Scanning once you are on the LAN can pose a problem. Nmap requires installing pcap and usually an interactive install (metacab is an option depending on scope) and some AV's will flag on those types of things (which is understandable). Since there is no native scanning capability in windows you are forced to either install something or upload a standalone binary. Foundstone's scanline is one option but its not one of my favorites. You can write your own and upload that but I'd hate to have some custom code submitted to some AV vendor by some motivated admin. Or you can upload Microsoft's portqry.
C:\>portqry -n server1.company.com -e 3389
Querying target system called:
server1.company.com
Attempting to resolve name to IP address...
Name resolved to 10.1.1.1
querying...
TCP port 3389 (unknown service): LISTENING
Checking out the KB article on portqry will give you some of its more useful features.
Some fun options are its ability to send default ldap queries:
portqry -n myserver -p udp -e 389
UDP port 389 (unknown service): LISTENING or FILTERED
Sending LDAP query to UDP port 389...
LDAP query response:

======== End of LDAP query response ========
UDP port 389 is LISTENING
and "sqlpings"
portqry -n 192.168.1.20 -e 1434 -p udp
You receive the following output:
Querying target system called:
192.168.1.20
querying...
UDP port 1434 (ms-sql-m service): LISTENING or FILTERED
Sending SQL Server query to UDP port 1434...
Server's response:

IsClustered No
Version 8.00.194
tcp 1433
np \\SQL-Server1\pipe\sql\query
==== End of SQL Server query response ====
UDP port 1434 is LISTENING
It also does snmp queries and ISA queries and evidently RPC end-point mapping as well.
There are other fun features and the localhost options are worth looking into as well.
Some of the not so fun stuff. No randomizing ports. You can do an ordered list or ranges but no random. ONLY ONE HOST AT A TIME :-( but that's what batch files are for.
If anyone else is using this for pentests please let me know your thoughts.
