I hate to give away professional secrets here, but I frequently use
Google to give me an idea of what might be running on an unidentified
port:
http://www.google.com/search?q=TCP+41523

Looks like more arcserve to me...

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
