    I have set up a RV042 (firmware at my office.
    At home I have installed QuickVPN version
    When I connect to the office, the VPN connection is made and I can ping all machines using their IP-adress. I also can connect to the shared drives and transfer files. So far so good.
    When I trie to use remote desktop or VNC the connection is made but the screen stays black. When using VNC the remote pc reacts to moving the mouse and sending CTRL+ALT+DEL.
    A second problem is, I can't ping the machine using their name.
    Can anyone help me out?

    Re: Black screen problem with VNC and Remote Desktop


    Had a smilar problem when first setting up a couple of WRV200s. After Hoouuurrrsssss on the phone with both Linksys and MS I finally found out that a Black Hole router had appeared somewhere between me and the remote location. I do not know if the WRV200 is at fault, but I got exactly your symptoms at 2 different remote locations (KY and PA) after setting up the new routers. There is a workaround you can use by letting your system negotiate MTU sizes; requires a regedit and addition of a couple of Dwords on the remote and local PCs. See http://support.microsoft.com/kb/314825/en-us
    After setting EnablePMTUBHDetect and EnablePMTUDiscovery on the sytems, both VNC and Remote Desktop work as they should.

    Good Luck

    i had the same problem with the rv042 and the firmware
    I also contacted the support, but they had no idea.
    I updated the router to version beta and the problem is solved.
    I think it is a bug in the firmwareversion
    Try also the version of the linksys client. There are some new features.
