I work at a large private school. The library is a shared resource with another government school next door. For years this has worked having computers physically connected to the switch going to whatever domain it was joined to. Recently, due to political and historical reasons, they want all computers in the area to be able to log on to either domain. In other words, all computers now will be assets belonging to both schools, and any computer in the library is to be used by students in either domain.
Needless to say, neither I nor the sysadmin next door are too excited about this. At this time, the only connection between the two networks is a multi-homed sql server. I'm reasonably experienced in network support, but have never needed to do this.
I know companies merge all the time, but we don't have people resources to do a large scope of work. Thankfully we're not a merger, but do need to 'merge' the library as a shared resource between the separate campuses. How easy is this to implement with regards to security, functionality, routing, etc.? How large scope of works is this, or is there a simple solution?
