HTTP 500 Internal Server error resolution

If it doesn't work out, you can browse: HTTP 500-Internal server error (supplemental content)

Q: When the debugger goes wrong, why do some machines always have an "HTTP error 500.100-Internal server error-ASP error", and cannot display specific error messages?

Reason:

IE browser settings to screen out the specific error information.

Solve:

1, choose IE browser-tools--internet options.

2. Remove the "Show friendly HTTP error message" Check in the Advanced Options box.

If the above method does not work, we can continue to look down

1. Run: regsvr32%windir%/system32/vbscript.dll (in fact, this step can also save, to ensure that in case, or execute it)

2. Operation: Msdtc-resetlog

3. Reinstall IIS

Comments:

1. Microsoft has only provided a management script adsutil.vbs with IIS5, which is located in the c:inetpubadminscripts subdirectory, registering Vbscript.dll first.

2. Msdtc.exe is a Microsoft Distributed Transport Coordinator program. The process calls the system Microsoft Personal WEB Server and Microsoft SQL Server, which is used to manage multiple servers, and must ensure that the service starts properly.

(1) Control Panel-> management Tools-> Component Services

(2) Locate "Component Services"-> "Computer"-> "My Computer"-> "COM Application"-> "IIS out-of-process Pooled"

3. If you cannot find IIS out-of-process pooled applications, or if you click on a COM application that cannot be opened, and then finish msdtc-resetlog, reinstall IIS.

If the above method does not work, we can continue to look down

The specific operation in three steps, all need to log on to the computer as an administrator to provide sufficient operational rights (IWAM account to Iwam_myserver for example).
　　
(i) Change the password for the Iwam_myserver account in Active Directory
　　
Because IWAM account password by the system control, randomly generated, we do not know what, in order to complete the following two steps of the password synchronization work, we have to IWAM account password set to a value we know.
　　
1. Select Start-> program-> Administrative Tools-> Active Directory Users and Computers to start the Active Directory Users and Computers snap-in.
　　
2, click "User", select the right "Iwam_myserver", right-click Select "Reset Password (T) ...", in the pop-up Reset Password box to iwam_myserver set a new password, here we set to "Aboutnt2001" (no quotes), OK, wait for password modification to succeed.
　　
(ii) Synchronization of passwords for Iwam_myserver accounts in IIS metabase
　　
Perhaps because of the sensitivity and importance of this change, Microsoft has not provided an explicit user interface for us to modify the Iwam_myserver account password in IIS metabase, only with IIS5 provided a management script adsutil.vbs, which is located in C: Inetpubadminscripts (location may vary depending on how you install IIS5).
　　
The Adsutil.vbs script is powerful, has a lot of parameters and is complex to use, and only provides a way to modify the Iwam_myserver account password using this script:
　　
adsutil SET W3svc/wamuserpass Password
　　
The "Password" parameter is the new password for the IWAM account you want to set up. Therefore, the command to modify the password for the Iwam_myserver account in IIS metabase to "Aboutnt2001" is:
　　
C:inetpubadminscripts>adsutil SET w3svc/wamuserpass "Aboutnt2001"
　　
After a successful modification, the system will have the following prompts:
　　
WAMUserPass: (String) "Aboutnt2001"
　　
(iii) iwam_myserver password for synchronizing COM + applications
　　
To synchronize the iwam_myserver password used by COM + applications, there are two options: one is to use the Component Services MMC snap-in and the other is to use the IWAM Account Synchronization script Synciwam.vbs.
　　
1. Use Component Services MMC snap-in
　　
(1) Start Component Services Snap-in: Select Start-> run-> MMC, start the admin console, open the Add/Remove snap-in dialog box, add the Component Services snap-in.
　　
(2) Locate "Component Services"-> "Computer"-> "My Computer"-> "COM + application"-> "Out-of-process Pooled Applications", right-click "Out-of-process Pooled Applications the "->" attribute.
　　
(3) switch to the Flags tab of the Out-of-process Pooled Applications Properties dialog box. This application runs under the following account "This user" in the selection is selected and the username is "Iwam_myserver". These are all defaults and do not have to be changed. Enter the correct password "Aboutnt2001" in the "password" and "Confirm password" text boxes below to confirm the exit.
　　
(4) If the system prompts "the application is created by more than one external product." Are you sure you want to be supported by these products? "is OK.
　　
(5) If we set some other Web application protection to high (standalone) in IIS, the IWAM account password for the COM + application used by the web will also need to be synchronized. Repeat (1)-(4) step, synchronize the other corresponding out of process application IWAM account password.
　　
2, use IWAM Account Synchronization script Synciwam.vbs
　　
In fact, Microsoft has found that the IWAM account in the password synchronization problem, so in the IIS5 management script for IWAM account password Synchronization write a script synciwam.vbs, this script is located in C: Inetpubadminscripts (location may vary depending on how you install IIS5).
　　
Synciwam.vbs script usage is simpler:
　　
cscript Synciwam.vbs [-v|-h]
　　
The "-V" parameter represents the entire process of displaying script execution in detail (recommended), and the "-H" parameter is used to display simple help information.
　　
We want to sync iwam_myserver account password in COM + application, only need to execute "cscript synciwam.vbs-v", as follows:
　　
cscript c:inetpubadminscriptssynciwam.vbs-v

Updating applications:
　　
Name:iis out-of-process Pooled Applications Key: {3D14228D-FBE1-11D0-995D-00C04FD919C1}
　　
As you can see from the execution of the above script, using Synciwam.vbs scripts is more comprehensive and quicker than using Component Services. It first finds the IWAM account "Iwam_myserver" from the IIS Metabase database and takes out the corresponding password "Aboutnt2001" and finds all the defined IIS applications and out of process Applications and synchronizes the IWAM account password for each out of the process applications application.
　　
When using the Synciwam.vbs script, be aware that before you run Synciwam.vbs, you must ensure that the IIS metabase database is consistent with the IWAM password in Active Directory. Because the Synciwam.vbs script obtains the password from the IIS metabase database instead of the IWAM account from Active Directory, if the password in the IIS metabase is incorrect, The password obtained by the Synciwam.vbs will also be incorrect, the synchronization operation to the "Updating Applications" system will report a 80110414 error, that is, the application is not found { 3D14228D-FBE1-11D0-995D-00C04FD919C1} ".
　　
OK, so far, IWAM account in active Directory, IIS metabase database and COM + application three passwords have been synchronized successfully, your ASP program can also run!
