Have you ever created a SMS tool that passes the NetBios name but realize that sometimes it doesn't work. Test after test shows the Netbios name not working.
"CommandLine"="wscript.exe \"c:\\Program Files\\xxx " ##SUB:NetBIOSName## "
If your right clicking on a query and it fails then you have a SMS_G_System in your query. You can only have items from SMS_R_System. Anything else and for some reason SMS can no longer pass the netbios name...
