Almost 20 years back? Not everything was remote accessible, or accessible remotely for external consultants. The software required dedicated hardware cards. This often resulted in different servers being used and general hands off from IT. Sometimes because they where marked simply as Telco.
The times I walked around with a borrowed IT badge, got left in a room I didn't have access to or IT blocked a door from shutting are countless.
Sometimes, in small companies, they didn't give a flying fuck. Other times, in banks or international institutions, it was lawful good rule breaking. Like, here have my badge because we are still battling internal why my colleagues don't have access.
