SymptomsWhen I run the P2V migration tool, I get the following error message:
VZAgent Error 425. Distribute agent to 10.4.4.1 failed : connection :  Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.
CauseThis error occurs when one or more SMB connections for the P2V migration related to the same user already exists. Microsoft prevents you from making more than one SMB connection to a single shared resource using the same credentials.
ResolutionFrom a DOS prompt, run the following command to check all opened SMB connections:
If there are any connections to the source server, close them prior to the migration (as illustrated below):
net use \\<source server name from the list> /d
Rerun the net use command to verify that no SMB connections are remaining and then run the P2V migration again.
