Today, using the intranet to deploy Web services, using mobile phone access (mobile phone access to the Intranet Server Web page, see the previous blog),
The basic steps are as follows:
1.visual Studio generates a Web service and deploys it to a folder in WS
2. Server IIS in the Web site, right-click Add a new Web site ws, directory location 1 in the directory WS (add site process requirements set as shown in the site name, path, binding IP, and other content. Once IP is bound, access will be accessed by IP))
When you access the service, "" HTTP error 503 appears. The service is unavailable "error page
3. Continue with the following settings: In an application pool that automatically generates "WS" (generated automatically by a Web site of 2), locate the WS application pool, right-click menu and select Properties, select the 4.0 framework (generated in Visual Studio using 2010 of the 4.0 framework), managed pipeline mode selection "Classic" and tick "start Application pool Now" (to ensure that the application pool is running and not running will not see the effect)
4. Subsequent access to the service will appear
At this point click Site Zs, and in "IIS" in "Directory Browsing"
Under Actions, click Enable, this button will become disabled, you can eliminate this error
5. Configure the right-hand server, in the features view, double-click ISAPI and CGI restrictions to confirm that the WEB service extension is set to allow.
Tisp:
A, if the extension is not in the list, in the Actions pane, click Add.
B. In the Add ISAPI and CGI Restrictions dialog box, type the path to the. dll or. exe file in the ISAPI or CGI path box, or click Browse to navigate to the location of the file.
C. In the Description box, type a brief description of the limit.
D, (optional) Select Allow extension path to be allowed to run automatically.
E, if you do not select this option, the throttling status will be disallowed, which is the default state. You can select this option at a later time and click Allow in the actions pane to allow the limit. Click OK.
6. If you cannot browse the Web service, right click on the site right-click Program Pool – Advanced settings, drag down, in the process model has identified an item, click on the following ellipsis, in the pop-up window "built-in Account" dropdown, select "NetworkService", OK.
Well, after a few steps, both the computer and the phone can access the

Introduction to the IIS_WPG user group
in order to control The IIS_WPG group (also known as the IIS Worker process group, IIS workers process Group", and its members include the Local System (LocalSystem), Local service, network Service (Network Service) and IWAM account. The members of the IIS_WPG have the appropriate NTFS permissions and the necessary user permissions that can act as the process identity for worker processes in IIS 6. The following locations have permissions assigned to IIS_WPG:
? %windir%\help\iishelp\common– Read
? %windir%\iis Temporary Compressed files– list, read, write
? %windir%\system32\inetsrv\asp Compiled template– Read
? Inetpub\Wwwroot (or content directory)-Read, execute
In addition, IIS_WPG has the following user rights:
? Ignore traverse check (SeChangeNotifyPrivilege)
? Log on as a batch job (SeBatchLogonRight)
? Access this computer from the network (SeNetworkLogonRight) Therefore, the network Service account provides access to the above location, sufficient permissions to act as a process identity for the IIS 6 worker process, and permissions to access the network.
All IIS6 processes are run under the IIS_WPG account.
In addition, in the process of finding information, found I want to prove a long time, and never confirm the words, help us understand the HTTP protocol of the underlying implementation, in the following blue http Loop description of the ground body
503 Error503 is an HTTP status code. English name 503 Service Unavailable and 404 (404 Service Unavailable) are the same as a Web page status error code. The former is a server error return status, the latter is a Web program does not have the relevant search results returned after a state, need to optimize the site often need to make 404 error pages for the overall site optimization.

any client that communicates with your network server needs to go through the following loops:
obtain an IP address from your site's IP name (that is, your Web page address-URL, without the start of ' http://'). This correspondence (that is, the correspondence between IP names to IP addresses) is provided by the Domain name server (DNSS). Open an IP socket (socket) to connect to the IP address. Writes the HTTP data stream through the socket. The HTTP data stream that receives the response from your network server. The data stream includes a status code whose value depends on the HTTP protocol. Parse the data stream to get status coding and other useful information. This error is generated in the last step described above, when the client receives an HTTP status code and recognizes it as ' 503 '. 3reason for occurrenceWeb page appears1.

Solution:To resolve this issue, follow these steps: 1. Verify that the application pool has been configured for the virtual server. The default application pool is MSSharePointPortalAppPool. Follow these steps to determine the application pool that the virtual server is using. A. Click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager. B. Expand ServerName, expand Web Sites, right-click the virtual server, and then click Properties. C. Click the Home Directory tab. The application pool configured for the virtual server is listed in the Application pool box. D. Click OK. 2. Verify that the password used by the application pool account is correct. IIS does not automatically poll for password changes in the ActiveDirectory directory service. If the application pool account is a domain account and its password has expired, you may receive the error message that is described in the "Symptoms" section of this article after you reassign a new password for this account. 3. Verify that the application pool account is a member of the IIS_WPG group and the STS_WPG group on the server. 4. Restart IIS to reclaim the application pool.4WorkaroundYour Web server is actually in the "shutdown repair" state. It still runs at a minimum because it can respond to at least 503 status codes, but full service is not possible, that is, your website is unavailable. There are a number of possible causes, but in general, it is due to the human intervention of your Web server operator. Usually you should know that someone is trying to resolve the problem and that the normal service will be restored as soon as possible. Please contact the system operator on your site to determine why the service is stopped. Compared with us, they will be better able to help you solve such errors.
