For community benefit, here are the ports that NMAP appears to use for OS Fingerprinting when called by LANDesk UDD. I obtained these ports from the XML output file generated by NMAP during UDD/Fingerprinting, and cross referenced ports on the IANA database and supplemented "unknowns" from the list maintained by PC-LIBRARY.COM
Also, here's the exact parameters that LANDesk calls NMAP with:
NMAP.EXE -v -PN --min-hostgroup 128 --max-hostgroup 512 -T4 -sS -F -O -iL <LANDesk generated list of IP addresses to scan> -oX <XML output>
-v increased verbosity
-PN Treat all hosts as online (scan ports even if no ICMP response)
-T4 Timing template 4
-sS SYN scan technique
-F Fast mode (fewer ports - limit to the 100 most common ports listed below)
-O Enable OS detection
