"The network folder specified is currently mapped using a different user name and password"

or

"Multiple connections to a server or shared resource are not allowed.
Disconnect all previous connections to the server or shared resource and try again."

Seen under the following scenario:

• This has been seen on Windows-based computer that is running Microsoft Windows Server 2008, 2012 R2 and Windows 7 SP 1.
• There are two network shares on a remote server.
• You use user credentials to connect to one of the network shares.

To work around this issue, use one of the following methods.

Method 1:
Use the IP address of the remote server when you try to connect to the network share.

Method 2:
Create a different Domain Name System (DNS) alias for the remote server, and then use this alias to connect to the network share.

After you use one of these methods, you can use different user credentials to connect to the network share. In this situation, the computer behaves as if it is connecting to a different server.
