Hi All,

I'm having problem in accessing a shared folder using DNS alias name (CNAME) the setup is like the following:

I've assigned several IP address into a single NIC on my Windows Server 2003 x86 Std.

Server1 - real IP address: 192.168.1.5
Additional IP assigned to the same NIC on Server1:
192.168.1.10,
192.168.1.11,
192.168.1.12,
192.168.1.13

then i created A record in my DNS server:
192.168.1.10 - Alias1
192.168.1.11 - Alias2
192.168.1.12 - Alias3
192.168.1.13 - Alias4

when i go to run and type the following test:
"\\Server1\SharedFolderName" it went fine
"\\*Real and Alias IP Address*\SharedFolderName" it went fine
"\\*DNS Alias Name*\SharedFolderName" it error ?

is there anything that i can do to access it using a DNS alias name ?

thanks.
Error message:
 
\\alias2
You were not connected because a duplicate name exists on the network. Go to System in Control Panel to change the computer name and try again.

I'm talking about one NIC, two IPs (multihome, same IP subnet)

the purpose is to test my custom application using four different FTP sites which serves a file from different directory on one single Windows Server 2003.

"then i created A record in my DNS server:"

So did you create an A record or CNAME?   Did the server have its name registered automatically and then you created another A record for it?  If so, remove the newly created A record and create a new CNAME (Alias2).

oops actually it's A record not a CNAME (pardon me).

This is a known problem in Windows 2003 that requires a registry tweak in order to work.  Do this: Start Registry Editor (Regedt32.exe).
  1. Locate and click the following key in the registry:     HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters    
  2. 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

Way too late since you already found it :)

But for completion it is discussed in this KB article a security feature rather than a problem as such:

This one might also be of interest, the loopback check can prevent to accessing via the alias name locally (should that be necessary):
