    Question OSX 10.3 & Win 7 question...

    Hello,

    I'm trying to access a mac running OSX 10.3.9 from a Windows 7 Pro with SP1 computer.

    We have 2 mac's on the network both running OSX 10.3.9

    On a Windows XP Pro SP3 computer I can access both mac's with no problems

    However on the Win7 computer I can access one of the mac's fine. But the other mac prompts for a user name and password that I enter and it fails to connect

    Comes back with "logon failure: unknown user name or bad password"

    The same user name and password work fine on the Win XP Pro computer connecting to the same mac.

    Anyone got any ideas why Win 7 is having issues ?

    Thanks Ben

    How are you trying to connect? Via a RDP/remote viewing program or directly?

    Hello,

    Im trying to access the mac via a unc path from the run menu on the win 7 computer.

    The same way works fine under windows xp.

    The mac does have a basic password set, could windows 7 be wanting a more complex password than win xp and thats why it wont let me connect ??
    Thanks Ben

    If anything it would be trying to use SMB2 security to connect and those older versions of Mac OSX were a tad (a lot) rubbish with regard to that. Are the Windows 7 machines domain joined?

    Yes the windows 7 computers are on the domain.

    The 2 macs only 1 is on the domain and listed in Active Directory.

    The mac that is listed in AD i am able to connect to.

    The mac I am struggling to connect to is not on the domain. Put windows xp computers can still connect no problems, its just affecting win 7

    Thanks for the help.

    Yea this sounds like an authentication type issue, are you providing the local computer name as a domain to logon to i.e. computername\username as the domain machines may be trying to pass the domain\username by default for all credentials as opposed to the contextless and thus less secure credentials of XP.

    When the box pops up for user name and password on win7 to access the mac im using the format macipaddress\username - password

    Its not like you say defaulting to the domain\username the windows 7 computer is on.

    It can sometimes send it by default to the host domain despite what it says in the text box, you'd need the macs hostname rather than the ip address though as it won't derefference properly.

    Either in Macintosh HD --> Applications --> System Preferences

    OR

    When on the desktop you can use the Go menu to goto applications --> system preferences

    OR

    Apple icon at top left --> System preferences

    OR

    Hold the Apple ( CMD ) button and press space bar and type 'system' minus the quotes and system preferences should show up as an application which you can click on

    and then the below

    system preferences --> Sharing ( should be a text field which states computer name at the top )

    Thanks that.

    Tried it with hostname\username still no access under windows 7

    Hostname\username under win xp still works fine.

    Must be a setting in win7 somewhere that's getting in the way.

    Thanks ben

    I think this is probably due to the LAN Manager authentication level which defaults to "Send NTLMv2 Response only" in Windows 7. Use the local group policy editor to change it to "Send LM & NTLM -- Use NTLMv2 session security if negotiated". Try changing the setting under Local Policies / Security Options / Network Security: LAN Manager.

    Agreed, you may need to degrade the security on the windows clients to conect, we ditched out old Apples or upgraded the OSs on them as we did not want to drop the security levels on our Windows stuff to do it. We looked for a solution on the mac side but never found it short of the upgrade (in our case it was old unjoined macs connecting to a 2k8 server).

    Your other option would be joining the mac to AD like the other one if it is running the same version and does work.
