Print Sever changing its static IP address in DNS

[KoolTech]

Hi,

 

I wonder if someone could help me or has seen this before.

 

I have a virtual Hyper-V print server that has a static IP set and I check DNS and the IP address is registered in there no problem.

 

The next day, the print server still has the same static IP address set but the DNS server now sees a different IP address, usually one of the printers IP addresses.

 

If I manually change the IP address on the DNS record back to the same as the static IP address on the print server, it all works again but the next day it changes itself back to a different IP! These IP addresses are separate to the DHCP pool

 

I tried letting DHCP set the print server IP address and again checked DNS and all okay but the next day DNS has gone back to a different IP address. Usually back to one of two addresses that are both IP addresses used by the printers.

 

I feel this has just started happening since we replaced our printers with new Ricoh printers but cant be certain.

 

If anyone has any ideas or can point me in the right direction I would greatly appreciate it!

 

Thanks.

What are the host names of the printers that it’s changing cross to?

Have you got the DNS server settings correctly configured when you switch it to static?

Can you move those printers to a different IP to see what happens?

Is the MAC address of the network interface of the virtual machine staying the same? I've had a situation before where a Windows update has, for some reason, convinced the virtual machine it has a new network card, defaulting to DHCP instead of a fixed IP address. There is, possibly, an option to randomise MAC addresses on reboot (I think some Macs now randomise their MACs, which is confusing...), that might be something to check.

You could try deleting the dns record out of dns server and running ipconfig /registerdns

My next thought is to move the printers IP to see if that helps. Everything looks correct and the host names are the same as they have always been

I have done that most mornings and it works until the next day when I check and it has changed the IP again!

Sounds like one, or more of the printers has the name of the print server set as their own hostname and are therefore registering in DNS against it. Checking the hostnames are set to a different & unique name on each printer is where I would start?

Have you got any sort of vlan in place just with you saying a different address pool ?

You could create a static entry in dns ? For print server

Thank you! I will check that this morning as they were setup by an external company so didn't think to checked this yet

that looks like it was the issue! I should have checked. Thank you so much and to everyone for your suggestions.

You could always remove the print server - go to Direct-IP printing and allow a solution like Vasion Print (used to be called PrinterLogic) manage the installation of drivers for you. There is a free trial option
