Work Group Manager slow and authentication oddness

Hello,

I have install Snow Leopard Server 10.6.3 but am having some authentication issues.

1. When I log into Workgroup Manager is takes about 1 or 2 minutes before the accounts appear. Forward and reverse DNS are working.
macmini:~ admin$ dig +short macmini.local
10.1.1.5
macmini:~ admin$ dig +short -x 10.1.1.5
macmini.local.

My hostname seems to be fine as well.
macmini:~ admin$ sudo changeip -checkhostname

Primary address = 10.1.1.5

Current HostName = macmini.local
DNS HostName = macmini.local

The names match. There is nothing to change.
dirserv:success = “success”

2. If I ssh or ftp in to the server things are quite slow to authenticate.
3. I can no longer log in from my laptop by clicking on (Share Screen) from Finder, I get an authentication failed BUT if I go to the screen sharing app directly and try to connect by IP it works. My laptop also has working forward and reverse dns.

There are no obvious errors on the Console or the Server Admin log viewer. I was hoping to find a timeout message or something similar but no luck.

I am about to go back to Leopard server if I can’t get this working soon. I suspect if I can fix one problem I will fix the other too.

Any ideas?

Cheers.
