Mac: Doesn't play well with others. Doesn't Share. *UPDATED

Vista cannot authenticate when trying to attach to a file share (SMB) on our old 10.2 Mac Xserve. Fixing the problem involves weakening the security of Vista file sharing, but we're all friends here behind the firewall, right?

I stole these instructions from z3r010 on

1. Open the Start Menu.
2. In the white line (Start Search) area, type regedit and press Enter.
3. Click Continue for UAC prompt.
4. In regedit, go to:-HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsa

5. In the right pane, right click LmCompatibilityLevel and click Modify.
NOTE: If it doesn't already exist, create a DWORD value named LmCompatibilityLevel

6. Set the value to 1
7. Reboot

*UPDATE 8-25-2009 – I just had this same problem in Windows 7 and this solution fixed it. -Kris-
