Hi! I installed Windows Vista without any problems on my Desktop. Now I tried installing it on my Laptop, but everytime Vista boots and I try to log on it just says: "Windows Security" (title) "The specified domain either does not exist or could not be contacted." What am I doing wrong? I didn't select a domain, nor was I able to find out how. I tried Safe Mode, and the Startup Repair program, but nothing helped. I see two accounts on startup: Administrator and Guest. I can't log-on to either. Any ideas? Thanks in advance! Paul
