Joining domain

[Kaustubh]

I can't get my windows 7 pc into the domain. please help.

The following error occurs.

An attempt to resolve DNS name of a domain controller in the domain being joind is failed. Please verify this client is configured to reach a DNs server that can resolve DNS name in the target domain.

The domain controller is Win server 2003.
Other Pc having XP get quickly in domain




Please Help

First of all check your DNS Settings: ipconfig /all
Does the DNS Address point to the Server 2003 DC?
Also set your DNS Suffix to your domain name.
Can you ping the domain controller by DNS name?
Can you ping the domain controller by IP?

Hey what version of 7 do you have? Home Premium states it can't join a domain.

Really?

Wow. Didn't know that.

I remember reading rumours of some problems with Vista connecting to a 2003 domain. The solution then was to disable IPv6 and enable WINS in netbios (I know, WINS OMG!).

This worked back then, so you could try it with Win7 and let us know. I'd like to think that Microsoft fixed that little issue though.

Good Luck!

Another approach might be to add the Primary DNS suffix in manually.
Click the MORE button from the 'Computer Name/Domain Changes screen'

Not my favourite choice, but you can always remove it later.

Hi all,

looooong time reader first time poster, so here goes.

i have a sony VAIO that came shipped with Windows 7 Pro. we have jumped through a few hoops to get the laptop on the domain and have lowered the UAC setting so we arent bombarded with login prompts all the time. now we are on the domain it appears we can only ping the laptop against the DC and vice versa randomly. randomly i mean for 30 seconds or more it will return packets. then after that 5 seconds later it will return one packet then drop the rest. after that if you try to ping it again it wont reply at all. this is for both DC and laptop to one and other.

we can ping eveything else even our corporate gateway in another state, but not our local DC.

all the firewalls are dropped but i cant help but think maybe sony have soemthing in their proprietary software which may be causing this to happen. maybe something blocking random ICMP.

another thing that doesnt work is VNC as this works only one way.

if we vnc from the laptop into another pc it works perfectly, however if we vnc to the laptop it will not connect at all. password authentication is turned off on vnc as well.

i am almost bald and started with an 8 inch afro, any help is appreciated.

That's interesting Tom, the only times that I've seen an intermittent droppage on a single domain device is:
- When another device like a printer is sharing an IPadress
- Drivers are bad
- Cabling or NIC is faulty
- It's wireless connection is interrupted

I'm also not sure why you had to lower UAC, I've had no problems on domains with Win7.; but then I don't know your network . Nevertheless, here's a quick brainstorm, including requests for more info so that I can narrow down the troubleshooting with you.

• Is the LAN spanning any subnets?
• What type servers are the DHCP and DC (e.g. Apple, Redhat, WS2003, WS2008?)
• Is the DHCP on the DC?
• Are you using WINS?
• Are you using TCP/IPv4 or v6? If not using IPv6 then disable it, there were some early reports in Vista of this improving connectivity on IPv4 networks (don't ask me how though ).
• Could the issue be a router or a cable?
• What flavour and version of VNC are you using?
• Are we talking about LAN only or is it connected via Wireless too? If so, lets turn off the wireless for testing.
• Are you sure that the IP addy is not shared by another device like a printer. Is it static or DHCP?
• Is there another device on the network with the DC's IP address?
• Is the DC's IPaddress incorrectly mapped in the laptop's host file?
• After packets are dropped and you do an IPCONFIG /ALL is everything showing as it should be?
• When the packets begin dropping, if you ipconfig /flushdns, arp -d, ipconfig /renew can you send recieve packets once more?
• Is DHCP in a server cluster?
• Is there any group policy regarding IP access that may effect you (granted that this is normally On or OFF but worth a check)?
• Are there any services on a delayed start that are kicking in and killing the connection?
• Is the certificate database on the laptop up to date?
• Do you utilise Network Access Protection on your network and is there a NAP server?
• Is an application blocking access to the DC?
• have you updated all drivers from Sony's website not MS update?
• What happens if you add the DC to the laptop's host file?
• Are you using roaming profiles? Or is there another situation where a lot of data is sent during the first few minutes of the connection?
• Sometimes third party software (especially conencted to an SQL server) may deny the connection if it is not configured correctly. Not that I'd be hosting that on my DC, but I want to cover it with you.
• You mentioed that firewalls were down, are you using windows firewall on teh Win 7 laptop? If not did you verify that it was down also?
• If your DC is Non Windows or lower than 2008 you may need to adjust the "Network Security: LAN Manager Authentication Level" in group policy.
• If using an Interface metric on the default gateway is it configured correctly (e.g. 80/20 not 20/80)?
• Perhaps the DHCP is issuing it an IPaddress with a very very short lease
• Is there anything is the event log on either the laptop or the DC?
• Is there anything in the router logs?
