Недавно потребовалось протянуть несколько десятков UTP кабелей. И заново изобрел велосипед 🙂 – у нас в Монголии сложно (а точнее совершенно невозможно) купить нормальные профессиональные короба (cable-channel) и аксессуары к ним. Пришлось возиться с китайскими дешевыми и сердитыми. Замучался придерживать кабели, когда закрывал короба крышкой – и вдруг в голову пришла идея – взять лишние бросовые куски кабеля и нарезать цветные провода/пары по 20 см, продырявить короб через каждые 40-50 см двойными с края мелкими отверствиями и продеть провода – теперь осталось уложить в короб кабели и проводочками закрепить внутри короба, чтоб не вываливались и после этого закрытие короба крышкой … Read the rest
Not everybody knows that recently Veeam starts to support backup of physical servers, workstations directly to the same Veeam Repository in already existing VBR/Veeam Backup and Replication infrastructure.
If you already have ready VBR than it’s logical to backup not to mobile USB hard drive (default target of VEB) and so on, but to VBR repo. To restore i recommend to use WDS – because boot.wim in generated recovery disk easily can be imported into WDS (and all necessary NIC and storage drivers added in std way thru WDS). WDS can be on other server – just during restore process … Read the rest
Small and free Paper Cut program is very easy to install and start to use to collect information about who, when, from what workstation and how many pages printed. Program works as a service and it seems that program intercepts from spooler service all information for own reports or maybe just parses event log? Surely if you have scripting skills you will get almost the same information for free from EventLog after parsing by script – but this program is easier to setup and configure.
One more recommendation – even for network printers with NIC better to install such printers … Read the rest
It’s recommended never to disable UAC/User Access Control (there are many instructions to disable it for piracy programs downloaded from the internet, and unfortunately in Mongolia almost all computers even in enterprises have disabled UAC in windows)
The main reason to have enabled UAC is ability for the sysadmin to run installation and system configuration commands without re-login during remote or interactive sessions on asked help workstation. According to the best industrial practices you need to exclude any end user from workstation Local Administrators (depriving rights to install non-authorized programs and change/damage system configurations). If you disabled UAC then there … Read the rest
Sometimes you cannot use pxe to boot from WDS and re-image your computer (pxe damaged or you need to re-image in the field far from WDS and office LAN). In this situation you may:
- export necessary WDS image to wim file
- you will need 16gb usb flash drive (depends on the size of your customized in WDS system image)
- create by windows usb tool ordinary Windows 7 USB install disk
- rename your wim file to install.wim and copy it to USB “sources” folder just replacing existing install.wim file
- if you now start booting from a such USB disk you will

If you intensively use virtualization you may noticed that when you restore very old backup of Domain Controller (just copy of VM or just old backup) you may confront with the problem named “USN rollback”. In this case your restored VM for Domain Controller will not replicate with other Domain Controllers.
The simplest and free way to avoid a such problem is to use for backup builtin WSB/Windows Server Backup – enough to backup only System State, or if you have space BMR/bare metal recovery (allegedly only this Microsoft tool is AD aware backup tool and during restoration deletes/fixes some … Read the rest
If you use configured scheduled Windows Server Backup then you may noticed that with time all you disk space is occupied by backups – you need to configure retention for your backups:
- create scheduled task for bat file with following content:
WBADMIN DELETE BACKUP -keepVersions:14 -quiet
- run this bat script each 2 weeks
- to check :
WBADMIN get versions
Sometime your member server or workstation fails to re-sync Kerberos ticket and shows error for trust relationship :
In this case usually all admins adds this computer to workgroup (removing from AD domain) and re-adds it again to domain. For member servers it’s not always OK.
If you are provident enough you better predict a such scenario and add RSAT/Remote Server Administration Tools to your system image on WDS server, or just install it every time when you format and re-install OS. For member servers just enable RSAT feature, Domain Controllers already have it enabled. If the workstation/member server doesn’t … Read the rest
