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.
