    Hi,

    I am quite new to WDM, but so far I am not enjoying the experience! I have installed WDM 4.9.1 on a fresh Win 2003 32bit VM.

    I work for an organisation that has Wyse terminals on a lot of sites around the UK, I am trying to audit them to find out which I need to upgrade so that we can use RDP 6 on them. Majority are S30’s I think.

    Sadly I do not have control of the DHCP which is handed out by managed routers at the sites. Does finding devices by getting WDM to scan for them ever work or should I give up now? I know that the devices are on and I can see them with IP scanner, but WDM not showing anything.

    Thanks,

    Seth

    Are you searching by subnet or IP range? Subnet search cannot work as it is a UDP broadcast.

    Hi,

    Searching by IP range. How does the search work? These sites are on DSL circuits connected together as a VPN.

    Thanks,

    Seth

    So, do you have a double NAT then? This would not work as the device would report its internat IP and WDM could not connect to the client via that IP, of course.

    No, I don’t think they are double NAT’ed, they appear just to be on different subnets of one big network. e.g. 192.168.1.x is in London, 192.168.10.x is in Liverpool. The subnet mask for each netwotk is however 255.255.255.0.

    Would that still work?

    Sure, that should work just fine.

    We also have ipvpn and a /24 subnet on each location. We have got this to work.

    We have s10, c10le, t10, x90m7 and x90c7 that all connect against the WDM 4.9.1 installation.

    We experienced the same problems as you describe. The problem was that the version of wtos was to old to be found when searching. We solved this with adding dhcp options in the dhcp server and the checked in this way. We are planning to upgrade the wtos clients in the near feature.

    If you read the release notes for wdm 4.9.1 this might help you:

    “Upgrade of Windows CE6.0 devices (C30LE, S30, V30L/V30LE)
    If you have Windows CE 6.0 devices, a WDM agent (version 4.8.16.0) is separately available for download from http://www.wyse.com product download section.”

    Since we don’t have Windows CE at our site I am not sure but it seems like you have to upgrade the wdm agenton the S30s if you are not able to use dhcp options.

    This is just my experience and if I am wrong in any assumptions I hope ConfGen corrects me. He has helped me several times already on this forum.
