I recently began working at a company and basically had to walk into their network blind. They have two servers. There were two new systems that needed to be joined, but for some reason they won't. The other weird thing is that a few computers can log onto the domain, and browse the network, but can't be pinged from anywhere. Users can log on with the two new systems as well, but can't browse any of the workstations, or servers in the domain. I don't know what's goin on, and if there are any tips anyone could offer, I'd really appreciate it. Thanks!
