This is odd.

OES2 SP1 server (fully patched)

It's setup as a DA (itself), so it points to itself (not on the loopback IP, but on the "regular" IP).

I've noticed that randomly it seems to stop showing itself as a DA.

So I do:

slptool findsrvs:service

It will show itself

Then random time period later, I'll do the same command and it no longer shows it's own IP. In fact, it'll show nothing

but the slpd is running

After another random time period later, I run the same command and then it shows itself back up okay.
