[Samba] RPC Server Unavailable Message

[Asai]

Greetings,

We've been testing Sernet Samba AD and are running into trouble with the 
RPC server unavailable message when trying to edit group policy and 
manage users with Windows 8.1.  Upon restarting the service, we can 
connect to the RPC server, but after 24 hours or less, we can no longer 
connect.  I've been trying to find more information about this issue, 
which was apparently fixed awhile back, but I can't really find much on 
it.  Please let me know how I can help resolve this issue.

Our smb.conf is as follows:
# Global parameters
[global]
         workgroup = AVALON
         realm = AVALON.LOCAL
         netbios name = LOCALHOST
         server role = active directory domain controller
         server services = rpc, nbt, wrepl, ldap, cldap, kdc, drepl, 
winbind, ntp_signd, kcc, dnsupdate, smb
         dcerpc endpoint servers = epmapper, wkssvc, rpcecho, samr, 
netlogon, lsarpc, spoolss, drsuapi, dssetup, unixinfo, browser, 
eventlog6, backupkey, dnsserver, winreg, srvsvc
         idmap_ldb:use rfc2307 = yes
         #kerberos method = system keytab

[netlogon]
         path = /var/lib/samba/sysvol/avalon.local/scripts
         read only = No

[sysvol]
         path = /var/lib/samba/sysvol
         read only = No

[Users]
         read only = No
         path = /var/samba/Users
