Problems accessing shares via IP Address only

Did you add a share to the IP name?  If not, it may be trying to access C$ which will require a password.

Here is the detail John.

Server1 - 192.168.1.20
Server2 - 192.168.1.21
Server3 - 192.168.1.22
Server4 - 192.168.1.23
Server5 - 192.168.1.24
Server6 - 192.168.1.25
Server7 - 192.168.1.26
Server8 - 192.168.1.27

When i Go to Server8 and Open Run and Type
"\\Server1"(No Folders after the server name nor "\") to 8, it opens
When i Type the IP of Server1 and Server 2 like "\\192.168.1.20" and 21, it opens.
However, all other IPs are prompting for Username/Password and it says "Logon Error: Unknown Username or Bad Password"

Now

I went to Server4 and Open the RUN and type:
"\\Server1"(No Folders after the server name nor "\") to 8, it opens
When i Type the IP of Server1, 2, 3 and 8 like "\\192.168.1.20" 21, 22, and 27 it opens.
However, all other IPs are prompting for Username/Password and it says "Logon Error: Unknown Username or Bad Password"


Not sure what you are trying to point as "Share to the IP Name"

The security seems to vary a bit by server and with NO folder share (just Server) the server will interpret the request as C$ (or D$ whatever) and insist on a password. So what you see is normal so far as I can see.

@Vicky This sounds like cached credentials issue. You can cache the credentials for network shares that are tied to either hostname or IP address. You can manager your credentials in the Windows Credential Manager.

Mapped drives can also have this effect or having other network connections established to the server already. To check if you have connections established you can run net use with no parameters and it will show you all your connections. You can then use net use again to delete any connections if necessary and then try connecting to the share again.

My guess though is the cached credentials.

@John,
I agree, but the problem here is that

Even if i try "\\<IP Address>\<FolderName>" still it is the same.
Asking for the credentials and throws an error.


@Jeremy,
I have already tried Net Use command and it shows about only one server. nothing else.

Also,
here is what i did and found.
Logged into Server4 and server8
Tried Accessing the "\\<IP Address of Server4>" from SERVER8
Tried Accessing the "\\<IP Address of Server8>" from SERVER4

Found that the moment it fails to authenticate me, it generates an event in security log:

This event is generated when a logon request fails. It is generated on the computer where access was attempted.

The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).

The Process Information fields indicate which account and process on the system requested the logon.

The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The authentication information fields provide detailed information about this specific logon request.
      - Transited services indicate which intermediate services have participated in this logon request.
      - Package name indicates which sub-protocol was used among the NTLM protocols.
      - Key length indicates the length of the generated session key. This will be 0 if no session key was requested.

Understood. But have you checked the Credential Manager? Clear out any cached for the servers you're try to connect to.

@Jeremy

Yes, nothing is there too.

Also, just saw a strange thing on the server. i downloaded psGetSid on SERVER8, and found following:

Are all server running the same service packs / hotfixes?

@compdigit44

Yes.. All are running same.

Looks like you have a lot of duplicate SIDs on your network. All of these servers have the same SID:
SID for \\SERVER1:
SID for \\SERVER2:
SID for \\SERVER3:
SID for \\SERVER4:
SID for \\SERVER5:
SID for \\SERVER6:
SID for \\SERVER7:
S-1-5-21-1284242540-3484221295-1895800360

This is only a problem if they're domain controllers.
Are any of these domain controllers?

@Jeremy,

Yes, SERVER1 and SERVER2 are DC.

@Jeremy,

I need to check from with my Old SysAdmin that "was server 1 or 2 used to create the domain?" or not?

For now till i find the info, if i assume that server1 or server2 was used t create a Domain, than according to your recommendation, we need to run Sysprep on all rest of the servers (server3 to Server7).

If i do that, i am just concerned about the roles installed on the server. As, one of them are Print server, one of them are DFS, one of them are WSUS, one of them are APP. Does, running sysprep would remove those roles and do we need to configure again everything?

Also, what if i just run the ChangeSID from Sysprep?, will that work and keep the server roles intact ?

Since, Server1 and 2 are DC. so, afaik, They both should be having the same SID. right?

Rest on the servers, i will check what needs to be done and update here if i run into the issue.
