RESOLUTION

To resolve this problem, use the Microsoft Visual Basic Scripting Edition (VBScript) code in this section to disable name resolution for the ISA Server routing rules. To run this code, follow these steps:

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

1. Start Notepad, and then paste the following VBScript code in Notepad:

   ' 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 
   WScript.Echo "Done!"
   

2. Click Save on the File menu, and then follow these steps in the Save As dialog box:
   1. In the Save as type list, click All Files.
   2. In the File name box, type FileName.vbs.
3. Copy the .vbs file to the ISA server, and then double-click the .vbs file to run the VBScript code.
4. Click OKwhen you are prompted.

You can also create a DWORD value in the registry to resolve this problem. To manually create the DWORD value, follow these steps:

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following key in the registry:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fpc\Storage\Array-Root\Arrays\{D6380CBF-B892-4EC8-B30D-4361DABEBE9D}\ArrayPolicy\WebProxy

   Note The value {D6380CBF-B892-4EC8-B30D-4361DABEBE9D} represents an ID that is specific to your installation. This ID may be different on your computer.
3. Right-click WebProxy, point to New, and then click DWORD Value.
4. In the right pane, type the following name for the new value, and then press ENTER:

   msFPCSkipNameResolutionForAccessAndRoutingRules

5. Right-click the DWORD value, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Exit the registry.
