SMB, domain name, WTF?

[jmaister]

Had a little run-in with a SMB setup that a amateur dropped the ball on.

When would you need Domain name for SMB?

I managed to compare settings with the new, and the old. The only difference is the D name missing, no authentication needed what so ever.

I've had about +100 encounters, this is case #2.

I believe the only time would be in a domain environment where the MFP has to log in as a domain user. Not 100% sure though.

If your client is using DHCP for the Computers, and you're setting up a Scan to SMB, you have two choices.

Choice 1.- Make sure, the Router/DHCP server is always issuing the same IP address to the PCs, (that involves having their IP person enter the MAC address of each Machine into the Router/DHCP server, that way as soon as a certain MAC address connect, it knows what IP to issue, Otherwise, the PC will receive a different IP address every time it logs on, I have a client with that issue, but they decided to go DHCP and dont want to do it.

Choice 2.- Use the Computer Name instead of the IP Address for Host, that way, it does not matter what the IP address is, it will look for the Computer Name (and that is where the DNS (Domain Name Server) comes into play) without the DNS, the machine will not know what IP address belongs to what Computer, so, if you're setting Scan to SMB (Or Scan to FTP) with Computer Names, make sure you always enter the Domain Name Server address.

If you have Static IP address, you're good, since the IP address does not change anyways

[jmaister]

yes it is on host name, and yes it does have two DNS.

Is this the same as "connection specific DNS suffix" from ipconfig?

Host name resolution generally uses the following sequence:

1. The client checks to see if the name queried is its own.

2. The client then searches a local Hosts file, a list of IP address and names stored on the local computer.

3. Domain Name System (DNS) servers are queried.
4. If the name is still not resolved, NetBIOS name resolution sequence is used
as a backup. This order can be changed by configuring the NetBIOS node

type of the client.

Most places don't have an internal DNS server, and an external DNS won't resolve a hostname on your network. SMB scanning does not need DNS.

Hostname should always be the first choice but I've found that it seems to depend on the MFP for some reason.

The only problem with the Host file (local host name resolution file) is that once the Router/DHCP issues a new IP address to a computer, then that file is useless, since the file will be pointing the to a wrong location, plus, the MFP does not have a host file itself, (unless I missed something on the training class, which could be possible) so it either looks for an IP address or looks for the DNS server, any company that has a Windows server does have a DNS server, its just not configured.

I've worked with Computers since I was on 4th grade, and Done IT since the early 90's back when NetBEUI and NetBIOS was a standard protocol as well as IPX (Old Netware), Most of the companies I've gone to both in California and in Chicago, dont even have NetBEUI and NetBIOS even installed. But then again, that's just the companies that I've worked with.

I thinks you're incorrect. All MFP's have a hostname. Scanning to the hostname is the best way to set up SMB. If the computer changes IP, the scan will still find the computer based on name rather than IP.

[jmaister]

Its scanning to a BA NS 220 not a actual computer.

With a domain name, it still doesn't work. Does the name need to be in IP form?

[tmaged]

I would try setting the IP address in the Host field for SMB scanning. Make sure the share name of the folder is correct by browsing to it from the run line. \\servername\sharename Then after that, authentication would be the only other issue. What error code are you getting ?
I've attached the scan guide in this thread. http://www.copytechnet.com/forums/ky...ndows-7-a.html

...

Its a NAS220, the permission is managed from the drive. Until I get the login and password, nothing i can do.

its probably not anything related to DNS, DN, the usual authentication.

bloody seagate...

[tmaged]

You should be able to use anyones login that has rights to write to the drive.

[jmaister]

really?

the previous machine didnt have a login, so I doubt that's the case. I need to get into the drive to verify.

AND, i'm curious to see what this $500 thing does.

According to the screenshot you provided. The Host name in the MFP is the MFP's own name, not the destination's host name, if you scan to SMB you're scanning to a Computer's Shared Folder other than the MFP, not to an MFP Shared Folder, that would be the Document Box, (which some people use as well, but that's too many steps for the user, who usually only knows the program they use for work and a very basic understanding of windows file system.)
it is possible I might be doing something wrong, but I have tried to set up scanning to the computer name, without setting up a DNS address (or telling it to use the DHCP as DNS) and 100% of the times does not find it, as soon as I enter the DNS address or tell it to use the DHCP as DNS, it works like a champ.

I was replying to the statement that the MFP does not have a host name. They do have hostnames. This allows you to print to the hostname of the MFP when it's set to DHCP. Scanning is the same way in reverse. Use a hostname when the workstation is using DHCP to allow you to find it.

i believe what he meant is find a login which is used to login into the drive, rather than login for the machine....plus if i'm not mistaken, the login in the machine is for administrator purpose only right?

plus some NAS had ftp function...check on it and make use of it

EDIT:
if it's this one you're talking about then it has a ftp function
