Windows 10: "RPC server not available" - Computer Management/Disk Management

For months now I have been unable to connect USB drives automatically in Win 10. When I go to Computer Management/Disk Management I often see the drive there, but with no drive letter, so I have to manually add the drive with a new drive letter.
If I try to "Refresh" or "Rescan" the disks in Disk Management I get either a "Remote Procedure Call failed" message or "RPC server not available" message.

Recently I upgraded my computer to a new everything, (mobo, USB ports, etc.) but cloned the system drive. That didn't help resolve the issue, so it's obviously not hardware but something in Windows. That being said, I am on a MSI Z390-A Pro mobo, i7-9700K, GTX 1660, 32GB Kingston

I have AVG free virus and Malwarebytes Premium and Windows Defender Firewall

Here are the things I have already tried to fix this:
Checked to make sure of the following settings in "Services":
DCOM Service Process Launcher Automatic
Remote Procedure Call Automatic
Remote Procedure Call Locator: Manual
Did not help

I have done CMD line sfc /scannow which reported some files were replaced. Did not help

Went to ncpa.cpl and made sure File and Printer sharing was on; that Internet Protocol Version 6 checked. Did not help.

Went to Windows Defender Firewall and added everything titled "Remote..." - Did not help
Turned off Windows Firewall entirely - Did not help.
Turned on Windows Firewall with the option of "Notify me when blocking a new app" - Did not help

Checked registry entries for RpcSs, DcomLaunch, RpcEptMapper, and all were set correctly for Dword=2.
Did not help.

Flushed DNS. Did not help.

I am at wit's end. I do not know what else to do. I did all these things by rote from advice from several sites, I don't have a deep knowledge of Windows. I just want to be able to get to my drives without a lot of hassle.

Thanks in advance for any suggestions.

Unable to Connect to Logical Disk Manager Service Error in Computer Management

WELL, I'll be an "S.O.B."! I got it... lol, just now!

Apparently, & I am going to record this & BOOKMARK/FAV it in my webbrowsers as "HOW TO FIX LOGICAL DISK MANAGER HASSLES" (lol), it is SOMETHING in my services!

You need THIS list of them running (provided you have them online that is, some OS won't have SOME of these (this is Windows Server 2003) & some are 3rd party & won't matter):





* NO SAFE MODE REQUIRED - THIS FIXED IT, PURELY SERVICES RELATED... oddly, no "dependencies" other than the ones the services need (RPC & Plug n Play) are listed in the 2 services for Logical Disk Management... it's like MS missed (somehow) the fact that there IS other dependencies on other services than what they list!

That list above is PROBABLY "overkill" & it is only a fraction of that list above, but the point is there... with ALL of those active? Logical Disk Manager "gets its act together" again & works!

APK

P.S.=> BRB, with screenshot of services & their startup status needed for this to work, in case anyone else hits this... it is a real you-know-what if you can't get to a disk to format it, lol... so, recording it for everyone's sake! apk

 

Unable to Connect to Logical Disk Manager Service Error in Computer Management

I keep seeing the err msg in compmgt.msc (Computer Management) when I go to look @ my diskdrives (I have a new one, larger for data storage now)...

Anyone ever see this before & have to get around it/fix it?

The ODD part is, the 2 services associated w/ it (Logical Disk Manager & Logical Disk Manager Administrative Service) startup, NO problem in services.msc...

Yet, when I go to use the Disk Management portion of Computer Management, I still cannot get into it to format that new diskdrive I got!

(CompUSA store in my area closed down @ a local mall, & I picked up a Samsung SpinPoint 250gb disk to move files from a WD "Raptor" 74gb I have here which is only 7gb away from being totally full).

So, then I checked the service dependencies & none of them (Plug & Play, + RPC) are turned off either... they are on right away as "Automatic" services when I boot up.

Would the shares on the disks matter here? OR, since I set the Logical Disk Manager 2 services noted above as "MANUAL", do you think setting them to AUTOMATIC on startup might help here??

Thanks... this is "perplexing me" greatly!

Disk management console view is not up-to-date

i dont know how to fix your disk management, but i can fix your partition problems...




open up Command Prompt with admin rights. (Right click, run as admin)


enter in
DISKPART
list disk

then find the Disk number for your Raid array... lets call it number 7 ( you can tell what disk is what by the total size)
type in

Select Disk 7
List Partition (will give you a list of all the partitions..)
Select Partition 1 (im assuming you only have 1 partition on Disk 7) repeat this step if you have more partitions.
ASSIGN


that should get the array up and running ready to use.


EDITED.

any problems, post back ^^


Still EDITING *Stick Out Tongue

side question, have you tried restarting the PC?
