How to lookup an unknown GUID in Active Directory

For this tutorial we will use an old but perfectly functioning tool called "ldp.exe" which is available after installing ADDS - although there are other options available like "LDAP Admin" and so on.

To begin launch ldp.exe (from the DC), select Connection >> Connect and enter the appropriate hostname / IP of the target DC along with the port.

Once conneced we go to Connection >> Bind and enter our AD accoun information.

We can then go to View >> Tree and enter our base DN - which should be our domain e.g.:

DC=domainname,DC=com

Then right-hand click on the domain DN in the tree and select "Search." For the "Base DN" field we will enter: <GUID=GUIDNUMBERHERE>, in the "Filter" field we will enter: objectclass=* and select "Subtree" in the scoping options and finally run.
