TCP 41524 is a documented broadcast port for ArcServe (for license
validation); given the close proximity and the presence of 6050 could the
41523 be an undocumented port for ArcServe?

Hi All,

Whilst doing a pen-test I came across a Windows NT4 box with IIS4. After
doing a port scan, I noticed, among others, that port 41523 was open.

Using Amap, the result returned is unknown, however the data given is:

Response received from xxx.xxx.xxx.xxx port 41523 tcp (length 8 bytes):
0000: 424e 4532 3937 4400
ASCII: "NETBIOS_HOSTNAME" <= I've replaced the real hostname
Unidentified ports: 41523/tcp (total 1).

I've searched google without any luck. Does anyone know what this may
be? I don't have access to the machine to run fport.exe or similar.
Below is the results of an Nmap, if it helps.

ort State Service
21/tcp open ftp
22/tcp open ssh
80/tcp open http
81/tcp open hosts2-ns
88/tcp open kerberos-sec
135/tcp open loc-srv
139/tcp open netbios-ssn
443/tcp open https
1027/tcp open IIS
1038/tcp open unknown
1041/tcp open unknown
1433/tcp open ms-sql-s
4899/tcp open radmin
6050/tcp open arcserve
8314/tcp open unknown
41523/tcp open unknown

Thanks,

-Patrick
