samba - Nov 2003 - XP machines show very long server name

I ran the command "smbclient -d9 -L server > junklog" and then
searched
the junklog file. I found this line:

Domain=[NCIPRECAST] OS=[Unix] Server=[Samba 2.2.7-security-rollup-fix]

which shows the the very long server name/description. WinXP machines 
show that whole thing in Windows Explorer. Very annoying. How do I 
shorten that?
