Dim SecObj

Dim MyIPSec


' Get the IIS object that holds the info for the default site.

' This could be any site root/vdir, or IIS://LocalHost/W3SVC for global

' properties.

Set SecObj = GetObject("IIS://LocalHost/W3SVC/1/Root")

' Get the IIsIPSecurity object

Set MyIPSec = SecObj.IPSecurity

If (TRUE = MyIPSec.GrantByDefault) Then

Response.Write

"<BR>GrantByDefault was set to TRUE. Setting to FALSE.<BR>"

MyIPSec.GrantByDefault = FALSE

Else 'If (FALSE = MyIPSec.GrantByDefault) Then

Response.Write

"<BR>GrantByDefault was set to FALSE. Setting to TRUE.<BR>"

MyIPSec.GrantByDefault = TRUE

End If


' Set the info in the database

SecObj.IPSecurity = MyIPSec

SecObj.Setinfo
