HP Media Vault changed behavior

I am running Win 7 Build 7100. Until yesterday I was able to access my HP MediaVault mv2020 using my logon ID/Password.

Now, when I try to access/map the drive, I am told I don't have permission. If I go into the Map Drive dialogue box, I can logon using "Different Credentials" with my same ID/Logon.

I can access the mv2020 using Vista 64 normally, and if I go to my router, I can also access it with the same ID/Password.

I have tried going backwards to a Restore Point several days ago without joy.

Can someone direct me to the registry entries I can examine to see if I have corrupted something.

Thank you

I have been having the same problem. I have tried changing firewall settings. I changed routers. I changed network settings and user settings on the vault.
Has anyone found a solution for this?
