We changed the computer name on a Windows 7 Professional client and now it cannot access a shared folder on a Windows 2008 server in a Windows SBS2003 domain environment. The SBS2003 is the domain controller and the 2008 server is an application server. The client can access shared folders on the SBS2003 server but not on the 2008 server. The error message received is;
\\SHAREDFOLDERNAME is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
Logon Failure: The target account name is incorrect.
I have already tried removing the client from the domain and adding it back and that did not resolve the problem. Also, when viewing the network from the client, the 2008 server is visible but not accessible. Likewise, when viewing the network from the 2008 server, the client is visible but not accessible.
Tech support for the application said the 2008 server is remembering the host name associated with the original MAC and we need to find a way to reset the hostname/MAC on the 2008 server but I don't know how to do that.
