New Post: When I send "Detect Now" I get "Error" as result

Hello Norbert,

Ping hostname give the same IP as the entry in the field of the WPP (IP Adress). In WPP this field is orange highlighted. Flushing the DNS cache didn't chance the result. Restarting WPP and the WSUS Server didn't change the result.

The IP Adress is the same as the client has.

Update:
If i ping the hostname (ping ABC) i've got a result like "xxx.xxx.xxx.xxx bytes time ttl". If i ping the FQDN (ping abc.blahblah.blah) i've got an error msg (ping can't find Host, try again).

Trying the same with a client wich is green highlighted in WPP (IP Adress), i get the normal result (IP BYTES TIME TTL).
