Creating DNS SRV record for a Lync Installation

Creating DNS SRV record for a Lync Installation

I always seem to forget how to do this, so I�ll put it here and I will never forget.

1. Open the DNS management console.

2. Make sure to right click the domain name (Fabrikam.com)

3. Select "Other New Records..."

4. Scroll down to, and select "Service Location (SRV)"

5. Click "Create Record..." and configure the SRV record like this.

Update:

Now the tool is updated, thanks Curtis Johnstone!
The OCS & Lync Sign-In Troubleshooting Tool V3.0

Even though not updated for Lync I still like this tool
The OCS 2007 Automatic Sign-In Troubleshooting Tool V2.0

From the Lync documentation:

Create swap after ubuntu installation

Create swap after ubuntu installation

For newer version of ubuntu swap is very important. Question is why?

1. On hibernate system save all data from ram to swap.

2. When ram is full, swap is used as a secondary ram

Recently released ubuntu uses caching in ram. Its means save recently closed application data in ram, so that when you will use the application again it can load it quickly. Cache increase performance. For that ram becomes full (2GB or less). When ram fill with cache and system needs more ram it backup old cache in swap. If you dont have a swap then your system behave slow when ram is full.

What happen if you have already installed your system without swap partition? Fortunately ubuntu has option to create a swap as file.

Step 1: Allocate a file  sudo fallocate -l 2048m /mnt/swap_file.swap

Step 2: Change permission sudo chmod 600 /mnt/swap_file.swap

Step 3: Format the file for swapping device  sudo mkswap /mnt/swap_file.swap

Step 4: Add swap  sudo swapon /mnt/swap_file.swap

Step 5: Open fstab  sudo gedit /etc/fstab

Step 6: Add entry in fstab  /mnt/swap_file.swap none swap sw 0 0
