"welcome" is showed but cannot log on in Vista 5472

[Guest]

I've installed the Vista Beta 5472. At first everything goes normally,
but after some times I cannot not log on. After inputing my passwords,
"welcome" is showed in the middle of the screen, and I wait and wait and
wait, but nothing happens. What I can do is to restart my computer and log on
adminstrator account throuh safe mode.
Now, only the adminstrator account under the safe mode is available.
Could you tell my how to solve this problem?

PS:I feel Vista is not reliable at all at this time. During the first 3
hours after installation, my computer restart 3 times unexpectly.

I had the same problem, I reinstalled the OS and started putting programs
back on 1 by 1. After installing eTrust® EZ Antivirus software and
encountered the same thing again. I booted into safe mode and uninstalled it
and Vista booted normal...is anyone else having the same problem

I got the same problem with eTrust. I'm running Trend Micro as an alternative.
