ASP w/ Active Directory

I'm not sure about this, but can ASP interact with Administrative functions on a Win2k server? Such as Active Directory Users and Groups?

Not directly. You'll need a COM object (.dll) to do so.

Good Luck

Not trying to get you to write my code or anything (like some people), but what kind of .DLL? Make one in VB and then use it on a webserver through ASP?
I'm kind of lost as how you would do this? Do you know anyplace that goes in depth about .DLLs and interacting with win2k? Thanks for your help.

Try this. It should give you a listing of active directory objects. Replace "LDAP://SERVER/dc=DOMAIN,dc=COM" with appropriate server and domain info. Any username/password combination with privileges to access the directory can do this.
