Having to bring in a local tech or get a swing machine are actually much more intensive than looking at it remotely for a while. But seems doubtful that it will take weeks. Only has had a few minutes of being looked at, and only today. Oh, didn't realize it was like that. No local IT, no other available infrastructure or anything kind of limits things a lot. Yeah, a LOT. If we were local and it was one of two (or more) machines, yeah, we'd happily reinstall. As it is, we are scared of the backup device failing. Which isn't terrible as it is ONLY a backup device. But taking the server offline... we are pretty dependent on it.

@tim_g said in Use DHCP option 43 on Windows Server to tell UniFi devices how to find the controller: @jaredbusch I see, so just setting option 43 on whatever DHCP server you use is all you need. Nothing hardware specific is required on the network. Correct

@bnrstnr said in Windows Server 2012R2 DHCP Server Memory Leak?: I have some warnings and errors in the event viewer that I'm going through now. Is there any reason to have IPv6 enabled if we're not using it? A lot of warnings in there about IP6 supposed to be static only. I wouldn't disable ipv6 unless you are unable to find and fix the real root cause of an issue in which disabling ipv6 may mask. https://blogs.technet.microsoft.com/askpfeplat/2013/06/16/ipv6-for-the-windows-administrator-why-you-need-to-care-about-ipv6/ https://blogs.technet.microsoft.com/jlosey/2011/02/02/why-you-should-leave-ipv6-alone/ https://cwing.wordpress.com/2013/05/20/ipv6/

@scottalanmiller said in Home Network Setup: @jmoore said in Home Network Setup: @scottalanmiller said in Home Network Setup: @dashrender said in Home Network Setup: The whole crux of my ask was - the desire to buy as few Windows Server CALs as possible. This is unrelated to the question asked, though. you know i have noticed you and dash really communicate differently. not good or bad, just different. then you both have trouble understanding the other. from the many threads i have read with you two, that is the common theme i have seen. I'd assume part of it is that I am highly literal. That tends to be a root of many communications issues for me in general. yeah i think your right you are literal. i had to adjust my communication with you. that was my fault though, i am used to having to be so unliteral with my users because i would lose them that i got into that bad habit lol. i know for me, i was not explaining my thoughts in a well laid out way and that made me harder to understand and threw you off. did i do better that time?

So coming back to this (because I was setting some more stuff up), it seems that Windows DHCP Server does understand the RFC, that is why it actually sees and uses the entire machine ID sent by default. It is other devices like my EdgeRouters that I have to use the MAC address. The only problem with the machine ID scheme is that I have no idea what it is before the machine is created. Granted this is mostly my problem because I always use DHCP reservations instead of static IP addresses (evil fucking things, those). I continue to force the new systems to use the hardware ID, because I want to only track the MAC address hex info.

Awesome thanks guys, I'll wait for the next computer to go down then I'll report back with results!

@scottalanmiller we have an ERP system that MOST of the companies work is done in. They could still use office and such, but without the link the ERP stuff is useless. Production could continue on paper, it would just slow down Email isnt local either, we use cloud based email which is stemmed from the datacenter. That is a good point thank you for mentioning that

Question: have you tried setting up the DHCP server as the time master, and having the Centos system sync time to the DHCP server (with said DHCP server syncing to NIST or whatever time source you prefer) instead of the NTP Pool? That way theoretically DHCP server and Centos should be at the same time. Just a thought.

Thanks for your support my Dear

Add-DhcpServerv4Filter is a interesting PowerShell cmdlet http://technet.microsoft.com/en-us/library/jj590751.aspx

Sure we do. NTG has 2 datacenter locations, with DCs in each. IT-ADMIN only has 1 datacenter location, so putting a DC at the remote site would be a good idea. If he/she had another datacenter location, it would be less of a concern. he not she, hhhh thanks for your suggestion, i know that the best idea is to have an additional DC in the remote location, i will try another machine and promote it in the branch office, i will not give up, because i doubt the previous ADC has something wrong in its system, if it doesn't work i will try RODC
