In my last question is was suggested that for large Active Directory databases that the ADODB method should be used over the GetObject method. I'm not sure I fully understand the difference between these methods.

Could someone please show some samples of these methods, comment on the code involved, and  elaboate as much as possible on when each is to be used?

Thanks,

JB

When I'm trying to work with user objects, I use the ADODB method to get the users Distinguished Name.  Once I have the DN stored in a variable, I can use the GetObject method to get all of the properties of that particular object.

If there are 200 objects in an OU I'm trying to work with, it seems best to use the ADODB method inside a loop.  It allows me to cycle through the objects and then use GetObject to work with each object as it comes through the loop.

Does that help?

Ok... so I guess I got the complete wrong impression that the ADODB and the Get Object methods were mutually exclusive?

They kind of work hand in hand.  You can get by with running ADODB queries to retrieve information, and it *does* enumerate a lot faster than many GetObject calls, but, if you want to change properties of object, you must "bind" to the object using GetObject, then modify the properties.

An article such as this show you both of these methods at work:
