Best Practices Report indicates "The pointer (PTR) resource record of IP address 10.0.0.3 is incorrectly set to PWA-dc01. It should be set to PWA-DC01.pwa.local"

How can I correct this?

Go into DNS and expand your server, expand reverse lookup zones and double click the PTR record for 10.0.0.3. In the "Host name" box, just add the pwa.local to the name and hit okay. That should take care of it.

Thanks you acbrown.  The Host Name is  already correctly identified there (but in lower case letters).  If I change it to the format PWA-DC01.pwa.local  and Apply it it appears to accept the change but it doesn't in reality.  next time I open it it has regressed to the lower case spelling and the Best Practices Analyzer still identifies the PTR as incorrectly set.  From Googling the problem I believe it has something to do with the fact that SBS wont allow you to modify the configuration except through a specially designed SBS route.  Trouble is I can't discover what that route is.

Let me run some tests on my own SBS test VM to get some more information for you.

You can't change this record per se.   PWA-dc01 is the host name.  The name you gave to your SBS Server.  If you go to Computer > right click > Properties on the SBS server you will see the computer name is PWA-dc01.   Its what you named the server during setup and you can't change this without a reinstall.

On the properties of the network card, select TCP/IP and then properties, click advanced and then under the DNS tab at the bottom of the screen do you have a DNS Suffix specified?

If not enter your internal domain name and check the box to use this in DNS registration.

Then restart the netkohon service.

Cris is right you cannot change the computer name in SBS and you also cannot change the DNS name in computer properties either.
