RV042s -Mapped Drives - Slow Response

    We have a IPSec VPN created between (2) RV042 routers with firmware version1.3.8.1. using a cable Internet connection at both ends. At the Main site, there is a Windows 2003 Server that we map a drive to for the Remote XP Pro clients (in a workgroup). We map the drive using \\LAN IP Address of Server\shared folder (contains many folders), for example \\\apps.

    When we click on the mapped drive, there is a painfully slow response time before all the folders are displayed. One of the applications we run on the remote side, requires one of these folders, so the response for it is VERY slow. We have had moments where we try to ping the, an dget "request timed out" -like the tunnel drops altogether.

    We have read many posts, done other research, and it may point to an MTU issue but we are unsure how to determine the best setting. On the remote side if we go to the website Speedguide.net and run the TCP/IP Analyzer, it shows the MTU to be 1450, states it is not optimal, and recommends we increase this to 1500. We did that on the remote site's RV042, but saw no change.


    (1) What is the best test to determine what MTU setting our RV042 should have and does this override any MTU setting in the registry of our XP Pro clients?

    (2) How do we tell from the RV042 log if our tunnel has dropped it's connection?

    (3) are there any other settings we should concern ourselves with for speeding up the mapped drive response time? Note, we have another friend (not using Linksys products -using Edgewater routers), with the same exact setup, with the same problem.

    try this fix. i think this maybe the Windows XP Scheduler slowing it down.

    When you connect to another computer with Windows XP, it checks for any Scheduled tasks on that computer - a fairly useless task, but one that can add up to 30 seconds of waiting on the other end - not good! Fortunately, it’s fairly easy to disable this process.

    First, navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace
    in the Registry. Below that, there should be a key called {D6277990-4C6A-11CF-8D87-00AA0060F5BF}. Just delete this, and after a restart, Windows will no longer check for scheduled tasks - major performance improvement!

    I'm using two WRV200 and a RV042 connected to a triangle shaped VPN network. The access to remote shares through IP names is very slow. But, when I'm using NetBios names everything works many times faster.

    How do you use NetBIOS names?

    Do you mean the Registry on the XP computer that we are using to connect to the Windows 2003 Server, or did you read that we were connecting from one XP to another XP? If the former, then we will try this...thanks!

    NetBIOS names is the same as network names. the "NetBIOS broadcast" should be enabled in the advanced options of the VPN tunnel.
