If you’re using an automated tool to create your user accounts and assign a Home Folder (a mapped drive pointing to shared location on a server) - make certain that the property has a colon after the drive letter (e.g. Z: not Z). Without the colon, the drive will not be mapped on user log on. How do you know if this property is set correctly? Active Directory Users and Computers won’t show you. Use ADExplorer. This tool will show you the properties, value types, and actual values of any object in your Active Directory structure…very helpful for writing scripts and apps that interface with LDAP.
