access the shared resources of the machine, an Solution 1. Enable Guest account in many cases, to the local system security, Guest account is disabled, so the machine can not access the shared resource, it must enable the Guest account. The author introduces Windows XP system as an example. Sharing of resources in the end, go to the If the Guest account a red crosses, indicating that the account has been disabled, right-click the account in the Guest Properties dialog box, remove the to enable the Guest account. This method is suitable for Windows 2000/XP/2003 systems. Tip: Use the Guest account to access shared resources, there is a big security risk. Of course, we can create for each access to a specified user account. First of all shared resources in providing end to create a new account, and then specify the account access. Then you want to access the shared resource in a new client the same user account name and password, log on the client using this account, the account can be allowed normal access to the shared resource. This method is more secure, but for the network to create an account for each user, not suitable for larger networks. 2. Although the user access policy change enabled the Guest account the machine, but users still can not access the shared resources provided by the machine, it is because the default group policy does not allow Guest account to access the machine from the network. Click the ), in the right column to find This would use the Guest account to access the machine from the network shared resources. This method is suitable for Windows 2000/XP/2003 systems. 3. Reasonable set of user access network, many machines use the NTFS file system, it features ACL (Access Control List) can control user access to the user to access the shared resources of these machines must be given the appropriate permissions Caixing. If using the Guest account to access the machine CPCW shared folder, right-click the shared directory, choose to be given to If you want more than one user account can access the shared directory, just add Everyone account, and then give This method is suitable for use NTFS file system Windows 2000/XP/2003 systems. 4. To change the network access mode XP default is to log all users from the network are handled by the guest account, so even if the log from the network administrator only has guest privileges, if the situation could not have access, try changing the network access mode. Open the Group Policy Editor, select authenticate as Guest This, if not open guest, you can also enter the local account and password to log on to your computer to access the local account and password to access the computers you want to have the account and password. If you need access to the network account and password, you can enter your computer to access the existing account and password to login. If a change of access mode, you may even enter a user name and password are not possible, / / ​​computername / guest for the gray is not available. Even if the password is blank, without opening the case guest, you can not point to determine login. Into classic mode, you can enter a user name and password to log you into the computer. 5. Many machines properly configured network firewall network firewall is installed, it set incorrectly, the same result users can not access the shared resources of the machine, then the machine will open the NetBIOS ports required for sharing resources. Author Skynet firewall, for example, in the 6. A note of caution that we may encounter another problem, that is, when the user's password is empty, even if you do all of these changes still can not log in, access or will be rejected. This is because, in the system, users network access when using the Windows XP computer will be banned. Disable this policy as long as we can solve the problem. In the Security Options, find After the above change the base to access, you can try to choose a method for you. Add the following points in the other problems you may encounter. 7. Network neighborhood can not see the computer may often not be seen in the network neighborhood to access your computer unless you know the name or IP address of the computer, through a search or enter / / computername or / / IP. Please address the following operations: start If you stop this service, you are neither updated nor maintained the list. 137/UDP--NetBIOS name servers, network basic input / output system (NetBIOS) Name Server (NBNS) protocol is TCP / IP on a NetBIOS (NetBT) protocol suite forms part of the NetBIOS name based on available hosts on the network access Name and address mapping. 138/UDP--NetBIOS Datagram, NetBIOS datagram is a TCP / IP on a NetBIOS (NetBT) protocol family part of it used for network login and navigate. 139/TCP--NetBIOS session service, NetBIOS session service TCP / IP on a NetBIOS (NetBT) protocol family part of it for the Server Message Block (SMB), file sharing and printing. Please open the corresponding firewall ports. As long as the firewall allows the general folder and printer sharing services on it. 8. On the shared mode to shared XP will only give the guests the default permissions or choose to allow users to change the Windows 2000 operating system, users set up folders in the shared property of operation is very simple, just right-click the folder with the mouse and select Properties, you can see the sharing settings tab. Windows XP system settings in the shared folder is more complex when the user can not see the above procedure to share the Settings tab. Specific modifications as follows: Open Modified so users can use Windows 2000 as the folder as easy to modify properties. 9. On the Network Neighborhood access with no response or slow response to problems in WinXP and Win2000 Network Neighborhood to browse the system delay of 30 seconds by default, Windows will use this time to search the remote computer has the specified scheduled task (or even possible to Internet search.) If the search does not respond when the network will fall into the waiting restrictions, then the delay of 10 minutes or an error is not surprising. The following is the specific solution: turn off the WinXP service plan tasks (Task Scheduler) can go to , then set the startup type to Summary can not access mainly due to the default XP does not open the guest, and even opened a guest, XP by default does not allow guest to access the computer from the network. There is someone worthy of attention. I believe that are not considered a safe place, or do computer company gives the system password is empty, but it is not allowed to login. Just tried the above method, I believe is no longer a problem. General In these cases recently, belong to the same domain in the computer, others are visiting his computer, but he is unable to access other people's, but he visited a number of other computers. And the other computer ping will not pass, but could not find with the IP address lookup, and he did not open the firewall and the like, is this how is it? Please figure it out, so ing ... ________________________________________ Windows Network Neighborhood visits the basic conditions: 1) the parties to open the computer, and set up a network of shared resources; 2) the parties added a computer services; 3) the parties are properly set up net IP address, and must be in a segment; 4) both computers are turned off the firewall, or firewall policy did not prevent the Network Neighborhood access strategy. Windows 98/2000/XP/2003 access to XP's user authentication is enabled first and foremost about Guest Why can not access the questions: 1, by default, XP Guest account is disabled 2, by default, XP's local security policy prohibits users from the network Guest Interview 3, by default, XP's Local Security Policy -> Security Options, the not only local network access from the landing, Guest empty password by default ...... So, if you need to use XP if Guest user access to the above three settings: Enable Guest, Guest modify the security policy allows access from the network, 3 inside the security policy to disable or to add a password Guest. Another situation sometimes encountered: Access XP, when the user name in the logon dialog box is gray, is always Guest users can not enter the other user accounts. The reason is that security policies are at play (Administrative Tools - By default, XP's access method is Therefore, the easiest way to access XP is: do not enable the Guest, just modify the above security policy for the XP to connect other systems to access their account information entered. As for the visit in 2003, is disabled by default in 2003 Guest, but did not hate the default XP that way guests share contradictory, so you can directly enter the username and password access. A small office LAN, all winxp systems, can be on the outside network, the computer can see each other but can not see each other tips shared computer network path is not correct, or you do not have permission to use the network probably mean I remember not sure! ! I have enabled Guest account! winxp firewall is turned off, ip address is also no problem! ! Hope to analyze! ! Thank you very much! Reasons: Win2000/XP security policy restrictions exist. Sometimes, Win2000/XP Network access to this computer > remove the Win2000/XP and Win98 visits if two computers are using Win2000/XP operating system, then set up local area network is a very simple and easy thing, when the hardware connection is completed, normally once in the see each other. However, if there is a computer local area network using Win98, it may not necessarily the case, we often find that although the Ping command can be passed, but still not in the Strategy One: enable the Guest user in Win2000/XP. In Win2000/XP system will be installed to create two user accounts by default, that Administrator (System Administrator) and Guest (guest account), all has not been assigned to the local computer user account will default Guest account, which there is no password. However, the default settings, the Guest account has not been enabled, we can from the Open the In fact, enable the Guest account, the biggest benefit is when Win2000/XP from Win98 to access does not require a username and password, this method is more suitable for the user uncertainty, the larger local area network traffic, but for home users to that do not apply. -------------------------------------------------- ----------------- Strategy II: Check whether there is Win2000/XP security policy restrictions. Sometimes, Win2000/XP Policy | User Rights Assignment to add or delete. -------------------------------------------------- ----------------- Strategy three: Disable the firewall on the local connection. A firewall is to act as network and the outside world to defend the border between the security system, Microsoft WinXP for users with a built-in Internet Connection Firewall (ICF), some insecurity after the opening to restrict information from the external into the internal network. However, if you are in the local connection is enabled on the firewall, it will not result in exchange of visits between the working group, there and the administrator of this server to find out if you have access, -------------------------------------------------- ----------------- Four Measures: In order to add NetBEUI protocol WinXP. In fact, the NetBEUI protocol is added directly to solve the problem sometimes but not more visits easier, and it can solve the above-mentioned problem of the firewall is enabled. Win98 automatically installed when you install NetBEUI protocol, but WinXP is no longer available technical support for NetBEUI protocol,mac brushes, so only manually added. Identify the WinXP installation CD into the file is optional. However, INF folder has the hidden attribute, WinXP users need to first under the -------------------------------------------------- ----------------- five measures: Enable Win98 in the This is a very simple but often overlooked problem, although the machine is equipped with Win2000/XP from the Of course, in addition to various reasons mentioned above, there are two computers is not in the same workgroup, or the computer's internal IP address of the two clashed, even Hub fault, line fault and so on. Question: My Network Places client access server, a Enter the IP address directly the same. Possible: IPC $ does not open or virus. Solution: Method 1: Run Net Share IPC $ command, or directly to the Net Share IPC $ adding boot entry in the registry RUN. Method 2: The% Systemroot% SYSTEM32 following a WUAMGRE.EXE file, delete it. Method 3: installing a Trojan nemesis, anti-virus. Do not agree with this view. Not a good way to enable the guest. microsoft in xp, 2003 etc in the default settings on the guest, not superfluous. Network Neighborhood access to a lot of problems, here are several: 1, can not get online list of hosts in addition to the local neighborhood issues, should check whether the machine can access the browser or the domain controller also hosts the following reasons: browser itself is the problem (do not use AD , 98 and other host situation), the problem domain controller GC (using AD case). If the local area network or the host browser is having browser service disabled, you will have this situation. If you are using a LAN switch broadcast restrictions, you should use wins service. The problem can be nbtstat query browser, but better is to use the win2k installation CD browstat tools, browser use browstat sta show host, with the elect to force a new election browser. For the AD, you can use the nslookup query 2, My Network Places only part of the host list, or list of hosts is wrong. Possible causes include browser is being replaced, some of the host's own set of hidden (such as the registry LanmanServer Parameters Hidden = 1), part of the host can not broadcast (limit switches, etc.). Reference to the above solution. 3,mac makeup wholesale, visit to the host, but the host is not accessible (no path). If you use the wins, or the dns, check their analysis is correct, local lmhost, hosts file content is correct, clear the netbios cache of the machine, or the arp cache. With the ip address can access. 4, browse the host authority is not enough,vibram 5 fingers, or do not appear to enter a user name and password. Should check the local login account and password if the account has in the other host, the other account lockout is enabled, if an account has been connected to the resources (even if not visited, it is possible), you can use net use ip ipc $ / d, first remove any account to connect, and then access, such as using net use ip ipc $
