operation system Windows XP home edition.
Had no problems then I suddenly get the below issue when trying to log in.
The system cannot log you on now because the domain STUDY is not available.
STUDY is the name of my domain.
However when logging in SAFE mode with networking I am able to log in to the account!
Any easy answers to this issue?
