Here's the scenario; You have migrated services provided by one server to a second server. The intention is to get rid of an older server and migrate everything to the newer server. The new server has been given a new name to match current naming conventions. You require that if anyone does a "net view" or a "net use" using the name of the old server, they should be able to see or use all shares on the new server.
You start by creating a a "C" name in DNS that points the host record that belongs to the new server.
From the command line execute a NETBIOS call, such as "net view", against the old server you are greeted with the following message: "You were not connected duplicate name exists on the network"
The problem is that the new server sees that you are attempting to use a "net view" with the wrong NETBIOS name. MS has a hotfix for this but you can resolve this by making the following changes to the registry:
Windows Server 2003
To resolve this problem in Windows Server 2003, follow these steps:
Create the CNAME record for the file server on the appropriate DNS server, if the CNAME record is not already present.
Apply the following registry change to the file server. To do so, follow these steps:
Start Registry Editor (Regedt32.exe).
Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
On the Edit menu, click Add Value, and then add the following registry value:
Value name: DisableStrictNameChecking
Data type: REG_DWORD
Radix: Decimal
Value: 1
Quit Registry Editor.
Restart your computer.
Windows 2000 Server
Create the CNAME record for the file server on the appropriate DNS server, if the CNAME record is not already present.
Apply the hotfix to the computer for which the CNAME record was created, not the DNS server. (Unless the DNS server and file server in question is the same computer, and then all of the changes is applied is to that server.) This hotfix affects the LAN Manager Server Service and does not affect DNS functionality.
Apply the following registry change to the file server to which you installed the hotfix. To do so:
Start Registry Editor (Regedt32.exe).
Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
On the Edit menu, click Add Value, and then add the following registry value:
Value name: DisableStrictNameChecking
Data type: REG_DWORD
Radix: Decimal
Value: 1
Quit Registry Editor.
Restart your computer
