Fixing db_nmap misidentified operating systems inside the metasploit host database

I was doing some scanning the other day against my test lab of VM’s. I noticed that nmap and db_nmap were seeing my windows XP machine as Server 2003. Nmap identified its OS details: Microsoft Windows XP Professional SP2 or Windows Server 2003. When it’s placed inside of the metasploit db, it has the os_flavor 2003. This could be a problem depending on resource scripts or when you attempt to use an exploit against the box.

135/tcp  open  msrpc         Microsoft Windows RPC
139/tcp  open  netbios-ssn
443/tcp  open  https?
|_ssl-cert: ERROR
445/tcp  open  microsoft-ds  Microsoft Windows XP microsoft-ds <=========
1027/tcp open  msrpc         Microsoft Windows RPC
1433/tcp open  ms-sql-s      Microsoft SQL Server 2005 9.00.1399.00; RTM
3389/tcp open  microsoft-rdp Microsoft Terminal Service
MAC Address: 00:0C:29:91:D5:28 (VMware)

The scan shows 445/tcp and clearly says XP.
Here is that same machine’s info inside the database.

msf > hosts

Now the question is how do we fix this?
Start msfconsole and type irb.

msf > irb
[*] Starting IRB shell...


Now type:

host = framework.db.workspace.hosts.find_by_address("")

Change to the IP address of the host you are trying to modify.
Now run the hosts command and see that the flavor is corrected.
