Problem Logging on to Domain

As a new hire, my laptop was logged on to my company's domain by my admin. I later created a hardware profile which I did use on my peer-to-peer home network . When I attempted to join my office domain I was given no option to either log on locally or join the company domain.

I had to get an admin to logg me onto the domain. The next time I used my laptop on my home network and then afterwards tried to join the company domain,again I was unable to join the domain. This has happened several times and my admin is quite puzzled?? Any suggestions? Thanks so much!!
