How do I purge or empty Windows Explorer's network username and sharename cache?

While troubleshooting a Samba vs Windows Network issue, I noticed that Windows' Explorer remembers login credentials of remote shares, even if you ask it not to. For instance, after accessing a share using \\servername\sharename plus entering username/password and then closing Windows Explorer, adding the same share as a network drive gives the following message, regardless whether the username is the same or not:

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

To connect using a different user name and password, first disconnect any existing mappings to this network share.

Using NET USE does not show the share. After restarting the computer, I have no problems accessing the share using different credentials. But restarting just for testing other credentials is annoying, esp. while troubleshooting. How can I purge this cache, using Windows Vista?

^{Note: using nbtstat -R[R], ipconfig /renew, killing explorer.exe or disabling / re-enabling the network card didn't help.}

Solution 1:

The following advice does not help you to 'purge or empty Windows Explorer’s network username and sharename cache' (as you asked). But it will allow you to connect to (essentially) the same share or the same server using a different username.

The trick is to use the IP address of the remote server.

(Also,

if it's Samba on the remote side,

• you could setup smb.conf to contain netbios aliases = firstname, secondname, thirdname and you'll have even more options

if it's a Windows AD member server on the remote side,

• you could create a different 'Domain Name Alias' for your server,

and you'll have even more options. In all these situations, the connecting client will behave as if it connected to a different server.)

Solution 2:

Logging out and logging back in will clear the credentials.

You can also try restarting the "Computer Browser" service. That seems to force some type of refresh (although it may take a few seconds to take effect).
