I just installed NSM 4.0 for AD on a brand new test server Windows
2012R2. The Engine, Event and Agent servers are all on the W2012R2.
I also installed 1 SQL Express DB on the same W2012R2. (I took sql as
recommended in documentation.)
All seems OK.
I installed NSMAdmin on W2012R2.

I can't connect ! I used different users (all member of the nsmadmins
group). I always have the message : Unable to service the request at
this time.

What can I do now? Thank's in advance for the help.
