IIS Troubleshooting Tips for SCCM Admins|MP DP IIS Error Codes

It is really quick to segregate the IIS HTTP Error Codes, which will be useful when troubleshooting SCCM/ConfigMgr/MEMCM Management Point and Distribution Point – server-related communication issues. In this post, you will find more IIS Troubleshooting Tips.

IIS is integral to SCCM/Configuration Manager server roles like MP, DP, and SUP. Most of the traditional SCCM client and server communication. The most modern touch is via the fast channel and Message Processing Engine (MSP).

IIS Troubleshooting Tips for SCCM Admins| MP DP IIS Error Cheat Codes

The following are the IIS cheat codes I recently saw on Twitter. I thought this made full sense and wanted to share it in this post—all the credits go to the publisher of this slide.

1. Informational

Request received continuing process.

Patch My PC

This class of status code indicates a provisional response, consisting only of the status line and optional headers, and is terminated by an empty line.

Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions.

2. Success

This class of status codes indicates the action requested by the client was received, understood, accepted, and processed successfully.

The HttpSendRequestSync call for port 80 succeeded with a status code of 200. The text response was “OK.” The HTTP test request also succeeded. (IIS Troubleshooting Tips for SCCM Admins|MP DP IIS Error Codes)

3. Redirection

The client must take additional action to complete the request.

This class of status codes indicates that the user agent needs to take further action to fulfil the request. If the method used in the second request is GET or HEAD, the user agent may carry out the required effort without interaction with the user.

A user agent should not automatically redirect a request more than five times since such redirections usually indicate an infinite loop.

4. Client Error

The 4xx class of status code is intended for cases where the client seems to have erred. Except when responding to a HEAD request, the server should include an entity explaining the error situation and whether it is a temporary or permanent condition.

These status codes apply to any request method. User agents should display any included entity to the user. These are typically the most common error codes encountered while online.

5. Server Error

The server failed to fulfil a valid request.

Response status codes beginning with the digit “5” indicate cases where the server is aware that it has encountered an error or is otherwise incapable of performing the request.

Except when responding to a HEAD request, the server should include an entity explaining the error situation and indicating whether it is temporary or permanent. Likewise, user agents should display any incorporated entity to the user. These response codes apply to any request method.
