Login Error 3004-304 aix 4.3 please help

hello, I am trying to log on and get an error "3004-304 You are not allowed to login at this time.".
The server is in production level, works as a cluster under hacmp, the other server took the services but I cannot log into the first one.
Please help me because I need to solve the problem as soon as possible.
Thank you very much.

Can you give some details, please?

Which user account did you use to log on? (root or other)
What does your machine use as authentication method? (local, Kerberos, DCE, LDAP, something else)
Do you run NIS?

Have you checked :
/etc/security/login.cfg
/etc/security/user
/etc/security/user
/etc/utmp
/var/adm/wtmp
/etc/security/failedlogin

I hope this helps.

Hello bakunin, yes I run NIS, I logged on with root user.
Finally I could solve the problem! I'd just restarted some services from the other node of the cluster.
Thank you very much!
