idac6 bad data returned from winrm commands

Issuing winrm commands to idrac returns bad data or no data. There are a bunch of servers that don't work but approximately 5x that amount that do work okay on the same FW revisions. The issue is on both R610 and R410.

Pretty standard FW level:
Idrac=1.90
LCC=1.5.5.27

The following example command returns bad data which is consistent across all that are broken. For starters the model is not T710 and the ChassisServiceTag doesnt match the ServiceTag like it does normally if the system is not a blade. All the bad data shows the model as T710 and the ChassisServiceTag as JDTR5L1. They also all beleive they have only one dimm installed. BIOS version is incorrect but seems to also be incorrect on the ones that are working.

NOTE: Replace with idrac name or IP. Change password if it is not the default of calvin.

I tried "racadm racreset hard" with no success. Next step is power drain. After that is factory defaults. After that is LC Repair which seems to fix a lot of random issues.

I opened a dell case already but would like to know if anyone ever seen this issue?

Thanks for any help.
