Moving Citrix PVS database

Contrary to CTX130499, it worked perfectly fine for me to move the Citrix PVS database while the workers were online. The only thing that was important, was that offline database had to be enabled.

vMotion stops at 21%

When trying to move virtual machines away from one of our ESXi servers, the vMotion process fails at 21% with error 195887371.

I discovered lots of sites (like this and this) describing to check the network settings and service bindings. But the settings were all correct.

In the end, we had to move away the virtual machines manually by first powering them off and then we had to reboot the ESXi server. In addition, we also found out that some RAM modules failed and we had to replace them.

I don't exactly know wether the reboot or the RAM replacement did the trick, but I guess, it was the reboot.

Re-assigning tokens in ESET Secure Authentication

Recently, I accidentally deleted the information which hardware token is assigned to which user in ESET Secure Authentication (ESET SA).

Luckily, there is a log file (%ProgramData%\ESET Secure Authentication\logs\EsaCore.log) which states which token was revoked from which user:

ESET SA log

One problem is that it doesn't state the usernames but the GUID. The next problem is that the GUID mentioned in the log file is not the GUID stored in Active Directory.

I found out that ESET SA stores its data in a SQLite database. I opened the file %ProgramData%\ESET Secure Authentication\db\Users.db using SQLite Database Browser. With this file, I found out which GUID is associated to which AD user and could re-assign most of the tokens to its users.

PST file suddenly demanding password

A user has two PST files in her Outlook. Suddenly Outlook asked for a password, but the user never set a password.

The explaination for this behaviour was that Outlook somehow created new data files with the same name, but in a different folder. I removed the wrong files from her Outlook and attached the correct ones.

Windows Update error 80072f8f

Recently, I wanted to install updates on a server with Windows Server 2012 R2. Searching for and installing updates failed with error code 80072f8f. The server should download its updates from a WSUS server in a different (but trusted) Windows domain.

Common measures like using wuauclt or dism didn't work. After doing some research, I found out that the server didn't trust the WSUS server's HTTPS certificate. After deploying the root certificate using GPO and a restart, Windows Update worked again.

Again a simple problem with a simple solution. But it's difficult to find the solution…
