You can use one or more of the following methods: - Method 1: Using Windows NT Auditing. -or- - Method 2: Using Microsoft Network Monitor (or other network tracing utility) -or- - Method 3: Using Windows NT Diagnostics (NT 4.0) 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: a. If possible, include only the primary domain controller or backup domain controller that is most likely to validate the user. b. Set a capture filter, including only the server message block (SMB) protocol. c. 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" (without the quotation marks) 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 Additional query words: ====================================================================== Keywords : kbnetwork kbClient kbRemote kbSecurity kbServer kbsms200 kbsms120 kbAudit kbNetMon kbNetTrace kbsmsUtil kbRemoteProg Technology : kbSMSSearch kbSMS120 kbSMS200 Version : :1.2,2.0 Issue type : kbinfo ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
