Certain "tools" will hold the connection open even if you "net use * /del"

For example, DumpACL (dumpsec) will hold the connection open and cause a
credential conflict. So close this kind of stuff first. Then "net use *
/del" then try to connect with new credentials.

<QUOTE>
A set of credentials consists of a user name and a password. Both File
Manager and NET USE allow you to specify a parameter that designates
which user account you want to use when you connect to a server. If you
make a connection to a server using one account, then make another
connection to the same server using a different account (with the first
connection still intact), you receive the above error message. To make
the connection with the other account, disconnect the previous
connection(s) to the server.

Hi,

Upon hitting the following command :
" Net use z: \\otherhostname\resourcename$ * /user:otherusername " I
only get: " System error 1219 has occured. The credentials supplied
conflict with an existing set of credentials. " My whole net exists of
NT4.0 . I try to login as one user and assign myself another user's
resource, using the right password. any suggestion ?

thx
centipede
