"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.
