DNS Again.... 1

[NYR]

Another DNS delima,

I have a W2K server, also running as a DNS server, Netdiag checks out clean, no errors in Event log on server. But, on the W2K professional desktops, if I don't enter the preferred DNS server in the NIC I get this error:

Event ID:1000, Userenv, Description;
Windows cannot determine the user or computer name.

Now Microsoft tells me that if I enter this info into the NIC preferred server it will "resolve" this...which it does.
My question is, have all you other Admins had to enter PDNS on all users desktops NICs or have I got something wrong??
I have DHCP running on the server, with the PDNS of the server and SDNS of ISP DNS server. I have experimented with this for a week now (some clients with static DNS other with DNS provided by DHCP server). All static entries have no errors. All DHCP for client settings, the client will run without errors for a day or two and then they will pop up again.

Thanks...

What is the return value after "Windows cannot determine the user or computer name."?

CoolClark,
The return value is 1722

Sounds like DNS isn't configured properly. Checkout the following link about halfway down the page:

CoolClark,
Thanks for the reply and the article. That is a good site for reference and a good article. I went over that article and the only thing I didn't have was the DNS Suffix, so I entered that and we'll see what happens. But other than that, I have basically everything setup the way the article describes. When clients join domain, they register with DC, I can see host file created and computer while browsing.

Have you came across this before...Once I setup the DC, say the name is The.firstdomain.com, where Firstdomain.com is the registered DNS name. Once client is on network, a private network, they can no longer ping

http://www.firstdomain.com

anymore. I had to create a host file to point to the outside address so they can get there...
I have heard that is normal with private network...have you heard of anything like that??
Thanks

Brilliant link, you answered a question I had for ages... How do you configure DNS correctly?

(sorry if the questions a bit broad... start me off somewhere & I'll get the hang of it)

Cheers

Best practice is to set up your internal network as mydomain.local and your internet domain as mydomain.com so there is no doubt which network your on. That being said a lot of people(including me) have set up their internal the same as their internet domain. What is happening is internally your dns server is authoritative for your domain, so any internal clients look to your dns server for mydomain.com addresses. In order to go out on the internet your dns server has to point to internet sites in the mydomain.com domain which can be entered manually or by syncing with your ISPs dns. Most people don't have more then 3 or 4 external links so doing it manually is probably the best way. Just add the host records for www, mail, ftp, etc.

When I try to add another DC to our domain I get a cannot find forest or domain error

When I run netdiag in the exsisting DC I get a RCODE_SERVER_FAILRE error
No DNS servers have DNS records for the DC

Anyone got any ideas?

It sounds like you are having a DNS failure and that DNS may not be setup properly. Try the link that Coolclark entered above on how to setup DNS, that is pretty good.
Here is another link with lots of error codes:

Thanks for the link
But I still cant get it working

I can ping the domain name and the server
I can even get another server to join the domain but it just wont join AD

it is anything to do with our server having a .co.uk suffix?
