We have a server running SBS 2003. We have 3 Macs in the office. Two of them do just fine, but the newest and best one has a very slow connection to shared folder areas and only has read privileges when it does connect. It's a MacBook Pro running OS 10.6.4. It's on a wired connection to the network. It connects to the server using the smb:// protocol.
The user is already a member of the Administrators group, so he should have complete access. On top of that, I have gone into the specific shared folder he's trying to access and added his username for complete access.
I don't know where else to go from here.
