spoofing server name for file sharing

I have users using Solidworks that connect to a specific UNC path for their library of parts (it is simple file share).

\\oldserver\solidlibrary\

I have to retire the server and want to move the file share to new server

\\newserver\solidlibrary\

This as it turns out will create a need for the users to modify refrences in their "assemblies" (projects) and will be quite time consuming as they would have to do it to each project.

Is there a way to "spoof" oldserver's name in DNS so that they would connect to the new file share using old UNC path?

Once you copy the data over to the new server and shut down the old one you can simply make a DNS entry that maps the old server name to the new servers IP address.

This can be done by making a new A record or Cname with the old server name.

I think I have tried this in the past and there were some authentication issues with this.
I will give it a try tonight.

I tried it - I copied the data to new server, created share, created DNS record in DNS to spoof the name and I get folowing error:


\\oldserver is not accessible. You might not have permission to use this network resource. Contact the administrator to find out if you have access permissions.
Login Failure: The target account name is incorrect.

I can ping the "oldserver" name and it resolves to the "newserver" IP
, and I have no issue to access the share by \\IP_ADDRES\SOLIDLIBRARY

but can not access by \\oldserver\solidlibrary

If the old computer account is still in active directory you will get these issues the old computer account must be removed before name resolution will work correctly

I have tried CNAME instead of A record and it started to work.
Did not have to remove old server from AC.

Thank you xxdcmast

Glad to hear. I believe a record would have also worked if the computer Account was deleted from ad but the finance sefinitely is safer.
