Code: set devmgr_show_nonpresent_devices=1 devmgmt.msc then when device manager starts up, I select show hidden devices. I'm also being sure to leave the command prompt open after I open the device manager. I know that the set devmgr. Bit is working, because I can see missing devices under 'other devices' that I cannot see when I do NOT do the set devmgr.
The PC I am seeing this on right now did have the zero access rootkit on it, but was removed. Not sure if this is some component of the malware that disables the ability to view these devices in an attempt to hinder removal attempts. I haven't read anything on the subject in various whitepapers on zero access, however. My Google-fu must be lacking, because I cannot seem to find any info on this issue. I found one article with no resolution that mentioned it could be a corrupted/missing component of device manager (the article was also about XP Embedded so I didn't expect much anyway). Every other result I can find only mentions how to view the category with the set devmgr. Bit, but none mentions it not actually working. I couldn't fix anything with SFC on any of the systems so far as it found nothing; and I don't know how to check for / what device manager components could possibly be missing/corrupted?

I have even tried the procedure from a command prompt run under the LOCAL SYSTEM account (like you could do by using Sysinternals PSEXEC). I have verified in the registry of the current system that there are in fact plenty of those non plug n' play devices (legacy drivers) under HKLM System CurrentControlSet Enum Root, and I have verified that none of the existing entries are malicious, as well. It just bugs me that I cannot see them in Device Manager. Am I missing something obvious? Any suggestions? Thanks in advance! Click to expand.THAT'S IT! THANK YOU THANK YOU THANK YOU! FYI, the entire registry key and all values were missing. The INF file was present in%systemroot% inf, however a right-click and install did not put the registry key back. So I exported it from a known working PC and imported it on the broken one and voila! • Anywhere access - Exchange Server 2010 helps your users get more done by giving them the freedom to securely access all their communications - e-mail, voice mail, instant messaging, and more - from virtually any platform, Web browser, or device. • Microsoft Exchange Server 2010 helps IT Professionals achieve new levels of reliability with greater flexibility, enhanced user experiences, and increased protection for business communications. • Flexible and reliable - Exchange Server 2010 gives you the flexibility to tailor your deployment based on your company's unique needs and a simplified way to keep e-mail continuously available for your users.
