Solved: “The username you entered could not be found” when connecting to network share on windows O.S.

If you try to connect to a network share you may receive the error:

“\\name of computer is not accessible. You might not have permission
to use the network resource. Contact the administrator of the server
to find out if you have access permissions”

And the message: “The username you entered could not be found.”

You also have the rights to access the share, no firewall problems, and your user is not locked out or expired.

The solution is to open the command prompt and type:

Control keymgr.dll  

windows vista:
image

windows 7:
image

Find the address of the server and delete it from the cached credentials, try to reconnect and .. it should works.

dnslookup VS ping : 1-0

Problema: il ping non sembra risolvere correttamente un indirizzo mentre nslookup è ok.

OPERAZIONI:

Ping miosito.miodominio.it : BAD ADDRESS >> (deve essere un 192.168.1.10)

Nslookup miosito.miodominio.it : OK >> è 192.168.1.10

ipconfig /displaydns: mostra che la cache DNS contiene l’indirizzo sbagliato

ipconfig /flushdns: pulisce la cache dns ma il ping COMUNQUE risponde con l’indirizzo sbagliato

SOLUZIONE:

net stop Dnscache

net start Dnscache

E l’indirizzo viene risolto correttamente!

Nslookup interroga direttamente il server DNS.

Il ping utilizza invece la cache DNs fornita dal servizio Dnscache.

Se il Dnscache si incricca… riavviarlo risolve il problema

La domanda successiva (senza risposta) è:

Perché il servizio DNSCache risolve l’indirizzo utilizzando il DNS secondario (internet) e non quello primario (intranet) ?
