WDM 4.8.5 Devices not Checking in After New DHCP server

[JoMaFe]

After changing my DHCP server on one of my subnets. None of th devices are checking in, all C90LE7. I made sure the DHCP options 187 and 192 were set on the new DHCP server. Performed a ipconfig /release,renew on all the thin clients. Still nothing.

I then removed all the devices from WDM and performed a find devices. After some time only one device checked in, but shortly stopped updating.

If anyone has any suggestions that would be great. I have WDM running on a 2008 R2 64 VM.

Thanks

Too answer my own question. I had to apply the update to the agent. from 6.0.0.26 to 6.0.0.32. My domain name was too long.
