administrative share not created after adding an RDM to virtual server

Hi,
I had a LUN that was no longer needed on one of my virtual servers where it was added as a raw disk mapping. I deleted the disk and added the now available RDM to another virtual server. I mapped it as drive letter H and formatted it. Now, when I try to access the drive from any other machine the administrative share \\server_name\H$ is not available. I go the the server's file and share administration mmc and I see admin shares for all my RDMs except for the one I just added. No matter how I try to add the H$ it doesn't work.
Can somebody please let me know what am I doing wrong? I've never had this happen before. Every time I added an RDM in the past I got the admin share for that drive.
Thanks.

Thanks hypercat. I added the registry key per your info. I can't restart the server since it is being heavily used now. I hope to do this over the weekend and hopefully this will fix the problem. I'm still buffled as to why it did't create the admin share without this key? None of my other servers have this key, yet it always worked.

Do I also need the AutoShareWks key?

I'll report (and accept as the solution) back after the reboot.
Thanks!

Not sure why this would happen, either, but let's see if the solution works. Try adding both entries, although I'm not 100% you would need to second one. I'm not even 100% sure this will fix it, but it's worth a try. If all of the other admin shares are there, it's very odd that this one wouldn't be created automatically. Have you already tried creating a hidden share manually on the server by creating a manual shared resource for that drive and naming it H$?

Yes, I tried adding it manually, but got the message saying it already exists, yet it is not visible and not listed. I am a domain admin, so this is not a an issue of correct access rights. I asked another domain admin to access h$ and he got the same error saying that the drive doesn't exist. We'll see what the reboot does.
Thanks.

Thanks! Addin the registry value and rebooting fixed the problem.
