Navigating through public folders is extremely slow after upgrading users to Windows 7 Professional X64 edition. Before when our users were on XP this wasn't an issue.
Steps we've taken:
1. Uninstalling and reinstalling Office
2. Deleting the user's mail profile and recreating it
3. Checking the duplex speed of both the NIC and the port on the switch one of the problem PCs is plugged into.
The OS is: Windows 7 X64 Professional
The server these public folders are stored on is: Windows Server 2003 R2
The only slowness these PC's are experiencing is with the public folders.
