In a WAN environment with high network latency, you can enhance transfer performance by increasing the sizes of TCP send and receive windows.

When View Transfer Server is installed on Windows Server 2008, the TCP send and receive windows are increased to 640KB by default. You do not have to reconfigure these values.

When View Transfer Server is installed on Windows Server 2003, you must manually set registry keys to increase the TCP send and receive windows to 640KB.

Verify that View Transfer Server is installed on a Windows Server 2003 operating system.

1

Start the Windows Registry Editor on the Windows Server 2003 computer on which View Transfer Server is installed.

2

Add two new registry keys called DefaultSendWindow and DefaultReceiveWindow to HKEY_LOCAL_MACHINE, System, CurrentControlSet, Services, AFD, Parameters.

3

Set the DefaultSendWindow and DefaultReceiveWindow key values to 655360.

You must type a positive integer. The values are configured in bytes. The key types are REG_DWORD.

4

Restart View Transfer Server.
