what does this 'IS~' prefix mean (when pinging)?

[Guest]

hello

i am just wondering if the experts in this group know what this 'IS~' prefix actually mean. i was trouble shooting for an issue where no client could "termainl service" to the host machine. and when I tried to ping it e.g
ping -a 127.0.0.
I got a funny machine name back e.g
Pinging IS~MACHINENAME [127.0.0.1] with 32 bytes of data

Reply from 127.0.0.1: bytes=32 time<1ms TTL=12
Reply from 127.0.0.1: bytes=32 time<1ms TTL=12
Reply from 127.0.0.1: bytes=32 time<1ms TTL=12
...

* The thing is that the 'IS~' was never there before. And after I restart the machine, the 'IS~' prefix also disappeared. I am really curious to find out what that thing is. Please share your knowledg

Thanks

Thanks for your reply Netwerks

However, I am not convinced. with the experience I had, that the 'IS~' only appeared when my users couldn't logon to my terminal server machine, and not after I rebooted the system. Also, why would it show 'IS~' but not 'IIS~'??

Please help (including all the experts over there. I am sure it will benefit others in this newsgroup!

Thanks. on

I think the following two articles may help you understand.

NBLookup.exe Command-Line Tool

Better yet (maybe):
