Hello,
I actually have 2 domain controller acting as a primary and secondary DC/DNS. I would like to be able to turn off the primary domain controller without affecting the network. Since my netapp is the host for all my home directory, I would like it to be able to switch back and forth without major downtime.
I have tested it, and with my current configuration, it takes about 5 min to lookup 1 username.
Network configuration :
2 windows 2003 R2 DC/DNS with unix compatibility acting as PDC/secondary
Windows Home directory/profile :
cifs share on netapp
unix home directory:
nfs share on netapp
Netapp sees my windows domain as a windows 2000 domain and sees both DC. I have both setup as favorite dc
This is the trace I get when I shutdown the PDC and I try to access a share on netapp:
AUTH: slow rsp - Get password by UID (xxxx) took 115032 msecs to complete
AUTH: LSA lookup: located account "domain\user" in domain "domain"
AUTH: TraceLDAPServer- Attempting to improve AD DLAP connection for FQDN

CIFS: Warning for server \\pdc: connection terminated.

NBT: Cannot connect to server x.x.x.x over NBSS socket for port 139. Error 0x23 Resource temporarily unavailable.
AUTH: slow rsp - Get group list by name (user) took 200001 msecs to complete
most of the trace repeate themself from that point.
Login time for a windows account : 14:38:13 to 14:50 until windows timeout and fail to find my profile.
I can ssh to a solaris box and access my nfs home directory, as well as cifs shares from that box. It is slow though.
I understand that this will rarely happen but I would had hoped for something a bit faster then that. Is there something to do about it?
