Get-BpaModel enumerates through all available bpa models. I run it from one of our dc with domain admin privileges.
It started to fail today on fourth model (it enumerates ADRMS, CertificateServices and DHCPServer) - then immediatelly comes index out of range error (where "Microsoft/Windows/DirectoryServices" should come).
The same command works on other DCs without problems. What's stranger, this was still working yesterday. I haven't found anything about this error for this cmdlet over internet. The server was rebooted, but no luck. The same problem occurs now when i try to run Get-BpaResult on this machine for the very same model. Could it be, that the maximum number of reports have been generated and one has to remove them somehow?
