Vista & Network Shares

NickM · 16 Mar 2007 at 16:30

Got my new vista PC today, it connected to my network fine via DCHP. I can access the net, access protected shares on one computer and unprotected shares on my XP comp but when I try and access protected shares on my NAS it says "logon unsucessful, windows was unable to log you on. be sure you user/pass are correct". I am sure that they credentials are fine and its not an issue with the NAS because my 2 other computers (XP) can access it.
Any ideas?

edit: when I use the guest account (no password) it lets me see the list of shares but then when I try to access a protected share it says "\\nas\shareP is not accessable. you might not have permission to access this rescource..."

I think it's the default security level for logins -

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\LMCompatibilityLevel

controls the security level mandated or allowed for logins. In Vista it defaults to 0x3, which means "NTLMv2 only". This is not supported by Samba (Mac OS X, Debian Sarge, or Buffalo TeraStation). This is despite the fact that the Samba documentation implies that it should work.

The fix is to change it to 0x1, which means "use NTLMv2 if available, or older versions if not." Reboot.

Odd, I can connect fine to Samba on a machine running Debian Sarge - but Vista doesn't remember the username/password.

Excellent! It (terrastation) works perfectly now! Thanks for the very quick reply

Yeah i have that problem too with my WD Netcentre and a password protected share. in xp it used to remember the username but in vista it doesnt, its most annoying having to type that in everytime.!!
