DNS Name Issue

Hey everyone,

 I have a slight problem on my Active Directory DNS Server. For some reason if the name of a computer is SCSjgyl1rr-D  it gives me an error message on joining the domain however, if my computer name is something like IS00. It can join fine. It seems the length of the computer name for DNS is to long. How do i fix this ?

ehhh .... shorten it ? Or is it a problem ?
And leave the " - " out .It's probably causing the error ...

dashes are fine.

search AD to see if that PC account already exists

can you look in the event log on the PC and server to see if there's any indication what the error is.

Posting the actual error message you're getting would also be good. That name doesn't look too long, here's a page with info on limitations:

Unless your domain naem is increadibly long like..... thisisthenameofmydomainandnotyours.local then that name shold not be too long. As already said, dashes are fine, ignore anyone who tells you that they will cause an error. I have lots of PC's and servers with dashes in there names.

What is the exact error you get.

The error states it cant get a response back from the DNS server. However, i took the -d out of the name and it connects fine to the domain.

Post an ipconfig /all


Make sure the client is only pointing to Domain Controllers for DNS

The error points to you not pointing to internal DNS servers like your Domain Controllers in your TCP\IP properties. Please post the ipconfig /all

I avoid using dashes but I guess that's a personal choice.
I tend to avoid them as I run into some problems running MS Access.
So I begun using " _ " instead. I know dashes work in most cases (and they should),
but it's me who's distrustful.  Some routers also tend to have problems with dashes...
Your call ...

like posted before, check the network settings and post the ipconfig /all from both the client and server

The DNS on my IP Config all is pointed to the DNS server. If that was the problem it wouldnt connect without the -d. Thats not the problem. Its the "-d " . However i dont understand why the "-" is an issue.

have you ever used that name in your active directory before and removed it?  if so there may be remnants that could be removed using ADSI edit.

You didnt do something daft by accident and use a space befroe the dash? I know iv'e done such things in the past

So you change the PC Name to SCSjgyl1rr-D and Reboot.
Try joining the domain and it fails?

Change name to IS00, reboot
Try joining SAME domain and it works?

SirusComputersAuthor Commented:
Neilsr yes. the -d is what throws it.

JammyPakCommented:
when you join the domain are you using the NetBIOS name or DNS name? try using dns name.

desailleCommented:
yeah, when joining make sure you are using domain.local

Wierd things throw it off.  I use dashes in all my PC and server names.

SandeshdubeyCommented:
You need to disjoint the PC from domain.Login to DC delete the computer object from AD also delete the old name assigned to PC.

Similary in DNS you need to delete the host recoed of the client here also you need to delete the all record of PC.As you have mentioned that you have tried adding the PC with different name so there will be the recoeds created in DNS as well as in AD.

After deletion wait for the replication to take place between the DC if multiple dc are in the environment.Once the replication is complete try to add the PC to domain with  SCSjgyl1rr-D name.

Hope this helps...
