Windows 98/2000 / XP / 2003 Access XP user authentication problem
First on why Guests cannot be accessed:
1. By default, XP disables guest account 2. By default, XP's local security policy prohibits guest users from accessing 3, by default, XP Local Security Policy -> Security Options, Account: Upload password Users can only log in to "is enabled, that is, any account of the empty password can only log in locally from the network, Guest default empty password ...
So, if you need to use the guest user to access XP, you want to perform the above three settings: Enable guest, modify the security policy allows guest to access, disable 3 security policies or give guests.
Sometimes it will encounter another situation: When accessing XP, the username in the login dialog is gray, which is always a guest user, and cannot enter other user accounts.
The reason is that this security policy is in the monsters (management tools -> local security policies -> Security Options -> "Network Access: Local Account Sharing and Security Mode"). By default, XP's access method is the way "only guest", then you access it, of course, you cannot enter other user accounts for GUEST.
So, accessing the easiest way to access the XP is: No need to enable guest, only modify the above security policy is "classic". Other systems access XP can enter account information.
As for accessing 2003, by default 2003 disable guest, but there is no XP that hate the default contradictory guest mode sharing, so you can enter your username password access.
Win2000 / XP and WIN98
If the two computers use the WIN2000 / XP operating system, the formation of a local area network is a very simple and relaxing thing. When the hardware connection is completed, it can see the other party in the "online neighbor" under normal circumstances. However, if there is a computer in the LAN where you use Win98, it can be not necessarily, we often find that although the ping command can pass, but still unable to implement an interview in "online neighbors", what should I do?
Countermeasure 1: Enable guest users in Win2000 / XP. Two user accounts are built by the Win2000 / XP system after installation, that is, Administrator, and Guest (guest account), all users who are not assigned to the account will use the guest account by default, the account There is no password. However, under default settings, this guest account is not enabled, we can find the "Guest" account from "Control Panel | Administrative Tools | Computer Management | Local User and Group | User", and right-click "Guest Property dialog, removing the hook tag on the "Account Deactivated" check box here, which can be accessed from Win2000 / XP from Win98 after exiting.
In fact, after the Guest account is enabled, the biggest benefit is that the username and password are not needed from the WIN98, which is more suitable for the user's uncertain, a large number of visitors, but for home users. Speaking is not applicable. -------------------------------------------------- ---------------- Countermeasures 2: Check if there is security policy restriction in Win2000 / XP. Sometimes Win2000 / XP "smart" overhead, although we have enabled guest accounts, from Win98 but still unable to access Win2000 / XP, then from "Control Panel | Management Tools | Local Security Policy | Local Policy | User Right Assignment Find "Access this computer" or "Reject this computer from the network" or "Reject this computer", then check if a guest account or other corresponding account is displayed, and then add or delete it according to different situations. -------------------------------------------------- ----------------- Countermeasures 3: Deactivate the firewall on the local connection. The firewall is a security system that acts as a security border between the network and the external world. Microsoft provides users with a built-in Internet Connection Firewall (ICF) in WinXP. After enabling, some unsafe information can enter the internal network from the outside. However, if you enable this firewall in your local connection, you will cause you unable to visit each other, "XXX cannot be accessed", "You may have no permission to use network resources", "Please contact this server Administrators contact similar prompts such as visiting whether you have access, "Can't find the network path", at which point local connection is disabled. -------------------------------------------------- ---------------- Countermeasures 4: Add NetBeui protocol for WinXP. In fact, directly adding the NetBeui protocol to solve the problem that the problem that cannot be visited is sometimes more simple, and it can solve the problem of the enabled firewall mentioned above. The NetBeui protocol is automatically installed when Win98 is installed, but since WinXP no longer provides technical support to NetBeui protocols, it can only be added manually. Find the WinXP installation CD, enter the "ValueAdd / MSFT / Net / NetBeui" folder, here there is nbf.sys, netbeui.txt, netnbf.inf a total of 3 files, first copy the nbf.sys file to this machine " Windows / System32 / Drivers "folder (this machine here) is installed in WinXP's computer), then copy the Netnbf.inf file to the" Windows / INF "folder of the unit, NetBeui.txt files can be None. However, INF folders have hidden properties, and users need to select display files in WinXP "Tools | Properties" windows to see this directory. -------------------------------------------------- ---------------- Countermeasure 5: Enable "File and Printer Sharing" in WIN98. This is a problem that is very simple but often ignored. It is a machine with Win2000 / XP. Although it can find Win98 machine from "online neighbors", it is impossible to access, because Win98 is not enabled "allowed" This option can be solved by other users to access my files.
