Sync Center error - not enough quota

When synchronizing files from my Windows Server 2003 R2 file share to my
Windows Vista Beta 2 Business Edition computer where I am logged on with
admin privileges, I receive the error "not enough quota is available to
process this command" after Sync Center synchronizes some of my files. I do
*not* have quotas enabled on the server or the client.

Why do I get this message and how do I get the rest of my files to
synchronize successfully?

In Windows Vista where the “Enable Quota Management” is not checked, I even
added a quota entry for my user account and configured it to no limit (even
though the quota entry displays 0 bytes in the Amount Used column.

Thanks in advance for your help!
