I have 2 AD servers (one master) on Windows 2008 STD, but when the master AD is down, user PCs are unable to login to the domain on the backup AD server.
The master and backup AD are defined in AD. User's PC are pointing to the AD servers for DNS and WINS (AD servers run DNS and WINS as well). All User PCs are Win XP Pro SP3.
Any suggestions where I should start looking at ? Thanks.
