SUMMARY

You can use the MetaAcl.vbs tool to modify the default permissions that are set on an Internet Information Services (IIS) metabase.

You might have been redirected to this Microsoft Knowledge Base article from the following IIS error message:
System.Web.Hosting.HostingEnvironmentException: Failed to access IIS metabase. The process account used to run ASP.NET must have read access to the IIS metabase (e.g. IIS://servername/W3SVC). For information on modifying metabase permissions, please see http://support.microsoft.com/?kbid=267904.
You receive this error message because the permissions to the metabase are insufficient, or because the permissions are set incorrectly.

To help resolve this error, use the MetaAcl tool to modify the metabase permissions. For more information about the MetaAcl tool and about how Access Control Lists (ACLs) work, click the following article number to view the article in the Microsoft Knowledge Base:

Note If you are using ASP.Net 2.0 and you must grant metabase permissions to a Windows user account, do not use the MetaAcl tool. Instead, run the ASP.NET IIS Registration Tool command together with the -ga option. For example, the following command grants the Windows user account <WindowsUserAccount> permissions to the IIS metabase:
aspnet_regiis -ga <WindowsUserAccount>
Warning If you edit the metabase incorrectly, you can cause serious problems that may require that you reinstall any product that uses the metabase. Microsoft cannot guarantee that problems that result if you incorrectly edit the metabase can be solved. Edit the metabase at your own risk.

Note Always back up the metabase before you edit it.
