RE: Logon Issue - could someone explain please



Hello Alex,

Thank you for posting here.

According to your description, I understand that you get security event 540
on SBS. If I have misunderstood the problem, please don't hesitate to let
me know.

Based on my research, event 540 indicates that a remote user has
successfully connected from the network to a local resource on the server,
generating a token for the network user. When a user logs onto his or her
computer, Success Audit for Event ID 540 will be recorded on the Domain
Controller. When a user connects to the shared folder on the SBS server,
Success Audit for Event ID 540 will also be recorded.

I suggest we try the following steps to see if we can resolve this issue:

Method 1:
On servers having issue run the following steps
1) log on as an admin
2) from a command prompt, enter "at [time] /interactive cmd.exe", where
[time] is
some time in the near future
3) Switch to the new command prompt that launches
4) Change to c:\windows\system32\wbem
5) Execute "mofcomp scm.mof"

Method 2:
SBS 2003 creates a GPO on the Domain Controllers container named Small
Business Server Auditing Policy. Logon Events are audited for Success and
Failure by default. These events can be stopped by turning off Success
logon auditing, although it is not recommended. To do so:

1. Click Start, click Run, type "gpmc.msc" and click OK.
2. Expand Domains -> your domain -> Domain Controllers.
3. Right-click Small Business Server Auditing Policy and click Edit.
4. Expand Computer Configuration -> Windows Settings -> Security Settings
-> Local Policies -> Audit Policy.
5. In the right pane, double-click Audit logon events and clear the Success
check box. Click OK.
6. Run "gpupdate /force" on SBS.

If the issue persists, please kindly help me collect some information for
further investigation:

1. Can you ping the IP 192.168.1.49?

2. Save the security event log and system event log as evt files on the
problematic machines and send to my mailbox: v-terliu@xxxxxxxxxxxxx

3. Try to shutdown this workstation (192.168.1.49), do you still get event
540 from this workstation?

4. Try to disable the user account woodstock, do you still get event 540
from this user access?

Hope this helps.

Please feel free to let me know if you have any questions or if you need
further assistance.

Best regards,

Terence Liu(MSFT)
