@george1421 said in Windows (Powershell) / Username=Computername:
If you run this PS script outside of the context of a snapin (i.e. run it locally on the target computer by hand) does it run correctly? Right now we need to isolate the issue. Is it a FOG Snapin issue vs a PS script issue.
Same thing, when I run it locally. I think, it is a Powershell/Windows-Issue
@sebastian-roth said in Changed IP of Fog, dhcpd is not starting anymore...:
/etc/default/isc-dhcp-server
That was it.
I changed it, because indeed there was the old interface in there. Now the dhcpd works fine.
I also found, that in /tftpboot/default.ipxe was the old IP-Address.
Maybe these two places are worth to be mentioned in https://wiki.fogproject.org/wiki/index.php?title=Change_FOG_Server_IP_Address
Now I have another problem, but I will open a new thread for this 
Thanx everybody for your help!

As far as I know, you cannot mount a nfs storage from a nas and reexport it, which is required by fog.
Maybe I have a snapshot before I went through the list to resync the credentials. Will check tomorrow, when I am back in the office.
