Hi,
I have a IP address of the target machine.Is there is any way to find out whether it is a unix box or windows box without logging into it?.

Why do you need to do this? Can't you ask the admins?

GFI LANguard Network Security Scanner can do this: http://www.gfi.com/lannetscan/

If you not authorized to scan the network, this could cost your job.

In the current scenario,I cannot ask the admins.I dont have provision to
buy any new software.I got the answer from one of my colleagues which
is as follows:
when we execute the ping command,if the TTL is 32 bytes ,then windows or if the TTL is 64 bytes then it is unix".
But I don't know how far the above conclusion is correct?

TTL is Time To Live for multicast packets and shows how far a packet can be transmitted (from 0 same host, 1 same subnet, 32 same site, 64 same region, 128 same continent, 255 unrestricted)
Do you mean Packet size? For the UNIXes I've used recently this defaults to 64 and for windows 32 - but this is controlled by the system sending the 'ping', not the remote machine, so doesn't help you.

The only sensible solution seems to be to ask the people who know - the sys admins.

hello,

how about nmap??
