Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

We are in process of setting up disaster recovery site, have a bit of problem.

Right now we are replicating AD server to our DR site and rest of everything is duplicate setup.

Issue that i am facing is, we have file share named //FileShare01/Folder1. We are using this fileshare to save roaming profiles. So from DR site as well it need to find this file share. So i tried putting in host file entry for 'FileShare01' to another server.

But i am getting 'login failed: target account name is invalid' with above setup when try to access that fileshare.

Ping resolves the correct ip from host file entry. I am logged in as user which has rights to access folder. I can access folder using ip or servername. But not using host file entry.

What is wrong here?

So you're saying that you have another server (FileShare0x) and you're trying to make it answer as if it was FileShare01? If so, then you'll need to make a change to FileShare0x to make it listen on the alias FileShare01. The following is an excerpt from the MS KB article that explains the steps:

To resolve this problem in Windows Server 2003, follow these steps:

A. Start Registry Editor (Regedt32.exe)

B. Locate and click the following key in the registry:

C. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

D. 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

E. Quit Registry Editor

F. Restart your computer

You may also have to set the SPN (Service Principal Name) for the Alias Name.

For example, you may have to enter a command that resembles the following commands:

setspn -a host/aliasname targetserver
