Having used the ServiceDesk tool whilst employed by SUN for a period
years ago, I am now in need of a similar system for internal support use.

What is the actual ServiceDesk tool that is used internally at SUN? I
know it is called ServiceDesk, but is it an actual SUN product and if so, is
it solely on the Solaris platform?

If possible where can it be obtained / purchased?

Googling for Servicedesk produces no answers as it looks like every Tom
/ Dick and Harry have a product called ServiceDesk

Any help much appreciated,
