When trying to access iTunes Store from iTunes installed on Windows 8.1 it crashes. Problem is that iTunes can’t find specific DLL which is used to display content of the store.

In order to fix problem cop: QTMovieWin.dll

from:  C:\Program Files (x86)\Common Files\Apple\Apple Application Support

to: C:\Program Files (x86)\iTunes

and now you can access iTunes Store without any problems on Windows 8.1.

Usually I tend to create DHCP server on Windows Server. However, sometimes there is no server on site. Only what I have are network devices, workstations and voip phones. In those cases I used to create DHCP server on switches. As environment I operate in contains mainly Cisco devices, each location has at least one or more Cisco Catalyst switches (2960 or 3560) it is possible to provide DHCP service using IOS features. Example contains DHCP configuration for network with different VLANs for data, voice and printers.

Below is short description and set of commands demonstrating how to setup:

• DHCP scopes
• Exclusions
• Define DHCP helper on the interface
• Check status of DHCP assignments

Once you add one plugin everything goes back to normal.

[root@arb-srv-01 easyforms]# composer update
Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
- yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.
- Installation request for yiisoft/yii2 2.0.7 -> satisfiable by yiisoft/yii2[2.0.7].

Potential causes:
- A typo in the package name
