Constant DNS Queries

My Xerox WorkCentre 7535 is doing DNS queries about 135 times per minute (wow!).  I did a packet capture to see what's it doing and all I saw was that it was trying to query its own host name, and it is getting back the correct respond.  Is there a reason why it's query the DNS excessively for the same record over and over?  Has anyone experienced this before?

 

Sample packet capture (name x'd out):

 

No.    Time               Source          Destination    Prot     Len  Info

257    62.943055    10.10.130.3    10.10.40.2    DNS    75    Standard query 0x55b8 A p1-xx.xxx.xxxxx

258    62.957548    10.10.40.2    10.10.130.3    DNS    91    Standard query response 0x55b8 A p1-xx.xxx.xxxxx A 10.10.130.3

 

And, yes, I've already restarted the printer.  Thank you for your assistance.

Re: Constant DNS Queries

Yup, that is pretty excessive. My first "shot in the dark" would be to release it's DNS registration and see what happens.

I have never seen a report of this previously, so I have no quick fixes

Re: Constant DNS Queries

I'm not sure what did it but I tried the following first:

1. Checked Remove this Device's IPv4 DNS Registration (as you suggested).  Didn't help.

2. Checked Remove this Device's IPv5 DNS Registration at power down.  Didn't help.

3. Unchecked Append Device Domain.  Didn't help.

 

I then restarted the machine.  Voila, that worked.  I think if I had gone with just #1 as you suggested and restarted the machine, it may have indeed resolved the rabid-query issue.  Thanks!
