how to disconnect a windows share dir by known IP?

windows only record 1 user/pwd to a remote share dir,

and my program need to connect a dir,

but the user may login first, let my program failed to connect,

is there a method to disconnect it? i only know the IP.

I use wnetcancelconnection2(remotedir) first, but still cannot work,

and return 1219 error(credentials supplied conflict with an existing set of credentials)

From stackoverflow

• net use \\10.0.0.1\sharename /user:domain\user

  to disconnect

  net use \\10.0.0.1\sharename /delete

  linjunhalida : not the command-line way, but the programming way.

• To disconnect one single computer/ip from a share. Use net session \IPADDRESS OR NAME /Delete or Net Session /delete to disconnect all client connections. You must run this command from the server which holds the share that is being connected to.

  Of course im not quite sure i read your question correctly.

• See source code for "net use"

  Anonymous : Is it open-source?

  Isaac : @limace - No it's not!

• Have you tried the NetUseDel function?

  NetUseDel Function

• sipwiz is right :

  net use \10.0.0.1\sharename /user:domain\user

  to disconnect

  net use \10.0.0.1\sharename /delete

  (sorry sipwiz, can't vote for your answer yet ...)
