This morning none of our computers could connect to our brand new sbs 2003 server. I went onto the sbs server and it was ok, no bluescreens or error messages; however, when I right clicked on the network adapter and went to properties I noticed it had received a bunch of packets but sent was 0. On all of our client computers we could not ping the server. I litterally didn't do anything but reboot the server and we were all back up and running. The server is running a realtek PCI gigabit ethernet card. The switch was working well. I am just very confused as to what coudl be causing this. The only thing in the adapter that I subsequently turned off was "allow this computer to turn of this device to save power". Not sure if that was what is the cause but will have to wait and see. It is just a pain to have to every morning reboot the computers or the server. The only messages in my event log that I am getting are as follows:
Event Type: Warning

The DHCP service has detected that it is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service. This is not a recommended security configuration. Credentials for Dynamic DNS registrations may be configured using the command line "netsh dhcp server set dnscredentials" or via the DHCP Administrative tool.

Description:
DNS server has updated its own host (A) records. In order to ensure that its DS-integrated peer DNS servers are able to replicate with this server, an attempt was made to update them with the new records through dynamic update. An error was encountered during this update, the record data is the error code.
If this DNS server does not have any DS-integrated peers, then this error
should be ignored.
If this DNS server's Active Directory replication partners do not have the correct IP address(es) for this server, they will be unable to replicate with it.
To ensure proper replication:
1) Find this server's Active Directory replication partners that run the DNS server.
2) Open DnsManager and connect in turn to each of the replication partners.
3) On each server, check the host (A record) registration for THIS server.
4) Delete any A records that do NOT correspond to IP addresses of this server.
5) If there are no A records for this server, add at least one A record corresponding to an address on this server, that the replication partner can contact. (In other words, if there multiple IP addresses for this DNS server, add at least one that is on the same network as the Active Directory DNS server you are updating.)
6) Note, that is not necessary to update EVERY replication partner. It is only necessary that the records are fixed up on enough replication partners so that every server that replicates with this server will receive (through replication) the new data.

I did notice that at one point my ip address was changed during the new server setup from 192.168.3.x to 10.0.0.x and that some old records in dns are still there. Is there a way to completely reset the dns server in sbs to default?
