hello,

when type oclist.exe in windows 2008 sp1 core machine error "no signature present in subject". have verifed event logs , dont see errors regards oclist corruption. pointer in regards appreciated.

i have tried few solutions below.

1. rebooted computer

2. checkdisk , checksum

this problem due having corrupt/missing files or unsigned drivers added.  typically when receive error "no signature present in subject" result of trying list roles or features, system event log may contain events indicate more information on details tab of event.  checksur.exe tool can helpful in determining packages/updates need re-applied resolve issue.
