IFPCWebProxy::SkipNameResolutionForAccessAndRoutingRules property

Article
08/27/2012

Applies to: desktop apps only

The SkipNameResolutionForAccessAndRoutingRules property gets or sets a Boolean value that indicates whether the Forefront TMG Web proxy will skip name resolution while checking access and routing rules. When name resolution is disabled in a forward proxy scenario with chaining, requests requiring DNS lookup on the downstream Forefront TMG computer are sent directly without delay to the chained upstream computer.

This property is read/write.

Syntax

HRESULT put_SkipNameResolutionForAccessAndRoutingRules(
  VARIANT_BOOL fSkipNameResolutionForAccessAndRoutingRules
);

HRESULT get_SkipNameResolutionForAccessAndRoutingRules(
  VARIANT_BOOL *pfSkipNameResolutionForAccessAndRoutingRules
);

' Data type: Boolean

Property SkipNameResolutionForAccessAndRoutingRules( _
  ByVal fSkipNameResolutionForAccessAndRoutingRules As VARIANT_BOOL, _
  ByVal pfSkipNameResolutionForAccessAndRoutingRules As VARIANT_BOOL _
) As Boolean

Property value

Boolean value that indicates whether the Web proxy will skip name resolution while checking access and routing rules.

Error codes

These property methods return S_OK if the call is successful; otherwise, they return an error code.

Remarks

This property is read/write. Its default value is False (VARIANT_FALSE in C++).

After the value of this property has been modified, the change must be written to persistent storage by calling the Save method, and the Microsoft Firewall service must be restarted for the change to take effect. For more information about restarting the Firewall service to apply changes, see Restarting Services After Configuration Changes.

This property cannot be set through Forefront TMG Management.

Examples

This VBScript script sets the value of the SkipNameResolutionForAccessAndRoutingRules property so that the Web proxy will skip name resolution while checking access and routing rules. This script does not include error handling.

' Create the root object.
Dim root  ' The FPCLib.FPC root object
Set root = CreateObject("FPC.Root")
' Declare the other objects needed.
Dim isaArray     ' An FPCArray object
Dim webProxy     ' An FPCWebProxy object
Dim restartMask  ' A 32-bit bitmask of type FpcServices
' Get references to the array object
' and the Web proxy object. 
Set isaArray = root.GetContainingArray()
Set webProxy = isaArray.ArrayPolicy.WebProxy
' Configure the Web proxy to skip name resolution
' while checking access and routing rules and save
' the new configuration. 
webProxy.SkipNameResolutionForAccessAndRoutingRules = True
restartMask = webProxy.GetServiceRestartMask
webProxy.Save
' Restart the Firewall service so that
' the change will take effect.
isaArray.RestartServices restartMask
