I have a new PC (PCIex, Celeron 2.8GHz, 512MB, 40GB)
reconfiguring hangs at the end until I reset
(I have done a fresh install of SME7rc2).
reboot does not work - even at the command line
nor does 
shutdown -h nowany ideas?  SME7rc2 cofigured as follows...
Server Mode   serveronly
Local IP address / subnet mask   192.168.99.2/255.255.255.0
Gateway   192.168.99.199
Additional local networks   192.168.99.0/255.255.255.0
DHCP server   disabled
Server names
DNS server   192.168.99.2
Web server   
www.tyrex.com.auProxy server   proxy.tyrex.com.au:3128
FTP server   ftp.tyrex.com.au
SMTP, POP, and IMAP mail servers   mail.tyrex.com.au
Domain information
Primary domain   tyrex.com.au
Virtual domains   tyrex.com.au
Primary web site   
http://www.tyrex.com.auServer manager   
https://dfemail/server-manager/User password panel   
https://dfemail/user-password/Email Addresses   useraccount@tyrex.com.au
firstname.lastname@tyrex.com.au
firstname_lastname@tyrex.com.au
ps also browser access to the server-manager seems very slow 
(typically 10-30 seconds), and mailsettings do not 'stay' in place,
although I can add an ibay.
TIA Rob
