Greetings - I could use an expert on this. We have a Win2003 network/WAN using a 256k VPN tunnel. The performance when trying to copy files and add/print is very poor.
We had the WAN line tested, and had Microsoft look at the server.
Our throughput seems fine using HTTP or FTP transfers. Using SMB (file copy, printing) is very poor or timing out. I'm getting RPC timeouts too. Is there anything in the WAN that can cause this? Wish I had more details - not a network engineer.
