DNS not registering // dhcp addresses registered as link server

    Looks like I may have gotten the DNS part down.  I needed to go into the properties for the adapter and check "Register this connection's addresses in DNS".  Is there a way to package this as on by default?

    Wow, this would fall under "huge if true."  Wasn't this basically the main reason to use PDQ Link for your VPN, so that DNS would update properly and thus PDQ Deploy / Inventory would work properly?

    I'm having this issue as well. I have 10 DHCP addresses assigned to the PDQ Link server in DHCP with Unique IDs of RAS (is this normal?) and 2 addresses assigned to my laptop in the office this morning. DNS shows my laptop under two different addresses and didn't show my laptop in DNS at all from home over the weekend. I checked the "Register this connect's addresses in DNS" setting on the adapter on my laptop over the weekend and it was indeed checked. 

     

    Does PDQ respond in these threads? I haven't seen them respond to anything yet.

    Christian -- I am curious, was your "Register this connections address in DNS" checked by default?  Mine wasn't and I had to check it to show up in DNS.

     

    Thanks,

    Yeah it was. So to be explicit - the PDQ Link Connection adapter on my laptop came out of the box looking like this:

     

    Looks like the version of PDQ Link that I have installed on my laptop is 1.0.535-Beta. What do you have?

    Same version as you.  I wonder why mine didn't have those ticked by default.  I don't recall there being any options about this when configuring the server/client.

    I went and installed the client on another machine, and all the DNS was ticked.  I wonder why my test device at home didn't have them ticked?  I'll continue to deploy to test machines and see if my initial one was just a fluke.

    Yeah I didn't see anything like that either. How many DHCP addresses is your PDQ Link server using in DHCP? Mine is using 10 even though I've assigned the server a static IP address. The MAC Address is showing up as "RAS." Only 1 of the 10 responds to ping and it's neither the IP address of the server or my laptop's IP address. I have my PDQ Link connection disconnected as well.

     

    ... okay some investigating shows it's the DHCP address of IIS on my PDQ Link Server. I only have 1 NIC adapter, though, and that one's statically assigned. What do you see? I wonder if that's a me problem.

    Ah yeah that could be it. Let me know what you end up finding out

    Okay, it was a me problem. I changed the NIC adapter type in VMware on the VM and it was still responding in the VM. After a reboot it cleared out and isn't responding/showing up anymore. 

     

    With that being said I still have 10 DHCP addresses with the Link Server hostname. I'd like to know if anyone else is seeing that? DNS only registers Link Server on the static address though. Thoughts?

    Christian -- Mine is the same way.  I only have one client, however it is currently disconnected.  DHCP is showing 10 addresses registered to the link server with MAC as RAS.  Pinging the registered addresses return destination unreachable through my NIC.

    Something to note on the DNS registration issue, it appears as though when you install the client while on the network, the adapter has the correct DNS settings ticked.  When I installed it on a machine that was not connected to the domain, but logged in with a cached profile, the DNS settings were not there.

     

    Christian -- Curious if your test laptop was connected to the domain when installed the pdq client?

    Okay good to know you see the same thing. So I just connected my laptop to my mobile hotspot and connected PDQ Link. I was given one of the 10 DHCP IP addresses so I wonder if those 10 are reserved for PDQ Link clients then? And if so I wonder where that setting is configured so I can change it post installation if I want to.

     

    If you run ipconfig /all on your PDQ Link server do you see your statically assigned NIC AND a "PPP adapter RAS (Dial In) Interface" with 1 of the 10 reserved DHCP addresses assigned to it?

     

    I can't remember if I was connected to my existing VPN when I installed the client on my laptop or not. I *think* I had it disconnected as I didn't want it potentially cause any problems. So I would have installed it under my cached domain profile on a domain joined laptop. I'm going to install it on another test system right now and see what there is to see.

    So on test workstation #2 I signed in to my domain user profile, connected the workstation to my hotspot, and disabled the physical NIC. I installed the client on Test #2 while also running the connection to PDQ Link on my laptop. Test #2 installed fine but would not connect to the VPN while I still had the PDQ Link connection up on my laptop. I checked the DNS registration info on the interface and everything looked the same as it did in the screenshot I uploaded earlier. I disconnected from PDQ Link on my laptop and tried reconnecting on test workstation #2 but no dice. After a reboot I was able to successfully connect on sign-in, however. This appears to mean that you cannot connect to PDQ Link as the same user on different computers.

     

    I ran a continuous ping to the IP address of test workstation #2 (which pulled from 1 of the 10 IP addresses) from inside the domain network and signed out of my user profile. IP address stopped responding on profile sign-out, as expected I'm sure.

     

    Same test workstation #2 different user profile not part of VPN-Users Group : Signed in and PDQ Link Client does pop up automatically but no sign-in. Try to manually connect and won't, as expected.

    Christian,

     

    Running ipconfig /all shows one of the DHCP IPs assigned to my link server, is assigned to my Link PPP adapter.

     

    Good to know on multiple sign-ins with same user account.  I'd like to test that as well.  I wonder what the condition is that is causing some of my link adapters to not have the register DNS options ticked.  I've installed on 3 clients so far.  Two of which were off domain, logged in with a cached profile, and the adapter was missing DNS stuff.  The last machine i tested on was my main workstation in the office and DNS items were ticked.

    Hi guys,

     

    Have you found a fix for this? I'm running into the same issue. My DHCP server just keeps throwing out leases to the hostname of the PDQ Link Server and every time a client connects with PDQ link is gets a new DHCP lease, but DNS doesn't update to indicate that, meaning I can't scan the machine until I manually update the DNS. 

     

    My scavenging is already pretty aggressive at 3 days, I'm not sure making it higher would help with this issue. I'd like to be to have the PDQ Link server pass on the hostname of the of the machine and actually keeps it's DHCP lease for the time it's suppose too.
