Networking with iMac

Has anyone heard of problems trying to connect to an iMac for file sharing,
from a PC running Vista?

When running Vista, I can connect to all devices on my network except the
iMac, which is running OSX. I can connect to all devices, including the
iMac, from another PC that is running Windows XP. I can also connect to the
iMac from the Vista machine using PuTTy with SASH.

When I try to file share with the iMac using the Vista networking features,
I get a login prompt, but when I enter my username and password, I get a
"login unsuccessful" message. I've tried every combination of domain and
username I can think of. Windows help screens won't even recognize the term
"iMac," so I can't find any help there.

You need to do a little extra work to network Vista with *nix systems,
including OS X. I'm assuming that you've 1) got your Windows sharing set
up correctly on your Mac; and 2) you've created identical user
accounts/passwords on all machines.

To enable Windows Vista to connect to Mac OS X with Windows File Sharing
enabled, you will need to change the following policy in Windows Vista:

Start>Run>secpol.msc [enter]

Click on "Local Policies" --> "Security Options"

Navigate to the policy "Network Security: LAN Manager authentication
level" and double-click it to get its Properties. By default Windows
Vista sets the policy to "NTVLM2 responses only". Use the drop-down
arrow to change this to "LM and NTLM – use NTLMV2 session security if
negotiated".

In Vista Home Premium, you won't have this tool so per MVP Steve
Winograd, do:

1. Run the registry editor and open this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa

1. If it doesn't already exist, create a DWORD value named
LmCompatibilityLevel

3. Set the value to 1

4. Reboot

The change to the registry fixed the problem. I would have never figured
that one out.
Thanks,
