Raptor34
Hi.
I receiece alot of this meesages from my intrusion protection system on asl 5.202.

[1:2924:0] A NETBIOS SMB-DS repeated logon failure [Classification: Unsuccessful User Privilege Gain] [Priority: 1]:  {PROTO006}

The ip is from my webserver on dmz and to a computer on my lan.

What is this? anyone..

    this means that your ips has realized an logon attamp from your dmz pc to your lan pc.
    you have to fine tune your ips settings (exclusions, etc.).
    also take in mind that there are a lot of false positives. so it takes a while till ips is configured well.
    also check whether you really need smb from dmz to your lan.

    thx for answer
    there is no traffic allowed from dmz to lan.
    but i think maybe this is related to som logging software on webserver....

    I will investigate furter[:)]

    Remeber to consider disabling administrative share on dmz if not necessary other than limit ms protocol (smb,445,134 an other...).
