Hi All I had a question regarding netbios rules. Lately I have been receiving a lot of the alerts as shown below where A.A.A.A and B.B.B.B are all internal hosts to my network. In addition B.B.B.B is the IP address of our domain controller. Is this merely false positiive or something i should be concerned about. How do I go abt troubleshooting further to see what exactly is happenig. Any help will be appreciated Thanks Ravi [**] [1:2466:4] NETBIOS SMB-DS IPC$ share unicode access [**] [Classification: Generic Protocol Command Decode] [Priority: 3] 11/30-14:05:00.173386 A.A.A.A:1105 -> B.B.B.B:139 TCP TTL:128 TOS:0x0 ID:22636 IpLen:20 DgmLen:128 DF ***AP*** Seq: 0xD1482D9A Ack: 0x4A54B89D Win: 0xFFFF TcpLen: 20 [**] [1:2404:5] NETBIOS SMB-DS Session Setup AndX request unicode username overflow attempt [**] [Classification: Attempted Administrator Privilege Gain] [Priority: 1] 11/30-14:05:00.163386 A.A.A.A:1105 -> B.B.B.B:445 TCP TTL:128 TOS:0x0 ID:22635 IpLen:20 DgmLen:1440 DF ***AP*** Seq: 0xD1482822 Ack: 0x4A54B769 Win: 0xFAB7 TcpLen: 20 [Xref => http://www.eeye.com/html/research/advisories/ad20040226.html][Xref => http://www.securityfocus.com/bid/9752] The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
