Assuming you accepted most defaults during setup, and are on the same network it should just work.
Tell us what you did during install.
Okay, I can get in to the admin directly on the test server terminal itself and the reconfigure dialog matches the install dialog so here is what I did.
Primary Domain: test.local
System Name: sme
Local Network Device: selected only existing ethernet port
Local IP Address: 10.0.3.234
Subnet Mask: 255.255.255.0
Mode: Server Only
Gateway: 10.0.3.1
DHCP: Off Do NOT provide (since gateway does that)
DNS Server: 10.0.3.1 (changed to this since leaving it blank failed to provide internet access)
One thing I did do before trying to access the new server manager from the browser of another computer on the local network was install the PHPMyAdmin and WebHosting contributions since I need those two to actually make the test server useful. Do you think one of those could have caused the problem I'm having. Based on your reply I'm guessing that I would still access the new smanager by using
http://10.0.3.234/server-manager in my browser like I did under SME10.
One other thing I should mention. I just tried to connect to the text mode server manager you are supposed to be able to access when you log in directly on the server itself as admin (menu item 6. Access server manager). When I told it Yes I wished to proceed I got the following error message:
Unable to retrieve
http://localhost/server-manager: Connection refused
