Share Folder Access Problem

Hi,

We are facing the issue with NAS storage access. We have a NAS storage which have got some shared folders. Users access the folders from their PC's. We are facing the issue that when we try to access the share with IP\\192.168.1.1 it gives error that the "attached device is not functioning" but when we try to access as\\servername it works fine.

I have taken netmon trace while accessing the drive as IP and as Hostname and some of the highlights are as follows:

-------------------------------------------------------------------------------------------------------------------------

When accessing through IP

1. Client -> Server: SMB: C Negotiate, Dialect = PC NETWORK PROGRAM 1.0, LANMAN1.0, Windows for Workgroups 3.1a, LM1.2X002, LANMAN2.1, NT LM 0.12, SMB 2.002, SMB 2.???

2. Server -> Client: SMB: R negotiate, NT LM 0.12 # = 5

3. Client -> Server: SMB: C session setup & X, NTLM NEGOTIATE MESSAGE

4. Server -> Client: SMB: R session setup & X, NTLM Challenge message error code 22 Status More processing required

5. Client -> Server: SMB: C session setup & X, NTLM Authenticate Message Version:V2 Domain:domain, user:username,workstation:PC1

6. Server -> Client: SMB: R session setup & X NT Status: System Error Code 563 Status DOMAIN Controller NOT FOUND

After that it again goes back to point 3 and continues like that

When Access through Hostname

1. Client -> Server: SMB: C Negotiate, Dialect = PC NETWORK PROGRAM 1.0, LANMAN1.0, Windows for Workgroups 3.1a, LM1.2X002, LANMAN2.1, NT LM 0.12, SMB 2.002, SMB 2.???

2. Server -> Client: SMB: R negotiate, NT LM 0.12 # = 5

3. Client -> Server: SMB: C session setup & X,Krb5ApReq(0x100)

4. Server -> Client: SMB: C session setup & X,Krb5ApReq(0x200)

5. Client -> Server: Tree Connect Andx Path: \\hostname

The domain Controller which is there in that site is Windows 2008 R2.
