Hello All:
     Did anyone ever control IIS IPSecurity withIISIPSecurity ? I will 
code a program to control IIS Access IP.

the sample code:

IISIPSecurity *pSecurity=NULL;
IISIPSecurity *pSec;
SAFEARRAY *psa;

if(ADsGetObject(L"IIS://localhost/MSFTPSVC/1/ROOT/IPSecurity",
	IID_IISIPSecurity,(void**)&pSecurity)) {
     ShowMessage("test");
     pSecurity->put_GrantByDefault(0);
     //....
}
When I compile the program , it result in link error.
Unresolved external '_IID_IISIPSecurity' referenced from C:\PROGRAM 
FILES\BORLAND\CBUILDER6\PROJECTS\test\unit1.obj
