Client has two domains residing on the same subnet/physical network. Essentially there's just a POP3 mail server (
OLDSERVER) and one of the old DCs (
OLDDC) on life support to keep
OLDSERVER happy. There is no trust established between the two forests; they're not aware of each other's existence.
I want to temporarily mount a mapped drive via
net use to
NEWSERVER so I can run a file sync job over the course of a few nights to get all the mail data off of the old server, but I'm getting trust relationship errors, regardless of how the domain is specified with the
I'm reasonably certain that if I changed the DNS server bindings on
NEWSERVER or maybe added a forwarder for the old FQDN to the
OLDDC, I could possibly get this to work, but I'd rather find a command line method of specifying which DC to query/authenticate against so that I can map a drive temporarily; thinking out loud, a hostfile entry for the required DNS entries for the old domain, resolving to the
OLDDC required may be a potential solution too.
Another alternative may be just to install a temporary FTP server and avoid SMB/Windows-based authentication altogether (or just use a USB drive), but I'm more curious than anything right now to know if this is possible.
EDIT: HOSTS file method will likely not work as SRV records are not supported. For non-SRV aware clients, you can specify a particular A record, but I would suspect that non-SRV aware clients would not include Windows Server 2008 R2; from an MSDN blog article on required DNS records for Active Directory:
GC IP Address -
Allows a non-SRV-aware client to locate any Global Catalog server in the forest by looking up >an A record. A name in this form is returned to the LDAP client through an LDAP referral. A >non-SRV-aware client looks up this name; an SRV-aware client looks up the appropriate SRV >resource record.
Net Logon also registers a DNS CNAME (alias) record for use by Active Directory replication >The Locator does not use this record.
