I have Server1 on a domain. This server is the one with GFI installed on it. Then I have Server2 and Server3 in a DMZ. My problem is I have a scans setup for both server 2,3 and Server3 seems to work fine but, Server2 is filling the Eventsmanager with tons of Failure Audits. Here is the error im getting....

Event Origin Details:
   Date:        8/19/2008
   Time:        8:28:25 AM
   Type:        Failure Audit
   Username:    NT AUTHORITY\SYSTEM
   Computer:    Server2
   Source:        Security
   Category:        Logon/Logoff
   Event ID:        529
   Internal Event ID:    28D19A8B15
   Rule Name:    Logon failure - unknown user name or bad password - outside work hours
   In Work Hours:    No

Logon Failure:
   Reason:        Unknown user name or bad password
   User Name:    LNSS_MONITOR_USR
   Domain:        Domain
   Logon Type:    3
   Logon Process:    NtLmSsp
   Authentication Package:    NTLM
   Workstation Name:    Server1
   Caller User Name:    -
   Caller Domain:    -
   Caller Logon ID:    -
   Caller Process ID:    -
   Transited Services:    -
   Source Network Address:    192.168.0.0
   Source Port:    0

More information:
User LNSS_MONITOR_USR from domain Domain tried to logon (Type 3) from the machine Server1 to the machine Server2 and specified either a bad username or bad password.

All servers on the domain have the LNSS_MONITOR_USR installed on them but the ones in the DMZ do not. Is this why I am getting the Failure Audits?


Thanks For The Help!!!

Hiya,

You might have to create a different scanning profile for your machines in the DMZ. I guess you are scanning under Domain admin credentials, so these will not work. There might be a mechanism that will make the NSS Scan fall back on trying the LNSS_MONITOR_USER account, which does not exist on the machines in the DMZ.

Try to create a separate scanning profile and giving that profile valid credentials for those two machines.

Alternatively, you can always tell EVM to ignore these events.

Take a look into the services.msc. Is the LNSS Service running under the LNSS_MONITOR_USER account? If that's the case, then I think NSS will always first attempt to run a scan under its own credentials and if that fails, it will take the credentials given in the scannng profile. Even if you cahnge it to something else, it will always raise the error on the target machine.

Creating the LNSS_MONITOR_USER  on the target machine would also not work becasue I believe the service would be running under Domain\LNSS_MONITOR_USER, and that you can not create on the target machine.

I don't know if there is a way to force NSS to use the credentials given in the profile first. Might be a perculiarity of NSS. If this is all correct, then I'm afraid you have no choice but to tell Eventsmanager to ignore the event.

Spider,

I had to change the User Account that the Service for all GFI Products were running under to an account that I created with Admin rights. I do not see the Failure Audits on any new scans. Yippee.....

But....

I still have issues with DELL Open Manage telling me that packets are being lost on the two servers in the DMZ. It only seems to happen when the Scans are going on either one of the two servers. I have my scans set for 3 am and getting an email on my phone from DELL Open Manage is not cool that early in the morning...

Any Suggestions...????

Thanks For The Help!!!

Travis

Packet loss can be attributed to a lot of factors.  Do you get these messages if the scans occur manually during the day? We may need to look into WireShark a free packet logging utility so we can better understand what is happening.
