We dont mind crappy english...
At least not me, I'm the same, lots of typos. You will learn it, the more you type it. ;-)

Shows exact the same, but not solution.

Looks like a left over from an other DC.

Try to find : a45ce9be-c350-4429-964b-a10c1dd92af5._msdcs.m2r.local 
And check what that is, any old server, a running one?
