cpqt asks:
Trying to access Mac server using Windows Vista. I know that the server admin is setup correctly. I have no trouble accessing with Windows XP, but none of my Vista machines will work. I continually get invalid user or password. And I’d like to know why when I type in the user name it shows the name of the computer name/user name, i.e. COMPUTER/username. Does that have a bearing on the invalid user name? Can it be a NTLMv2 issue?

To give credit, this was posted on the vistax64 forums by the user Jimmy Brush.
However, this isn’t available in Home Premium. So a registry edit is needed. User Malke on the same forum posted this in a different thread:

1. Run the registry editor and open this key:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsa
1. If it doesn’t already exist, create a DWORD value named
LmCompatibilityLevel
3. Set the value to 1
4. Reboot

Both seemed to have positive results.
