If you want to do an LDAP query you can use ldp.exe (installs with ADAM). Do the query and see what kind of error you get - ldp is great at showing you all the behind the scenes stuff. -Brian

The application should log the error, not the DC. You can use netmon or wireshark to monitor ldap traffic. I think you can turn up LDAP debugging to such a ridiculous level that those get logged, but you'll flood your DCs. And yes, use adfind (www.joeware.net) or dsquery (already on your windows 2003 servers). Regards, Michael B.

Example: We have an application that will remain nameless but rhymes with HP Quality Center. LDAP import settings points to our "Portland Users" OU. If U rename the OU - which will break the LDAP config - will the DC log any attempt to talk to "Portland Users"? Additionally, does anyone have (or know of) a simple app that I can throw in my test environment to test such activity? I can't test the production stuff and have no dev environment for this particular scenario...
