Problem installing TCP/IP on NT4.0 Workstation

The workstation is currently running NetBEUI. I have the latest NT service pack installed. I am trying to install TCP/IP on the workstation but keep getting the following error messages during the setup process:
"Registry service subkey already exists"
"Unable to remove Name Space Provider"
I have already removed relevant subkeys from the following registry entries:- HKEY_LOCAL_MACHINE\Software\Microsoft & HKEY_LOCAL_MACHINE\SYSTEM\CSS\Services but no luck yet.

I am using a Dell PC with a 3com Fast Etherlink XL NIC.

Any ideas?

I don't know if you have read KQ Q151237. If yes, don't read the rest and reject the answer.
Maybe you haven't removed all keys:
NOTE: You may or may not have all of the following Registry entries
Depending on your TCP/IP configuration.

NOTE: CCS=CurrentControlSet

HKEY_LOCAL_MACHINE\Software\Microsoft\DhcpMibAgent
HKEY_LOCAL_MACHINE\Software\Microsoft\DhcpServer
HKEY_LOCAL_MACHINE\Software\Microsoft\FTPSVC
HKEY_LOCAL_MACHINE\Software\Microsoft\LPDSVC
HKEY_LOCAL_MACHINE\Software\Microsoft\NetBT
HKEY_LOCAL_MACHINE\Software\Microsoft\RFC1156Agent
HKEY_LOCAL_MACHINE\Software\Microsoft\SNMP
HKEY_LOCAL_MACHINE\Software\Microsoft\SimpTcp
HKEY_LOCAL_MACHINE\Software\Microsoft\Tcpip
HKEY_LOCAL_MACHINE\Software\Microsoft\TcpipCU
HKEY_LOCAL_MACHINE\Software\Microsoft\TcpPrint
HKEY_LOCAL_MACHINE\Software\Microsoft\Wins
HKEY_LOCAL_MACHINE\Software\Microsoft\WinsMibAgent

HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\DHCP
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\DhcpServer
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\FTPSVC
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\Lmhosts
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\LPDSVC
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\NetBT
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\SimpTcp
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\SNMP
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\Tcpip
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\Wins
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\WinSock
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\WinSock2
HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\'NetDriver'x\Parameters\Tcpip
where NetDriver is the name of network card installed on system and
where x is the number of the network adapter.

It may also be necessary to remove the following keys:

HKEY_LOCAL_MACHINE\System\CCS\Enum\Root\Legacy_DHCP
HKEY_LOCAL_MACHINE\System\CCS\Enum\Root\Legacy_Lmhosts
HKEY_LOCAL_MACHINE\System\CCS\Enum\Root\Legacy_LPDSVC
HKEY_LOCAL_MACHINE\System\CCS\Enum\Root\Legacy_NetBT
HKEY_LOCAL_MACHINE\System\CCS\Enum\Root\Legacy_TCPIP
HKEY_LOCAL_MACHINE\System\CCS\Services\LanManServer\Linkage\Bind
HKEY_LOCAL_MACHINE\System\CCS\Services\LanManWorkstation\Linkage\Bind

NOTE: Removing these additional keys requires manipulation of the rights on
those keys. The default rights for Everyone is READ. This needs to be done
for each key you wish to remove. To change the rights, log on as
Administrator, run Regedt32.exe, and select the key you want to delete.
From the menu, select Security, Owner, Take ownership. Then, Select
Security, Permissions, and give full control to Everyone, selecting
"Replace permission on existing subkeys."

Reboot the computer so that Registry changes are recognized by Windows NT.

Thanks for your quick reply schmiegu - but I have read the article and done what it asked, and still no luck.

Any other ideas?

Remove all Networking components. Reboot and re-install them. I had the same problem and this is how it got solved.

Sorry MFK, I've already tried that too! I removed all network adapters, protocols & services - rebooted the PC and then resetup networking selecting both NetBEUI & TCP/IP - still the same problem when TCP/IP was being setup. Only startup, NetBEUI is fine but no TCP/IP.

Any other ideas?

Which network card do you use? Maybe, there's a problem with the .inf
If selecting another adapter doesn't solve the problem, try regclean.exe - sometimes it helps, else: reinstall NT (maybe upgrade could be enough, but I don't believe it)

Thanks for your help gasim. The bit that really helped me what how you expanded which key I had to edit - I did not realise when I first edited the registry that "CCS" was short for "CurrentControlSet" and of course did not delete any of the keys under this.

All up and running now - thanks

You are wellcome
