Are all workstations (or at least 2 or 3) showing that behaviour?

If antivirus on the server is scanning uploaded files, that will slow uploads. Try turning off real-time scanning, or exclude a folder where you can upload some test files.

If it's actually SBS 2003 R2, in a lot of small networks the disk subsystem in the server is overloaded. Run PerfMon on the server and look at the Average Disk Queue Length counter (Google it for interpretation).

Beyond that you'll have quite a bit of work looking at running processes on the server, and network configuration (P2P vs domain, DNS, router/gateway etc. etc.)
