Logon Failure with Network Drive

[richs]

I am unable to map a network drive (a Buffalo Terastation) because I always get the response :"logon failure - unknown user name or bad password" whenever I respond to the Terastation-generated logon request. I have named my workgroup HIHOME and all of my three computers (two on W7 and one running Ubuntu Linux) are in this workgroup, as is the Terastation. I noted that the logon response says that I am trying to log <computer name>\<user name>, and the computer name is not HIHOME. So I tried logging on as HIHOME\<user name> and this did update the workgroup but otherwise made no difference.
I can log on to the Terastation's web page in IE8 using its IP address, and I tried mapping the drive using the IP address instead of the name, but it made no difference.
I have made sure that I have specified my network as a HOME network rather than a "public" network, and I have turned off password protected sharing in "Advanced Sharing Settings". None of this made a difference.
I can see and access the Terastation folders using the computer running Ubuntu Desktop without difficulties, and the Terastation validates the same username and password which fails on Windows 7.
Anybody have any ideas?

Turn on password protected sharing. Make sure all computers have passwords set for accounts. If you have the same user name on machines, make sure same password too.

Setting static ips and placing references to remote machines in hosts file on machine you're sitting at can go a long way to making life easy.

C:\Windows\System32\Drivers\etc\hosts

Use notepad to edit.

For example:

192.168.0.24 MYBEDROOMPC
192.168.0.25 XBOX
192.168.0.26 PS3
192.168.0.27 LIVINGROOMPC


Those are computer names on network.

Thanks, but no luck.

First, I was mapping network drive with IP address anyway, so I didn't think I needed to change the hosts file. But, when I try to, it tells me access is denied. I am the only user and I am administrator. The system will not let me "open as administrator" on this file. I turned on password protected sharing but made no difference. All computers have passwords set for their accounts. I do not have duplicate user names on machines. I'll try Help to find way to change hosts file but I don't see how this will help if I am accessing with IP address. Also, the remote server (Terastationn) responds with password request but somehow the password is garbled on the way. Something to do with encryption, I suppose.
Thanks if you or anyone else can help further.

Are you using the remote machine's login credentials as opposed to your own? If not, use the username/password that you would use when you are sitting at "other" machine, to get in.

 

[richs]

Thanks,
The "other machine" is a Buffalo Terastation. I have set up usernames and passwords for this device years back. I can access the files there fine using all of those usernames and passwords from my Linux computer, but not from the Windows 7 machine.

 

[torrentg]

Do you get some sort of failure code with that error message?

 

[richs]

When I enter the mapping information (e.g., \\192.168.1.89\photos) and click on "finish" I get a login screen after a few moments, which says "enter network password - enter password to connect to 192.168.1.89", and I enter my username on that server ("admin") and the password, and I get the message "Specified Network Password is not correct"

 

[torrentg]

Username/password might be case sensitive especially since Linux computer on network. See if this helps at all.

Also, ensure that your dns settings are correct. Sync the times for all computers.

 

[richs]

Thanks, all usernames and passwords are in lower case for just this reason. DNS settings are correct on all computers, and times and timezones are synced.
I tried again after checking and continue to get either the message "unknown user name or bad password" or "incorrect network password" depending upon whether I am just trying to access files via Windows Explorer or trying to map a network drive.
If you have any other ideas I'd be very grateful.

 

[torrentg]

Not off the top of my head, no. Best bet is to Google the errors and try to find suggestions.

 

[richs]

Thanks for your efforts. After some time fiddling with permissions I was able to add the IP addresses and computer names to the \etc\hosts file but this made no difference.

 

[richs]

Aha - after a web search I found the answer.

It was necessary to go to Administrative Tools/Local Security Policy, then select Local Policies/Security Options and then select Network Security LAN Manager authenticatioin level and then in the drop down menu in the new window select Send LM and NTLM responses. Then all worked as I wanted, and I was able to map network drives and view folders on the Terastation.

 

[torrentg]

Nice find. Glad for you.

 

[richs]

Thanks again for all your time and effort

You had to do all that to map a network drive? wow. I have a terastation too...I think I'll budget a bit more time for the install!

 

[richs]

That's not so bad, just a click or two of the mouse, once you know where to point it!

signed up just to say cheers for sharing the fix for this, came across this problem this morning. so saved me googling it

Just to note I also have a Terastation NAS, one of the old Terastation Pro's, there is an updated firmware available which will upgrade Samba to version 3.

Version 3 of Samba supports NTLMv2 authentication, thus meaning you don't need to compromise security on your Windows Vista/7 machines.
