I had an issue (still have an issue) with the global catalog in our domain. There is a template file that somehow got corrupted and caused the global catalog for our domain to not function. I worked with Microsoft for quite some time, and for now the temporary fix was to create another child domain on-site with a working global catalog.
Since Microsoft got their paws on my domain controllers things haven't been right. Now my two domain controllers aren't replicating computer and user accounts between themselves. Because of this weird things are happening that users are noticing. Does anyone know how can I resolve this or at least narrow down the problem?
