sharing failed to connect due to network issues. Try again later.

I faced an issue with Lync Application Sharing and File Transfers, where on of the users was Internal and the other was external, the sharing failed with the following message (sharing failed to connect due to network issues. Try again later.)

After investigation this was found to be caused by a firewall on the client, it was caused by Kaspersky Internet Security, so always make sure to turn off any firewall on the client computer.

Exchange 2013 and Lync 2013 Previews are now released !

Microsoft has released the Previews for Exchange Server 2013 and Lync server 2013, seems there are big architectural changes in Exchange server, as the TechNet documentation lists only two roles for Exchange Server (Mailbox and CAS), the architecture seems similar to Exchange 2003 as the CAS is also responsible for routing E-mails !.

Adobe Acrobat Professional Missing Fonts

I have faced a problem when printing MS Word Documents to PDF using Adobe Acrobat Professional 9, the file was not printed and a text file was created stating that the Cambria  font was not found and the following error:

Cambria not found, using Courier.
%%[ Error: invalidfont; OffendingCommand: xshow ]%% 

There are two solutions to this problems:
1- Quick solution: when printing go to Printer Properties then go to Adobe PDF Settings tab, and then untick the option "Rely on system fonts only; do not use document fonts"
2- The second permanent solution:
- from the same above tab, click on the Edit button next to Default Settings,  go to the Fonts tab and add the fonts "cambria"  to the always embed section like in the snap shot below:
 then click on Save As  and ok then you are done.

try re-printing your document and good luck !

Reason 442: failed to enable virtual adapter


I have faced a problem when connecting to a VPN connection using Cisco VPN client, the authentication window pop ups and after i enter the credntials with a couple of miuntes i get the following message:
Reason 442: failed to enable virtual adapter

The strange thing that it was working before, but something must changed, then i remembered that i have installed a virtual WiFi router, then i figured it out , that program enabled Internet Connection Sharing.

for the VPN connections to work you have to stop the Internet Connection Sharing (ICS) Service, change the startup mode to either manual or disabled.

then try to reconnect and your VPN connection should work fine :)
