[Samba] Samba server dropping off the domain

[Don Krause]

Yup, we lasted almost 2 weeks this time, then all of a sudden,

[2012/01/20 10:53:00,  3] rpc_client/cli_netlogon.c:573(rpccli_netlogon_set_trust_password)
  rpccli_netlogon_set_trust_password: unable to setup creds (NT_STATUS_PIPE_DISCONNECTED)!
[2012/01/20 10:53:00,  3] rpc_client/cli_netlogon.c:573(rpccli_netlogon_set_trust_password)
  rpccli_netlogon_set_trust_password: unable to setup creds (NT_STATUS_PIPE_DISCONNECTED)!
[2012/01/20 10:53:00,  3] rpc_client/cli_netlogon.c:573(rpccli_netlogon_set_trust_password)
  rpccli_netlogon_set_trust_password: unable to setup creds (NT_STATUS_PIPE_DISCONNECTED)!

I rejoined to domain, and it's working again.

And no error message on the samba side either.  So I took out my sledge hammer and pounded the square peg into the circle hole with a crontab to rejoin to the domain every 10 minutes.  I found I do not need to stop and restart samba for this.
