SMS: How to Determine Which Logon Server Was Used During Network Logon Operation (199472)

MORE INFORMATION

Method 1: Using Windows NT Auditing

To use Windows NT auditing to determine which workstation a user accessed to logon to the domain, follow these steps:

1. Start User Manager for Domains.
2. Click Audit from the Policies menu.
3. Click to enable Success for the Logon and Logoff category. Optionally, you may also check the Failure box.

After the above procedure has been implemented, Windows NT will create an event log for each successful logon attempt. The log will appear like the following example:

   Event Detail
   Date:     06/04/98  Event ID:  528
   Time:     10:06:43 AM  Source:  Security
   User:     msolanki  Type:  Success Audit
   Computer: SMSCENT  Category: Logon/Logoff

   Description:
   Logon/Logoff: Successful
   Logon User Name: msolanki
   Domain: SATHYA
   Logon ID: (0x0, 0x2D0D0)
   Logon Type: 3
   Logon Process: User32 Authentication Pkg:
   MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
   Workstation Name: \\JAMES
				

Method 2: Using Network Monitor

To use Network Monitor to determine which workstation a user accessed to log on to the domain, follow these steps:

1. Capture all incoming traffic to the domain controller(s). In order to reduce the size of the captured data, follow these steps:
   1. If possible, include only the primary domain controller or backup domain controller that is most likely to validate the user.
   2. Set a capture filter, including only the server message block (SMB) protocol.
   3. Configure a large enough memory buffer through the Buffer Settings option on the Capture menu.
2. After the data has been captured, set a display filter to only include:

      Protocol: SMB
      Property: Account Name
      Relation: Exists
   					

This will display all the initial SMB session setup containing the user name and the source media access control address.

For example:

Src Mac Addr: Dst Mac Addr: Description
WKS1          SUNKING       C session setup & X, Username = MariaH, and C
tree connect & X, Share = \\SUNKING\IPC$
WKS2          SUNKING       C session setup & X, Username = JoeSmith, and C
tree connect & X, Share = \\SUNKING\IPC$
WKS3          SUNKING       C session setup & X, Username = Administrator,
and C tree connect & X, Share = \\SUNKING\IPC$
				

In the example above, WKS1 is the computer where the user is logging on from, SUNKING is the domain controller authenticating the request, and the Description contains the Windows NT domain account being used.

NOTE: The Src Mac Addr may also been shown as a media access control or IP address if the NetBIOS name could not be resolved or the entry is not in the Network Monitor address database.

Method 3: Using Windows NT Diagnostics

To use Windows NT diagnostics to determine which workstation a user accessed to log on to the domain, follow these steps:

1. At the client workstation, click Start, type Winmsd in the Open box, and then click OK.
2. On the Network tab, click the General button.
   
   You will see information similar to the following:

Identifier            Value

Your Access level     Admin; Local
Workgroup or Domain   SATHYA
Network version       4.0
Lan Root              SATHYA
Logged On Users         1
Current User (1)      MSolanki
Logged Domain         SATHYA
Logon Server          SMSCENT
