Replication on snapshot

Hi is that possible to configure replication in the following situation.

server A is built by snap of server B. Because i am able to create publisher on server B but i am unable to create same on server A.

could any one explain the situation, why it is happening this way.

any help is appriciated.

if you are curious what kind of error i got.

TITLE: Publisher Properties

An error occurred connecting to Publisher 'SERVER A'.

For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=9.00.1399.06&EvtSrc=Microsoft.SqlServer.Management.UI.PubshrPropertiesErrorSR&EvtID=CantConnectToPublisher&LinkId=20476

ADDITIONAL INFORMATION:

SQL Server replication requires the actual server name to make a connection to the server. Connections through a server alias, IP address, or any other alternate name are not supported. Specify the actual server name, 'SERVER B'. (Replication.Utilities)

BUTTONS:

OK

The @.@.servername is wrong on server A. If you do "SELECT @.@.servername" on Server A, I bet you will see the name of "B". You can do the following to correct it:

exec sp_dropserver 'server B'

exec sp_addserver 'server A', 'local'

Stop and restart the server.

You should be OK now.
