So following my purchase of a nice and heavy Proliant Dl380 G3 server, i'd thought i'd try setting it up on my home network. Installed W2K3 R2 (not enough umph for W2K and selected options for email, file, dhcp, dns and DC. Havent a clue if i need anything else but lets start somewhere. So after setting the server up as a DC and my domain name as twizzle.home i try connecting a Win7 pc to it. But the Win7 fails to find teh Domain. I get An Active Directory Domain Controller (AD DC) for teh domain "twizzl.home" could not be contacted. Ensure that the domain name is typed correctly. If teh name is correct, click details for troubleshooting information. Clicking trouble shooting gives me:- Note: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt. The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "twizzle.home": The error was: "DNS name does not exist." (error code 0x0000232B RCODE_NAME_ERROR) The query was for the SRV record for _ldap._tcp.dc._msdcs.twizzle.home Common causes of this error include the following: - The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses: 192.168.1.1 - One or more of the following zones do not include delegation to its child zone: twizzle.home home . (the root zone) Now i have tried ping from server to PC and back and thats fine. does the error message mean i have to wait a day for teh DNS on my ISP to get updated with my internal domain name? if so why? Shouldnt i be able to conenct to my domain straight away as its only and internal one not used on teh web? Or am i barking up teh wrong tree? I have no clue when it comes to servers and found teh MS press book 290 to be confusing too.
