Step 7: Now that you can close the Command Prompt, please open the registry (regedit) and go to the following:

Create a new dword value and name it OptionValue and specify a value of 1. Close regedit.

Step 8: Run the program, select Cryptographic Services, change the startup type to Manual, and apply, but don't start the service! (Note:.)

If you start this process before, cryptographic

services are turned off, then skip this step. )

Step 9: Restart your computer.

1) If it is a problem with the broadband itself, first directly connect to the broadband network cable for testing, and if it is a problem with a wide cavity band, contact the broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. After there is a factory reset and it can be used from the new settings (this is under the premise that the physical connection is correct, sometimes it is caused by the slow or failed IP address search of the router, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

5) If the browser is not easy to use, it is recommended to test it with Google Chrome, this browser is very easy to use.

6) If you have any questions, please ask me.

There are two kinds of file directories on the company's shared server: one is the external file directory; Second: the internal file directory (which can only be accessed by logging in with the domain).

In order to avoid the trouble of logging out of the current system and switching to a domain account login, there is the net use command, which can help us access the "domain" directory without logging out of the system.

.net use format: the visited directory of the net use server user: domain name domain login.

Example: I am currently logging in to the operating system as a native user, but I want to be able to access the domain's folders, follow these steps:

1) Delete the existing connection to avoid the appearance of "one user uses." multiple connections".

net use * /delete

If the message "List is empty" is displayed, there are no associated connections. If it says, "You have a remote connection as follows. Continuing to run will disconnect", enter "y" or "y".

2) Log in to the domain through the net use command (the process of obtaining permissions) to achieve the purpose of normal access to the domain.

net use Administration Department Administration Department Internal folder user:jiesai zhuyongfeng

Note: Spaces and slashes are required in commands.

3) If you are asked for a password, enter the domain login password.

.net use is used to connect a computer to a shared resource, or to disconnect a computer from a shared resource.

When using this command without options, it lists the computer's connections.

net use command in detail net use ip ipc$" " /user:" "Establish an IPC null link.

net use \\ip\ipc$ "Password" /user:"Username"Establish an IPC non-null link.

net use h: \ip\c$ "Password" /user:"Username"After logging in directly, map the other party's c: to the local as h:

net use h: ip c$ after logging in, map the other party c: to the local h:

net use ip ipc$ del to remove the ipc link.

net use h: del deletes the h:map mapped to the other party locally.

With this knowledge in hand, it is easy to understand the meaning of the output information of the above command.

The first one is to list the remote connections for this computer.

The second is to map the other party C: to the local for D: after logging in directly, because the local D: is in use, and all the output of this device is already in use.

The third is to map the other party C: to the local as Z: after logging in directly, there are many reasons why the output cannot find the network path, such as:

Wrong IP address; The target is not powered on; The target lanmanserver service is not started; The targets are firewalls (port filtering) and so on.

But a check will find the error.

If you have any questions, please feel free to ask!

Other details are not related to this question and will not be listed in detail, you can refer to the information:

The reasons are summarized in the following aspects, which occasionally appear, point: cancel, you can!

1.The computer has been hit by a Trojan horse or a virus is interfering! Try antivirus

2.If the first method doesn't work, open: "360 Security Guard", "Trojan Horse Killing": "360 System First Aid Kit"!

First "Start First Aid", after the investigation is completed, delete the "suspicious startup items" and Trojan horses, and then restart the computer!

Then click on the "File Recovery Area", find the "Suspicious Startup Items" and the Trojan, and click "Delete Files Completely"!

Then click "System Repair", "Select All", and then click "Repair Now"! Network Repair, Fix Now, Restart Your Computer!

10.If you really can't do it, "one-click restore" the system or "reinstall the system"!

There are many aspects of this phenomenon, one is the hardware, that is, the memory problem, and the other is the software, which has many problems.

One: Let's talk about hardware first: Generally speaking, computer hardware is not easy to break. There's not much chance of a memory problem (unless your memory is really a ragtag mess), and the main aspects are:

1。The memory module is broken (mostly second-hand memory).

2。Memory with quality issues was used, 3. The gold finger part of the memory plugged into the motherboard is too dusty.

4。Different brands of memory with different capacities are used, resulting in incompatibilities.

5。Thermal issues caused by overclocking. You can use memtest to check the memory, which can thoroughly detect the stability of the memory.

Second, if there are none, then troubleshoot from the software side. First of all, it is recommended:

1. Check whether there are Trojans or viruses in the system. Such programs often modify the system irresponsibly in order to control the system, resulting in operating system abnormalities. In general, we should strengthen our awareness of information security and never be curious about unclear executable procedures.

2. Update the operating system, let the installer of the operating system copy the correct version of the system file, and correct the system parameters. Sometimes there are bugs in the operating system itself, so pay attention to installing the official upgrade program.

3. Try to use the latest official version of the application, beta version, and trial version, which will have bugs.

4. Delete and then recreate the files in the Winnt System32 WBEM Repository folder: Right-click on My Computer on the desktop, and then click Manage. In"Services and Applications", click Services, and then close and stop the Windows Management Instrumentation service.

Delete all files in the Winnt System32 WBEM Repository folder. (Create backup copies of these files before deleting them.) ) to open"Services and Applications", click Services, and then open and start the Windows Management Instrumentation service.

When the service restarts, these files are recreated based on the information provided in the following registry key: hkey local machine software, microsoft wbem cimom, autorecover mofs
