I have 2 unraid servers on the same network.  one is called Pipe and the other is called Tower.  For some reason when i start up Pipe server it grabs the network name Pipe and also Tower - when i ping either pipe or tower i get the same ip address of 192.168.1.143.  Under settings/Identification one is PIPE and the other was Tower.  When i ping tower it comes back tower.lan in the windows command prompt.  When i ping Pipe i get pipe (without the .lan) and both give me the same IP address.

 

Settings/Network for Tower is no bonding, no bridging, automatic IP address assignment, ip address is 192.168.1.154, dns server assignment is automatic.

Settings/Network for Pipe is same but ip address is 192.168.1.143.

 

For the purposes of figuring what the master browser is and troubleshooting i have done the following.  Renamed Tower to Flower, installed plugin Dynamix Local Master and used it to set flower as the master browser.  I also installed same plugin on Pipe and it shows Flower as the master browser.  One small note is that Dynamix calls the master browser FLOWER (all caps) and i have named it under identification settings as Flower.  

 

In the past I have used the box that is Pipe and is not supposed to be stealing the tower name as tower.  (ie i have just plugged in the usb stick and ran it off that box, i switch them around occasionally- usually when troubleshooting problems and trying to eliminate hardware).

 

One other note is that I do use my router to reserve the address 192.168.1.143 for Pipe, but not for tower.  For some reason It crashed everything on my network when i set dhcp to be reserved by router for Tower at 192.168.1.154. - Any ideas why that would happen?

 

Anyhow i have been pulling my hair out on this and in addition i am now having permission problems for samba shares which i will post as a separate question.

 

I have run 

 

Now looking at my logs i see a ton of input output errors on Flower - indicating some serious problems with Flower.  also callback trace issue  I will post a separate question with diagnostics on that.

Sure you don't have multiple DHCP servers on your network?

There is a possibility this could be the problem.  I have used a 2nd router with dhcp disabled for years to expand my wifi to my 2nd house.  It is possible that there is a residual address reservation, just for this Tower/Flower Mac address.  I will check that out tomorrow and post again. Thanks for the excellent troubleshooting suggestion.  This has been driving me nuts!

Pretty sure this was the problem - thanks for your help.
