Sometimes your AD has a lots of temporary users, with accounts expiring in near future, and to ensure that only legitimate users have never expiring or long expiring accounts you want to audit your accounts. To do so, perform next:
Recently I’ve got unexpected Windows server 2008 R2 reboot with some recovery reason, which is quite uninformative:
Read MoreThe process C:\Windows\system32\svchost.exe (servername) has initiated the restart of computer servername on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Recovery (Planned)
Reason Code: 0x80020002
Shutdown Type: restart
Comment:
One of the strange features of TSM AD pool is that, when you do first incremental backup (for example 10 files), then change some data (for example 5 files) you’ll get incorrect number of files with query occupancy stg=adpool command. It will show you number of files equal to 15, the same as in your primary storage pool. But if you compare sizes of pool you’ll see a difference. So do not rely only on file number in your AD storage pool.
Recently I have added new mounted volume to Microsoft cluster (lets say disk 3 mounted at m:\history), and tried to restore some old backup to it. But after I have run SQL script I’ve immediately got an SQL error:
Only formatted files on which the cluster resource of the server has a dependency can be used. Either the disk resource containing the file is not present in the cluster group or the cluster resource of the SQL Server does not have a dependency on it.
Recently we have had a very confusing incident while trying to access one of our production virtual server through vSphere client. As linux servers in default installation redraw its console only on some event (some input or output), every time we open virtual machine with linux to see its console we need to press some key on keyboard. The problem is when you just opened console in the thick client user’s input focused on the toolbar. More precisely on its first button, which is “Shutdown”. When you press this button you’ll get confirmation dialog and input focus is on the “OK” button again. So if just opened server console, without clicking mouse anywhere, and quickly press space key two times, it will immediately shutdown you server, which will cause unplanned downtime to your production system. Very disappointing application design for industry’s leader solution. By the way, vSphere webclient doesn’t have such problems.
Read MoreRecently we’ve got error installing driver on our Windows 2008 R2 server. It does not provide any specific error dialog, just constantly showing “Please wait while the application is preparing for the first use”. After you press Cancel, it gives you error message saying that installation could not be completed because other installation is in progress. The only diagnostic message in the Application log was EventID 1033 form MsiInstaller with message Installation success or error status: 1602 or Installation success or error status: 1618. Which obviously not helpful. Internet search revealed, that this message is quite common and can be caused by many things.
Recently I have stuck with error 1053 The service did not respond to the start or control request in a timely fashion while starting NetBackUP Client Service. But the error appeared much faster then 30 seconds which is actual service timeout, so the message was incorrect. The problem was that affected server was joined into MSCS to host SQL server group. So to backup MSSQL we run NetBackUP Client Service as domain user with rights to access SQL bases. To start service correctly domain user must have local server administrator right. After I’ve added this user to local administrator’s group error gone.
One of clients had problem with MSDTC service on Windows 2003 server, which couldn’t start. After short investigation I have found corresponding errors in Application log:
