Hi. NT4 server environment. Central site, Primary site & 5 scondary sites feeding into Primary. Due to a hardware failure 1 of the secondary sites has been rebuilt. I have deleted the site from the hierarchy, re-installed SMS on the secondary server but when attempting to add into the hierarchy I am told that <site code> is already installed. I have been through this process a couple of times removing the SMS software from the secondary site using the Q234484 article details. Any thoughts? Is the Master site control file causing this?
