NIS broken after installing patch cluster on Solaris 10

Hi,
I installed Solaris 10 recommended patch cluster (patch bundle of 400+ patches). After reboot global zone is fine, but a lot of services was in uninitialized state. I had to run /lib/svc/bin/restore_repository and then services came online.
Now I can't login to server with NIS account because this server can't get any output from ypwhich, though connectivity seems to be okay to both NIS master servers.

# ypwhich
Domain pre.dcpoint.com not bound on e522-db23-prod.
# domainname
pre.xypoint.com
# svcs nis/client
STATE STIME FMRI
online 18:13:35 svc:/network/nis/client:default
