1 сервер win 2003,AD,DNS,DHCP,wins...
2 win2003sp1,isa 2004,RRAS
второй подключен к домену,
какбы всё работает но на втором вот такие ошибки:
1.This computer was not able to set up a secure session with a domain controller in domain IECC due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.

ADDITIONAL INFO
If this computer is a domain controller for the specified domain, it sets up the secure session to the primary domain controller emulator in the specified domain. Otherwise, this computer sets up the secure session to any domain controller in the specified domain.
2.The kerberos subsystem encountered a PAC verification failure. This indicates that the PAC from the client inet$ in realm IECC.LC had a PAC which failed to verify or was modified. Contact your system administrator.
нетбиос включен, RPC разрешен, на исе всё настроено как надо...

А с чего ты взял ДНС ?
Оно вроде свою ф-ю выполняет нормально...

ты прав, но DC вполне нормально существует, и остальные компы его прекрасно находят с первого раза.
