Slow Logins on AD domain

[Necrofuzz]

We have installed a Active Directory using a step by step guide (simple). Configured our DNS and dhcp on the same machine. Added a basic user, after we join the domain with another pc, the login is slow as hell up to 12minutes. I checked the event viewer and we have 2 to 4 userenv errors but have no idea if thats what is causing the slow logins.

Our doman name we decided is simple MCA
we do not connect to the internet. Its an internal network, and we will ad internet availability later.
we used the ip range of 131.107.110.1 - 131.107.110.253

please help if you have any information or have had this problem.

Well 98.9% of the time this is DNS related. I am puzzled why you are using public address space for a private network, you should really use something in the private space. Anyway, does your DC point to itself and only itself for DNS, and not 127.0.0.1 but its internal IP. Is the client pc configured to look at the DC only, for DNS?

Is the DHCP configures to ONLY hand out your DNS server to clients like it should be?

Test your DNS resolution with the program nslookup.exe to see what reply you get. i.e.

Default Server: mydns.mydomain.com
Address: 131.107.110.???
> servername.mydomain.com

Server: mydns.mydomain.com
Address: 131.107.110.???

Name: servername.mydomain.com
Address: 131.107.110.???

enter some more to resolve...
> pc1name.mydomain.com
> pc2name.mydomain.com
> mydomain.com
