Carrying on from my IIS admin via a web service work, i needed to apply IPSecurity restrictions to some of the sites that would be created.

Plently of googling revealed some information about an IISIPSecurity class in .NET 3.0 and above, but i could only rough c# sample code here , and that was for a console app

so after many failed attempts to convert to VB.NET to work with my web service, and even tried the ADSIIIS.dll com interop, i gave up and converted the c# code into an assembly , which works. I know hind sight is 20:20, but i shodul have just done that in the first place

my code is here

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.DirectoryServices;
using System.Reflection;
namespace IISSecurity
{
public class IISIPSecurity
{
static string SetIPSecurityProperty(string metabasePath, string member, string item)
{// metabasePath is of the form “IIS://<servername>/<path>”
// for example “IIS://localhost/SMTPSVC/1″
// member is of the form “IPGrant|IPDeny|DomainGrant|DomainDeny”
// item is of the form “<ipaddress|domain>”, for example, 157.56.236.15 or domain.microsoft.com try
{
if ((“IPGrant” != member) && (“IPDeny” != member) && (“DomainGrant” != member) && (“DomainDeny” != member))
{
 return “Failed in SetIPSecurityProperty; second param must be one of IPGrant|IPDeny|DomainGrant|DomainDeny”;
}else{
 DirectoryEntry path = new DirectoryEntry(metabasePath);
 path.RefreshCache();
 object ipsecObj = path.Invoke(“Get”, new string[] { “IPSecurity” });
 Type t = ipsecObj.GetType();
 Array data = (Array)t.InvokeMember(member, BindingFlags.GetProperty, null, ipsecObj, null);
 bool exists = false;
 foreach (object dataItem in data)
 {
if (dataItem.ToString().StartsWith(item))
 {
 exists = true;
 }
}
if (exists)
{
 return “Not appling already exists”;
}
 else
{
 object[] newData = new object[data.Length + 1];
 data.CopyTo(newData, 0);
 newData.SetValue(item, data.Length);
 t.InvokeMember(member, BindingFlags.SetProperty, null, ipsecObj, new object[] { newData });
 path.Invoke(“Put”, new object[] { “IPSecurity”, ipsecObj });
 path.CommitChanges();
 path.RefreshCache();
 ipsecObj = path.Invoke(“Get”, new string[] { “IPSecurity” });
 data = (Array)t.InvokeMember(member, BindingFlags.GetProperty, null, ipsecObj, null);
 }
 return “OK”;
}
}
catch (Exception ex)
{
 return ex.Message;
}
}
}
}
