The problem i am facing occur on all my new 6 servers

Are they VMs?
No, physical machines.

You can reduce the initial sync time from ~ 5 minutes to ~15-20 seconds
by appending 'iburst' to your server lines.
I will try that.

There is a signifiant diference in offsets between those remote time
servers. And the jitter is quite high. Are all of these server on the
same LAN? Are any at remote sites or reached over a VPN?
No they are not reacable over a VPN. They are routed through the network
(quite complicated; but there is no WAN part inbetween).
I dont know much about the windows servers. The customer told me i can
use them for time synchronization - so i did it because the network i
highly protected from the outside lan.

The root dispersion suggests that this peer has not been synced to a
real time source is quite a while. This needs to be fixed first.
Could you please post the solaris-server 'ntpq -p' billboard from (in a
condensed format as shown above)?
This is from the solaris box:
