SCCM 2007 SP2. We are using in-band provisioning for our out of band management. On the whole it seems to work fine, however, there are a significant number of machines (>100) where SCCM sees the clients as "Unknown". The oobmgmt.log files on these clients all show "!! Device is already provisioned".
These are machines which have been rebuilt (not renamed) without being unprovisioned first.
I booted into the Mbex bios (CTRL P). Unprovisioned a couple of the machines. SCCM then displayed these as "Not Provisioned". They then provisioned no problem.
Because there are over one hundred of these "Unknown" machines I would like to find a way to automate the unprovisioning in the Mbex bios so that it isn't necessary to visit all the machines with this issue.
Unprovisionex.exe Utility
Have been trying to use the unprovisionex.exe utility. Windows 7 32-bit, IE10. Have tried the following:
Unprovisionex.exe -hostname hostname.domain.com -tls -full
Unprovisionex.exe -hostname hostname.domain.com -tls -ignorecert -full
Unprovisionex.exe -hostname hostname.domain.com -user admin -pass password -full
But keep getting "And exception occurred while attempting to unprovision (FULL) the system. The request failed with HTTP status 401: Unauthorized.
Web Access
I have also tried to connect as follows:
https://hostname.domain.com:16993
This gets me to a login screen but I am then unable to logon. I have tried adding the registry key FEATURE_INCLUDE_PORT_IN_SPN_KB908209.
Any help would be greatly appreciated.
Thanks.
