Cannot connect to CIFS share through Windows Server 2008 R2

We have recently upgraded some server to Windows Server 2008 R2. But once we did this we can no longer access shares on a ReadyNas NV+. We can connect to this share from any 2003 server, xp, or Windows 7 client. Also we can connect with a Server 2008 box only after entering in the credentials

user.name@domain.local

Firewalls are completely off and I can ping the device from the Server 2008 R2 boxes. I just cannot connect to it.

Also If I use a ip to connect to the server it does prompt me for credentials, but it will not accept any that I give.

Also I can restart the server and can access the shares. But this goes away after time. Almost seems liek it's a bug in the OS itself.

Maybe a didn't categorize this correctly?

Most-likely the CIFS share you are trying to access doesn't meet the security posture, being exhibited by Windows Server 2008. WS08R2 offers a significant change in how server shares are handled and accessed.

I am leaning towards this myself. I have looked around for other answers any I see alot of issue involving nas devices and server 2008 and R2 version.

The device I am having issues with is a ReadyNas NV+

I also want to add that when we reboot these server, they can then connect to the CIFS share. But after some time we cannot conenct to the shares.

How are the clients accessing the ReadyNAS normally? Can this device be joined to an Active Directory domain?

Author

Commented:
The device is joned to the domain, and has been for about a year now with no issues.

We use this mainly for a backup location.

Sometimes I can get the 08 R2 box to connect by accessing the ip of the box, but then I have to use my cententials in a username@domain.local format. After this it sees the shares but access one of the folders then asks for a network password, which then does not accept the login.

It sounds that the drive's on the NAS are not formatted with NTFS, which is why you have to authenticate at each folder. The access by IP and not by hostname eeks of a DNS problem. Is there a hostname for the NAS in DNS?

Author

Commented:
you are correct. The drives are formatted in ext3. But this happens only on Server 2008 R2. I do not get prompted like this on any other system. Any opther system I can simply browse tot he shares and my credentials are passed.

DNS does have a record for the nas device.

You may have to install the files services for Unix role on the server. This will make it so Windows has the necessary awareness to access sure file systems, consistently.

tried that but it's a no go.


Something is working and then not working in the OS


If I reboot the server it works jsut like any other machine. But after some time it quits working.

If you can nail down a time, you could match that with the System/Security/Application log in the Event Viewer. ~ or ~ Observe a set of consistent conditions which cause the server to lose a connection.
Commented:
The problem was multiple connection witht he same user account. After so many time the machine accually locked the connection till a reboot.
