Problem description

I believe that many students in accordance with some technical videos or blogs to learn SCCM server is that the installation is configured, but in the test there will always be some inexplicable problems, so on the network according to the error prompt to search, spent more than N time but slow progress, but often can not find effective solutions, even if found a solution to this problem, and then encounter similar problems do not know where to start.

Analysis of problems

When we encounter a problem, most of us are used to searching the Internet according to the error prompt, and then try it one by one until the problem is solved, and then it is solved. Maybe the next time a similar failure occurs, our processing process remains the same, without the network in hand, there will be no bottom in the heart.

Solution method

The best way to enable people to improve their technical ability to solve problems quickly and effectively is to understand the application scenarios, use appropriate tools to assist in investigation, and summarize and share problems.

1. Understand the application scenario.

Deployment of SCCM server, for us to do IT, application in the enterprise domain environment, the biggest visible advantage is that the system can be deployed in batches, patching and other centralized management.

When deploying the system through PXE, the general process is as follows: the startup image and installation image are required to be deployed on the deployed SCCM server, the function of deploying the system through PXE is enabled, the installation sequence is created and distributed for the required computer clients, and so on.

two。 Use the right tools.

When actually dealing with problems, limited by time and experience, our fastest way is to directly copy and paste error prompts and then search, so which keyword and which search engine will be more effective?

The following figure shows the error message of the client computer when deploying the system through PXE. There are a lot of error messages. Everyone basically knows that the keyword to be searched is the error code, that is, 0xc000000f:

Then let's compare the results of using different search engines. The keyword I use is 0xc000000f pxe sccm.

Baidu is forced to use in China, the related result is 60, if you open one by one for reference the quality of the document is mixed:

Little-known Bing, this has a domestic and international version, generally we choose the international version. Among the 306000 related results, most of the cases mentioned by keywords are included, and the probability of finding a solution to the problem is much higher. Personal experience, if it is Microsoft's product problem, using the international version of Bing is the best choice, not only because Bing supports its own product line well, but also because it can be visited normally in China.

Google, which can only be used under certain circumstances, has only 2520 search results, but the degree of matching is very high. I heard that Google is going to return to China, and I'm really looking forward to it. The good use of things doesn't depend on advertising to really test the efficacy.

To sum up, we probably know that in the current situation, we can choose Microsoft's Bing International search as the preferred search tool.

3. Summarize and share

After some search and experiment, the problem is finally solved. What we need to do at this time is to organize and share our homework, which is a process of knowledge internalization. In the process of dealing with problems, we pay more attention to the results and often ignore some details, and we will think back and forth in the process of sorting out technical documents. the missing details often become the anchor of the thought of the person you understand to help you through ex post summary and thinking, thus forming your own set of logical thinking and solutions. The biggest benefit of sharing is that in addition to benefiting people with similar problems, you will also get some feedback, which may be a skill boundary that can be expanded by looking at, thinking about, and solving the same problem from another perspective.

An error 0x80070490 was reported in the process of deploying the PXE system in the case.

1. I enter the keyword 0x80070490 in Bing, and then automatically display search recommendations related to this keyword:

two。 I choose the default 0x80070490 sccm osd, the first recommended keyword combination, and then access the first item of the result to open:

3. The IT technology sharer wrote out in great detail the problems he encountered and the solutions, along with the corresponding pictures, simple and clear. The biggest thing I learned in his blog post is how to view the log in this interface, locate the problem in the log according to the error code, and then solve the problem. If I report another error message on this interface later, I will know how to read the log to solve the problem, and I don't even have to ask for help and search.

4. In this blogger's article, it is mentioned how to enter the command line in the error reporting interface, hit F8 to open CMD (command prompt), that is, you can open the command line tool by pressing F8 on the current interface. But in practice, it will not work by default. We need to check Customization-Windows PE Scatch Speace (MB)-Enable command support (testing only) when distributing the startup image:

Of course, the troubleshooting process of the PXE deployment system mentioned here is only to attract jade. Mastering the troubleshooting process and the fundamental way to solve the problem is the key. When a problem is encountered, it can accurately locate the problem and solve it efficiently.
