OK so I kept having this issue with a clients Windows 7 Ultimate PC, every time I would try to map a network drive it would ask me for 2 pairs of credentials. The Regular credentials and then the dreaded “enter network password” credential. Keep in mind that this is a business network so no clients have home groups setup.
Troubleshooting Steps: – Went to Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings and made sure “Password Protected Sharing” was OFF.
– Still didn’t work. – This time I had to check our credentials manager and remove all old credentials it may have stored ( Control Panel\All Control Panel Items\Credential Manager )
– Still Didn’t work WTF! right? At this point I was kinda annoyed and I decided to check the Network Policies on the local computer, TADAAAAAAAA :P
Start Menu Type run or cmd in search box
Go to Local Policies | Security Options and choose the “Network Security: LAN Manager Authentican Level” item Set it to “Send LM & NTLM use NTLMv2 session security if negotiated”
Reboot, Remap and everything should be good, enjoy :)
