Connecting a MAC to a Longhorn Server
Andy Malone writes:Basically MACs run V1 and Windows Server 2003, Longhorn & Vista run V2. To fix this small issue follow the following steps:Upon teaching a recent Longhorn Server MasterClass, one of my delegates asked if it was possible to connect a MAC to a Widows Longhorn Server / Vista based network. Initially it appeared that the MAC would not connect, even though it had a unique IP address etc. After much soul searching we discovered that in order for the MAC to participate we would have to downgrade to a lower level of NTLM authentication.
1. Either in Group Policy Management Console / Local Security Policy
2. Navigate to Security options – Network Security – LAN Manager Authentication
3. Double click – You will notice that V2 is the standard. To enable MAC connectivity either enable a dual V1 & V2 option or downgrade to V1
4. That’s it!
