Any one done this? I have a small comapany that is running 2000 SBS on a decent machine. They are using Exchange/Active directory and things are working fine. Someone added a SBS2003 machine to the network and have been using it without any problems…until recently. The users were logging in to 2003 SBS and accessing the 2000SBS from there(which they also had to log on to in order to get email, files, etc. I want to take out the 2003SBS, which is running active directory, and add a 2003 server standard edition. The 2003 stadard will not be running active directory, it will only be acting as a file server and maybe an app. server as well. Can I load the machine and simply join it to the 200SBS domain?
