AccessFlags

The AccessFlags property contains flags for configuring file access permissions, which are defined in the Flags section. The last four flags augment the first four flags in that they relate to access granted to remote computers. You can enable local access without remote access, but you cannot enable remote access without local access.

Metabase properties can be configured programmatically using three different technologies in various different languages (see Comparison of IIS Administration Features). For basic code examples, see the sections under Using IIS Programmatic Administration. More complicated, task-based code examples are provided in Using IIS.

The following code example configures the AccessFlags property to allow read and script access to clients browsing the default Web site. This example uses uses ADSI in VBScript. ADSI is special in that it can refer to flags as properties. This code shows how to configure any DWORD (or Long) property.

Dim lAccessFlags 
Set IIsWebServerObj = GetObject("IIS://localhost/W3SVC/1") 

' Store original value: 
lAccessFlags = IIsWebServerObj.AccessFlags 

WScript.Echo("Before: AccessFlags = " & IIsWebServerObj.AccessFlags) 

' There are multiple ways to set a property: 
IIsWebServerObj.AccessRead = True 
IIsWebServerObj.Put "AccessScript", True 
IIsWebServerObj.SetInfo 

IIsWebServerObj.GetInfo 
WScript.Echo("After: AccessFlags = " & IIsWebServerObj.AccessFlags) 

' Restore to original value: 
IIsWebServerObj.Put "AccessFlags", lAccessFlags 
IIsWebServerObj.SetInfo 

IIsWebServerObj.GetInfo 
WScript.Echo("Restored: AccessFlags = " & IIsWebServerObj.AccessFlags) 

The following code example configures the AccessFlags property to allow read and script access to clients browsing the default Web site. This example uses WMI in JScript. This code shows how to configure any DWORD (or Long) property.

IIS 5.1 and earlier: WMI cannot be used.

var lAccessFlags; 
var providerObj = GetObject("winmgmts://localhost/root/MicrosoftIISv2"); 
var IIsWebServerObj = providerObj.get("IIsWebServerSetting='W3SVC/1'"); 

// Store original value: 
lAccessFlags = IIsWebServerObj.AccessFlags; 

WScript.Echo("Before: AccessFlags = " + IIsWebServerObj.AccessFlags); 

IIsWebServerObj.Properties_("AccessFlags").Value = 513; 
IIsWebServerObj.Put_(); 

IIsWebServerObj.get; 
WScript.Echo("After: AccessFlags = " + IIsWebServerObj.AccessFlags); 

// Restore to original value: 
IIsWebServerObj.Properties_("AccessFlags").Value = lAccessFlags; 
IIsWebServerObj.Put_(); 

IIsWebServerObj.get; 
WScript.Echo("Restored: AccessFlags = " + IIsWebServerObj.AccessFlags); 

Client: Requires Windows XP Professional, Windows 2000 Professional, or Windows NT Workstation 4.0.

Server: Requires Windows Server 2003, Windows 2000 Server, or Windows NT Server 4.0.
