Currently my company is running SBS 2003 / Exchange with about 30 users. I've been having trouble with one particular user lately. This user uses a machine that was previously occupied by someone who left the company. Every now and then, the current user won't be able to open certain files or download certain things. I'm pretty sure it's a permissions issue, so my question is what would be the easiest way to make them an admin or primary user of this machine? Thanks for the help.
