Cleaning up the DFS errors

November 21, 2016

Some DFS-related errors, such as “Cannot enumerate namespace“, “Element not found” or “RPC server is not available” are related to the configuration issues in namespace. All  DFS components in registry, Active Directory and file system should be in sync. If they are not, the mentioned above errors happen. Pretty often it is easier and faster to remove DFS namespace completely and recreate it rather than to fix it. This article is about removing a DFS namespace and cleaning up all its components.

Have you ever seen it? 3.5″ Extra-High Density Floppy Disk, 4MB. If you remember, the most popular size has been 1.44 MB. 2.88 MB is also known, but 4 MB?

Motorola and Mitsubishi were the only manufacturers for floppy drives  that were able to read these floppies. Same floppies were used to backup/restore the PBX configuration.

Resetting the vCenter SSO Master Password

February 3, 2016

Yes, it happened to me too: I forgot my vCenter SSO master password, the one that used for the admin@System-Domain account. VMware KB 2034608 clearly says that “The master password is stored in the database and can only be changed by re-installing vCenter Single Sign-On 5.1 with a fresh back-end database”. It did not give me extra optimism in resolving the issue, but Ingmar Verheij gave me a hope. His article, which  you can find here, describes in full details how to reset the SSO master password. My text is just an instruction, so I strongly recommend to read Ingmar’s page first.
