HAFEED HASSAN AP

To troubleshoot this problem, I did restart of that laptop and tried, changed LAN cable and port, but not worked. At last, I deleted the concerned LAN drive from the following location Go to Control Panael - >Device Manager ->Network Adapters ->Intel ....() and restarted the Laptop. Now I think it reset the adapteer automatically, but now it works fine both LAN and wifi. 

I had to solve such issue for one of my colleagues before The following microsoft page was helpful to troubleshoot this problem. https://support.office.com/en-ca/article/I-can-t-change-the-formatting-of-a-message-when-replying-or-forwarding-f6c1b3ae-b949-4f91-b5a7-e3cf152b4590 Feel free to comment. Thank you all.

I have to solve this issue once for a user. So the following workaround helped me. I renamed the preference file as Adobe says this will recreate automatically when we restart illustrator. I did this in Windows 8. So the location was as follows Users\ \AppData\Roaming\Adobe\Adobe Illustrator 19 Settings\en_US*\x64*\Adobe Illustrator Cloud Prefs   Users\ \AppData\Roaming\Adobe\Adobe Illustrator 17 Settings\en_US*\x64*\Adobe Illustrator Prefs I think Adobe Illustrator 19 may vary such 17 or so and so.  Adobe Illustrator Cloud Prefs I renamed Adobe Illustrator Prefs and to Adobe Illustrator Cloud Prefsold and Adobe Illustrator Prefsold. Then I reatrted the illustrator. Now above message is not appearing when closing illustrator.  Feel free to leave your comments and suggestions.
