Losing Default Gateway on ThinPro 7.2

[tkmat]

After upgrading the image from ThinPro 7.1 to 7.2 I'm getting a small number of T630's that, days later, have lost their default gateway and dns addresses completely. Still connected with correct ip and subnet. Ethernet connection.  Has anyone encountered this? As a result I'm unable to use HPDM to fix. Yesterday I had one device out of 7 with this problem, and it was 14 days after re-imaging it with 7.2.

Please try installing with fresh ThinPro 7.2 SP6 and test the unit. Do not install SP10.  If the issue still persist I would suggest to reach out to the HP thin client support team.

I have the same problem with SP10. I'll try and downgrade to SP6

Did the downgrade to SP6 seem to solve? We are having the same problem.

Did you ever find a resolution? We are having the same problem. This is happening to us (seemingly randomly) across maybe 6 of 10 devices.

SP6 didn't correct the issue. It seems to be very sporadic within our fleet of T630's. Reimaging seems to have helped in cases where we were actually onsite and able to do that with usb stick etc. In two other cases HP replaced them thinking it was a hardware issue. It still happens occasionally with random devices. Frustrating not to know what the cause is. I hope that helps.

Definitely helpful to confirm I am not going crazy.

One of the things I've just discovered is switching into the admin user -> Control Panel -> System -> DHCP Options -> Show All Options -> Uncheck DHCP Code 003 and 006 for Routers and DNS Servers -> Apply -> Check back on -> Apply.

Helpful if you are not on site and comfortable walking a user through it. That is my only option at the moment, but I think we'll be moving on to a different model, unfortunately. Too many other little issues as well.

kindly open a case with HP Support. This might have to be looked at by experts on what is causing this issue.

I've discovered that ThinPro 8.0 seems to be working well. The other thing I changed that seemed to have an impact was the name of the device. A few of my devices had a name structure like MT22-SURNAME.DOMAIN.COM or something. Removing the DOMAIN.COM portion of the device name seems to have resolved on ThinPro 7.2 SPX models, however, with it being random, I cannot say for sure. Might be worth checking in your environment.
