Yesterday we tried to upgrade our F760 filer running 6.0.1r3 to 6.1.2r3. After the upgrade our NFS environment worked fine but cifs environment would not work. I can go to filer view and everything looked fine, I can see my shares, qtree and snapshots fine. All configurations as far as domain, DNS server, WINS and other networking is also fine. Yet when I try to access a share it will ask me for a login name and password. Same behavior when I try to access filer through network neighborhood even though I am logged in as administrator.

 

 

We have a windows 2000 domain and a Windows NT 4.0 domain and there is a two way trust between them. Filer is in Windows 2000 domain and it was there even before the upgrade and been working fine. Talked to NetApp support and they made me try different things but could not be able to solve the issue. According to them they have never seen this kind of problem before. After the upgrade when it did not work I ran the cifs setup it gave me an error:

 

 

"DNS does not appear to be configured correctly for proper windows 2000 operation in this domain. The filer could not resolve simple domain name 'MESIROWFINANCIA' to DNS form 'MESIROWFINANCIAL.NET'

 

If I use a filer view setup wizard it would give me an error that domain name is illegal. What is confusing here is filer had been working fine for over two years in the same w2k domain with the same name without any problem.

 

Netapp tech support had me run setup quite a few times and I also came across an error CIFS - Domain name not legal in the root volume language.

 

After trying to fix this problem for 5 hours I finally decided to roll back so that filer is up and functioning. Once I rolled back to 6.0.1r3 cifs started to work but now NFS works fine, access from NT 4.0 domain works fine but if you are logged in to windows 2000 domain you cannot access the filer even though filer is also in windows 2000 domain. When you try to access it will give you an error "The account is not authorized to log in from this station".

 

The case is still open with Netapp and we are trying different things but so far no luck. Any suggestion and help from you guys will be highly appreciated.
