Improve Transfer Performance Over a WAN on Windows Server 2003
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.
Prerequisites
Verify that View Transfer Server is installed on a Windows Server 2003 operating system.
Procedure
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.
View Transfer Server Status
View Transfer Server can be in various states of operation and availability. In View Administrator, you can
track the status of View Transfer Server in the Transfer Servers pane on the View Configuration > Servers
page.
Table 13-1. View Transfer Server States During Normal Operations
Status Description
Ready View Transfer Server and the Transfer Server repository are configured and operating
properly.
Pending View Transfer Server is being added to View Manager or is exiting Maintenance mode.
View Connection Server is actively establishing a connection with View Transfer Server.
When the connection is made, View Transfer Server will be moved to an operational
state such as Ready.
Maintenance mode pending View Transfer Server is entering Maintenance mode while waiting for active transfers
and package publish operations to be completed.
Maintenance mode Active data transfers are suspended. Users cannot initiate new transfers. Scheduled,
pending transfers cannot take place. View Transfer Server cannot publish packages to
the Transfer Server repository.
Initializing Transfer Server
repository
View Transfer Server is initializing the Transfer Server repository.
If View Transfer Server has trouble initializing the Transfer Server repository, the status
will change to an error state. To resolve the issue, see the troubleshooting tip for the
displayed error state.
Missing Transfer Server
repository
No Transfer Server repository is configured in View Manager.
This state does not indicate an error because you can perform transfer operations for
full virtual machines without configuring a Transfer Server repository.
However, this state does indicate an error when you use linked-clone desktops in local
mode. You cannot perform transfer operations for linked-clone desktops when no
Transfer Server repository is configured.
