New PC can't be named same as old?

Greetings,

My boss just got a new PC running Windows 7. We are on a SBS2003 network and he has several remote PCs configured to dial in remotely via VPN. The PCs are configured with all the settings saved so he can just click, connect and go. Rather than cjange all the configurations on the remote PCs, it seems easier to just name his PC the same name as the old one. However, when I try to name it, I get an error message stating that the name is taken even though the old PC is disconnected, powered off and sitting on a shelf in my office. Any ideas on why or how I can change the new PC name to the same as the old one? Thank you.

Open Active Directory Users & Computers, under My Business > SBSComputers you should find the computer name.  Just delete this object then you will be able to use the http://connectcomputer wizard on the new computer.

Glen KnightCommented:
Sorry, that should have been http://servername/connectcomputer/ where servername is the name of the SBS server.

OK when I choose delete, there is a box that says "Mark each selected Exchange mailbox for deletion" and it is checked, and I cannot uncheck it. I don't under any circumstance want to delete his mailbox. What is this box telling/asking me?

What are the hacks that forever changed the security industry? To answer that question, we created an exciting new eBook that takes you on a trip through hacking history. It explores the top hacks from the 80s to 2010s, why they mattered, and how the security industry responded.

 
Glen KnightCommented:
And you are deleting the computer account (it has a computer icon) and not the user account?
0
 
bbiitAuthor Commented:
Yes, it has a computer icon, and it is warning me that there are other objects associated with it and asking me to select those associated objects that you also want to delete. Then there is only one option in the box (as noted above) and I can't uncheck it.
0
 
Glen KnightCommented:
You can ignore that warning as computer accounts don't have mailboxes.

OK. The PC is renamed. One weird side effect, though. I cannot ping it from my PC and therefore cannot connect via remote desktop. Any ideas?
0
 
Glen KnightCommented:
that is most likely down to the windows firewall.  Disable it and see if that helps.

His PC Firewall and mine are the same, he can ping me, I cannot ping him. His PC can remote into mine, I cannot remote into his. Please let me know if you have any other thoughts.

Glen KnightCommented:
have you enabled remote desktop on the computer?

bbiitAuthor Commented:
yes

bbiitAuthor Commented:
Strange. I have three other Windows 7 PCs on my network and we all have the same Remote Desktop / Firewall settings and his is the only one that will not allow connections.

Glen KnightCommented:
is it a Windows 7 Professional/Enterprise?

bbiitAuthor Commented:
Professional.

Glen KnightCommented:
what other security software do you have on it?

If you do an IPCONFIG /ALL is the subnet, gateway and DNS server the same as the others?

bbiitAuthor Commented:
Yes.

bbiitAuthor Commented:
So strange.

Glen KnightCommented:
can you disable remote desktop and then apply, then re-enable it.

Can you telnet to the new computer on port 3389?
0
 
bbiitAuthor Commented:
I'll try the disable/enable.

Sorry, but I'm not sure how to telnet. If you can tell me how, I'd love to try.

bbiitAuthor Commented:
disable/enable didn't do it. Thanks for sticking with me.

bbiitAuthor Commented:
OK. I can ping him by IP address, but not by name. Does that help any?

Glen KnightCommented:
on the new computer from a command prompt run IPCONFIG /REGISTERDNS

On another client run IPCONFIG /FLUSHDNS and then try pinging by name again

"on the new computer from a command prompt run IPCONFIG /REGISTERDNS"

"the requested operation requires elevation"

not sure what that means.

Jerry MillsCommented:
You need to run command prompt as administrator.  Right click on cmd icon and select administrator.

bbiitAuthor Commented:
OK. Got it, but it still cannot find host.

Jerry MillsCommented:
Did you join the new computer to the domain?  That will register it.
0
 
bbiitAuthor Commented:
Yes. It is on the domain.

ReneGeCommented:
The easyst, is to delete the PC name in your Active Directory, then join the new PC to the domain.

Glen KnightCommented:
ReneGe, please read all posts before commenting.  Had you have done you will see that has already been done!

Jerry MillsCommented:
You say you can ping the IP address but not the host name.  Go to the command prompt and perform a 'nslookup  bosscomputer.domain.name'  - It will resolve through the DNS server you are using and will tell you if it cannot resolve.  You may be pointing to the wrong DNS server.

should look like:
Z:\>nslookup jerrypc2.ics.local
Server:  idealdc.ics.local
Address:  192.168.1.10

Name:    jerrypc2.ics.local
Address:  192.168.1.23

Glen KnightCommented:
When you do an IPCONFIG /ALL is the DNS server listed on both machines the IP address of the SBS server?
0
 
ReneGeCommented:
@demazter

Sorry for that ;-(

My comment was following "bbiit"'s statment: Yes. It is on the domain.

Looked like an easy one.

My apologies

I'll let it go. If I see my help is needed, I'll then contribute.

Cheers

Also, just out of curiosity, I joined to a workgroup, logged off, then back on, and rejoined the domain. Still no luck. This is nuts.

Computer is registered but you can not ping the computer name.

you can ping the IP
Are you sure the IP is on that computer (and only that computer-- might be an IP address conflict)?
Ping the IP from a second computer (disconnect the cable can you still ping it )

If it is dynamic try
     ipconfig /release
     ipconfig /renew
If you get the same IP address try to assign a empty ip address as static IP to the new computer for testing.
can you ping the IP
can you
       ping -a 10.10.32.32  to see what computer dns thinks it is
[next time rename and disconnect the old computer first before you remove it from the network]

Everybody is on the same path here.  It may be time to get out Wireshark.  Besides duplicate IP address which daniel mentioned - you may be experiencing MAC address blocking, filtering or duplication.  So question is:  Is the computer your pinging from and the bosses computer on the same collision domain (lan address).  

Wireshark will very quickly reveal what is going on.

I would also suggest you find a host (node) on the same wire (switch) and make sure you can ping it from your test station.  If you can - switches can block MAC addresses - try cycling the power on it.

Otherwise try wireshark - download it on to the bosses computer.  Start a continuous ping from your test computer to the bosses computer.  Then start wireshark and capture packets in the promiscous mode.  If you can't see ping request you got network problems.

When all this is over, I owe you some points for solving my original problem. It has kind of morphed into another issue.....

Jerry MillsCommented:
Wireshark is a Free packet sniffing utility.  As ReneGe said:  www.wireshark.org.  A very powerful tool that can monitor tcp streams (conversations between computers) etc.  Allows you to see what is really going on.  I have frequently found inexpensive routers that pass packets for one address but block another - yet their are no ACL's (access controls / rules) set to block it.  Power cycling often fixes problem as the routers little brain is scrambled.  Switches too can block mac addresses - really weird stuff.

With a packet sniffer the network has to yield the truth.  You should try it and keep a small hub 10/100 or small switch that span's ports(mirroring) so you can monitor any point in your network.

Hey BBIIT, check the, #1. HOSTs file and see if anything is jacked up in there.

Also, #2. I have had similar situations where I needed to blow away the TCP/IP stack/WinSock repair, reboot and Windows will auto-load it back.

Here is a link to look at. Some of the things you have already tried. It is just a thought and will certainly not hurt to look into.

Sorry, if you do not know where the HOSTs file is located then let us know.

The above link I posted is for Winows 7. (You can also do this WinSock fix in XP/2003 as well.)

Sorry, my PC BSOD'd right after I posted yesterday and then the hard drive started making loud noises. I had to rebuild.

Yea, go to C:\Windows\System32\drivers\etc  and open it with notepad

It should look something like this:

Guys,

OK. We finally gave up and just gave the PC a brand new name on the domain. All is well as far as connectivity, VPN, remote desktop, etc. However, demazter helped me with my original question, which kind of morphed into a connectivity issue, so I feel like I owe him some points. Can I give some points to him without "accepting" the solution? Thanks guys!

With Demazter as an assist, I believe:

This was correct, but the issue morphed into a new problem, which I later resolved myself. Thanks, demazter!
