Yeah, I suppose Ruud didn't feel that it required explanation as it sort of mimicks the NET USE which does have the switch as well.

For further information please take a look here.

Microsoft NET USE in XP
 

Quote:

/persistent:{yes | no} : Controls the use of persistent network connections. The default is the setting used last. Deviceless connections are not persistent. Yes saves all connections as they are made, and restores them at next logon. No does not save the connection being made or subsequent connections. Existing connections are restored at the next logon. Use /delete to remove persistent connections.
